Enhancing formability in deep drawing: A 3D finite element analysis of plastic wrinkling in AA2090 Al–Li alloy

Deep drawing is a manufacturing process used to produce billions of metal containers, crucial for the aerospace industry in forming thin-walled components efficiently. However, wrinkling due to compressive instability remains a significant challenge in sheet metal forming. This study investigates plastic wrinkling in sheet metal forming to enhance the final drawn shape. A 3D finite element model using ABAQUS/Explicit was developed to examine the effects of mesh topology, blank holder force, and sheet thickness on wrinkling in AA2090 Al–Li alloy. The finding indicates that that an increase in blank holder force increases wrinkle number and amplitude. Additionally, it was found that a 2000 N blank holder force is necessary to prevent wrinkling.

Основные предвестники формирования общепринятых практик осуществления мультимодальных перевозок

The article provides an overview of the history of the emergence of containers, within the framework of such a phenomenon as the container revolution, and also analyzes the modern potential of large transport and logistics infrastructure facilities, as a result and result of the container development trend. As part of the review of the development of modern trends in multimodal transportation, the issue of containerization is quite important, because today a container is not only an equipment for cargo transportation, but also an integral part of the supply chain, and is also able to significantly influence the formation of market tariffs for cargo transportation. Containerization of cargo transportation contributed to the formation of a modern transport and logistics paradigm in the context of international transportation, and also influenced the evolution of existing types of vehicles and special equipment, adapting them to mass transportation of metal containers. Over the history of its existence and development, containers have been adapted for the transportation of a wide variety of types of cargo from dangerous and temperature to bulk and bulk. In this article, within the framework of the calculation unit for assessing the potential of the modern global transport and logistics system, an analysis of the capacity of the largest marine infrastructure facilities - seaports is used, since it was with sea transportation that the containerization process began.

Safely Managed Barbeque Use of Charcoal as Traditional Renewable Energy

While coal is a fossil fuel, traditional charcoal is an inherently renewable energy source. In addition to fuel, charcoal can also be used as a functional material such as adsorbents and catalysts. Charcoal is still used for heating in safe cooking situations, such as barbecues. However, in recent years in Japan, there have been many cases of barbecue fire accidents. This study is a case study in which the author experimented with charcoal (made from Malaysian mangroves) barbecue using a safe method within an established facility. Based on past fire incidents, the main causes are the ignition of liquid or fluid combustion aids, the spread of sparks bythe wind, and insufficient trailing fire. In this case study, under calm wind conditions (artificially fanning at an appropriate level of strength), using a solid firelighter, and collecting used and extinguished charcoal ash in a metal container, these three points was found to be important for safety fire management in barbeque.

Nitrogen-rich skeleton reassembled ECOFs as energetic materials with low sensitivities and good corrosion resistance

Corrosion between energetic materials and metal containers can accelerate material aging and failure, significantly affecting the safety, reliability, and lifespan of ammunition systems. To address this challenge, we propose the construction of energetic covalent organic frameworks (ECOFs) as a promising solution. We introduce a straightforward method for synthesizing nitrogen-rich ECOFs. The synthesized ECOFs were characterized through powder X-ray diffraction (PXRD), solid-state nuclear magnetic resonance (ssNMR), and Fourier-transform infrared spectroscopy (FTIR). These frameworks exhibit remarkable thermal stability, with decomposition temperatures above 285 °C. Notably, they display low sensitivity to non-explosive stimuli, as evidenced by impact sensitivity over 60 J and friction sensitivity over 360 N. The anti-rust properties of the ECOFs were further evaluated using Tafel curve analysis, highlighting their exceptional resistance to metal corrosion. Particularly, ECOF-3, synthesized from triaminoguanidine nitrate and 5-nitro-1,3-benzenedicarboxaldehyde, stands out for its superior steel corrosion resistance. These ECOFs have potential applications as high-energy, anti-corrosion coatings materials.

Suitability of aromatic polyurethanes for use in nuclear applications

Plastic bags are used to facilitate the storage and transport of nuclear materials. In case the storage container becomes damaged, these bags act as a protection barrier against possible contamination. Polyvinyl chloride (PVC) is a polymer commonly used in such applications, but unfortunately, it contributes to the corrosion of the metal container due to HCl evolution. Thus, this work evaluated aging effects on chemical and thermo-mechanical properties of aromatic polyurethanes with the intent to find a replacement for PVC. Aromatic poly(ether)urethanes were aged for up to 21 months under combined gamma irradiation and thermal treatment conditions. A few samples were also placed into actual nuclear storage containers and aged for a similar time period. Experimental techniques, such as FT-IR, NMR, mass spectrometry, TGA, DSC, and tensile tests were employed to characterize two types of polyurethanes, one with and another one without a flame-retardant additive. Our unique aging approach shows that these aromatic polyurethanes are well placed to substitute PVC bags and thus, avoid corrosion of storage metal containers used by the nuclear industry.

Alkali-activated geopolymers based on calcined phosphate sludges and metakaolin.

The extraction of phosphorite ore in Tunisia has resulted in the discharge of substantial amounts of phosphatic sludge into the region's water system. To mitigate this environmental issue and prevent heavy metal leaching, a geopolymerization process was employed using two types of Tunisian calcined phosphate sludges (Cal-PS1 and Cal-PS2) as substitutes for alkali-activated metakaolin. This study aimed to investigate and compare the physical and mechanical properties of the resulting geopolymers. The optimal substitution ratio of metakaolin with calcined phosphate sludge was determined to be 1.5, equivalent to 20 wt.% of calcined phosphate sludge. Compressive strength tests conducted after 28 days of curing revealed values of 37 MPa for Cal-PS1 specimens and 28 MPa for Cal-PS2 geopolymers while compressive strength of geopolymers soaked in water for 28 days showed a decrease with the addition of phosphate sludges. The specific surface areas of Cal-PS1 geopolymers ranged from 16.3 to 16.9 m2/g and from 17.62 to 18.73 m2/g for Cal-PS2 specimens exhibiting a mesoporous structure. The elasticity modulus of the geopolymers was found to increase with the increase of the apparent density of geopolymers and with the sludges content but it tended to be lower than the Portland cement elasticity modulus. Leaching test was conducted to evaluate the potential environmental applications of the geopolymers. This test demonstrated effective containment of heavy metals within the geopolymers' network, except for low levels of arsenic.

Corrosion Induced on Aluminum by Biodiesel Components in Non-Oxygen Environments.

Biodiesel is a mixture of saturated and unsaturated Fatty Acid Methyl Esters (FAMEs) whose composition affects the corrosion behavior of metal containers during storage. This study examines the effect of the C=C bond present in selected FAMEs (Methyl Stearate, Methyl Oleate, and Methyl Linoleate) in aluminum corrosion in the absence of oxygen. First, mass loss assays were carried out at 100, 200, and 280 °C for 1000 h using pure Methyl Stearate (MS), 5% Methyl Oleate in Methyl Stearate (MS-5% MO), and 5% Methyl Linoleate in Methyl Stearate (MS-5% ML). Next, chemical changes in FAMEs were studied using FTIR, TGA, and GC/MS. SEM/EDS analysis allowed us to inspect the aluminum surfaces and their chemical characterization. We estimated higher corrosion rates for MS assays than those of unsaturated methyl ester mixtures. In a separate set of experiments, we used electrochemical techniques (potentiodynamic polarization, linear polarization resistance, and electrochemical impedance spectroscopy) to investigate aluminum corrosion induced by thermal-degraded products from FAMEs at 100, 200, and 280 °C for 300 h able to dissolve in aqueous extracts. These electrochemical experiments revealed that the products in the aqueous extracts from the unsaturated methyl ester mixture form a passive layer on the Al surface thicker than pure MS at the corresponding degradation temperatures.

Indium partitioning between silicate melts and magmatic fluids: implications for indium ore genesis and the tracing of magma degassing

Most of the global indium resources are from deposits associated with felsic rocks. Considering that the indium concentration in the average upper crust is extremely low, magmatic-hydrothermal processes play a critical role in the enrichment and mineralization of indium. However, the extraction efficiency of indium by magmatic fluids remains unclear. We performed experiments at 800 °C, 150 MPa and oxygen fugacity of Ni-NiO buffer to determine the partition coefficient of indium between aqueous fluids and granitic melts (DInf/m). To counteract the rapid loss of indium into the noble metal container wall, the DInf/m were obtained by the method of local equilibrium between microscopic-sized fluid bubbles and surrounding silicate melt. The results show that indium has the highest fluid-melt partition coefficients of all metals investigated so far. At a constant aluminum saturation index (ASI = 1.07–1.12), DInf/m correlates linearly with the total Cl concentration in the coexisting fluid (mCltotal), increasing from 61 ± 11 (1σ) at mCltotal = 1.0 mol/kg H2O to 895 ± 105 (1σ) at mCltotal = 16 mol/kg H2O. When the HCl concentration in the solution increases from 0.13 to 0.49 mol/kg H2O at a fixed mCltotal = 2 mol/kg H2O, DInf/m increases parabolically from 129 ± 21 to 320 ± 24. The observed partitioning data suggest that indium was dominantly present as In(OH)2Cl in the low-HCl and In(OH)Cl2 in high-HCl aqueous fluid at the experimental conditions. Numerical modeling indicates that the extraction efficiency of indium from S-type felsic magmas is very high (>85 %) and magmatic fluids may be the major source of indium for most indium deposits. Due to the high DInf/m values, fluid saturation and exsolution result in a sharp drop of indium concentration in both the residual melt and crystallized minerals, which makes the indium concentration in whole rock and minerals an indicator of fluid exsolution.

A non-invasive short range acoustic technique for liquid level measurement in containers

Techniques to measure liquid level in containers and vessels non-invasively are of great interest for the manufacturing, chemical industries, and energy sectors. Most commercial solutions use invasive techniques, which are not always practical and can lead to unsafe conditions when measuring devices encounter high pressures or hazardous chemical contents. In this study, a portable, non-invasive acoustic liquid level identification technique is developed. The technique relies on comprehensive analysis of acoustic guided wave modes in the container walls and their coupling to liquid contents to determine the optimal sensor separation distance and excitation signal characteristics, resulting in liquid level determination with high accuracy and precision. First, dispersion characteristics of guided wave propagation in container walls in contact with a liquid boundary are studied in detail. Based on the dispersion analysis a general-purpose short-range liquid level detection methodology is developed. The developed methodology is then validated using numerical wave propagation simulations and experiments on various metal containers with different physical characteristics, illustrating the versatility of the method. Compared to existing techniques, which are optimized for specific applications, the proposed method, due to its short range and non-invasive nature, has the potential for universal applicability on virtually any container, irrespective of its shape, size, wall-thickness, and whether it has any internal components.

Experimental and numerical investigation on energy-saving performance of radiative cooling coating for metal container office

Radiative cooling coating (RCC) embedded with randomly distributed particles is a scalable, cost-effective, and reliable material that can enhance the energy efficiency of the building envelope. Many RCC materials with excellent cooling potential have been developed recently. However, there is a lack of holistic experimental and numerical demonstrations of RCC’s energy-saving potential in real-world applications. In this research, by randomly distributing commonly used functional fillers into a polymeric matrix, an RCC material was developed and applied to an in-service metal container office at a construction site in Hong Kong. Parallel tests were conducted using another identical container office with a conventional white coating for comparison. The inner and outer surface temperatures of the two container offices, their indoor air temperature, and the electricity consumption of their air-conditioner system were measured and compared. The field-test results indicated that the RCC could reduce the container office’s surface temperature by up to 18 ℃ and save 23.5% of electricity consumption under Hong Kong’s climate compared to the conventional white coating. Furthermore, the numerical simulation model for the metal container office was developed in EnergyPlus and validated by the experimental results. Then, the simulation model was used to evaluate the overall energy-saving performance of the RCC in five different climatic regions in China considering different solar reflectivity values. It was found that in tropical or subtropical cities such as Hong Kong, with the solar reflectivity of the RCC increasing from 85% to 95%, the annual energy load saving rate increases from 19.2% to 30.9%. In other climatic regions, the increase in solar reflectivity will bring a significant increase in the heating load penalty that outweighs the cooling load savings. Therefore, in regions with hot summers and cold winters, optimizing the solar reflectivity of RCC by considering the offset between the cooling load saving and heating lead penalty is highly desirable in order to achieve the best annual energy-saving performance.

Assessment of anthropogenic particles content in commercial beverages

Microplastic (MPs) pollution is a current global concern that is affecting all environmental compartments and food sources. In this work, anthropogenic particles occurrence (MPs and natural and synthetic cellulosic particles), have been determined in 73 beverages packed in different containers. Overall, 1521 anthropogenic particles were found, being the lowest occurrence in water samples (7.2 ± 10.1 items·L−1) while beer had the highest (95.5 ± 91.8 items·L−1). Colourless/white particles were the most detected followed by blue and red colours. The highest mean size was 783 ± 715 μm in soft drinks. Cellulosic, both natural and semisynthetic particles, were the composition mostly found but regarding plastic polymers, it was polyester. Phenoxy resin particles from the can coatings were also identified in all metal containers which indicates that leaching from the packaging may be happening. The total estimated daily intake were 0.077 and 0.159 items·kg−1 body weight (b.w.)·day−1 for children and adult population, respectively.

Flame Heat Sources as a Sustainable Method of Protecting Fruit Orchards against Frost in Poland

One of the key factors affecting the yield of fruit orchards is their protection against spring frosts. This paper presents the methods currently used (like anti-frost nets, chemical agents, etc.) and proposes an alternative method of raising the temperature around fruit trees using flame heat sources with a suitable heating power. Flame heat sources in the form of metal containers filled with paraffin were utilised in this experiment. The effect of the flame heat sources on the relative increase in the temperature of a wooden surface (simulating trees located in Rzeszow, Poland) depending on the distance from the heat source was measured and estimated based on mathematical models. Based on the results of experimental work, an optimal placement of flame heat sources (1.58 m from each tree) was proposed for orchards of semi-dwarf fruit trees. The proposed modifications of the flame heat sources to incorporate infrared radiation converters resulted in a greater increase in the temperature of the wooden surface. The analysis of the available economic and environmental data showed that the proposed method may be a competitive alternative to the standard method of protection. If the flame heat sources are filled with combustible materials derived from renewable sources, such as those produced from fats, the overall CO2 emission balance for this solution will be significantly more favourable. The use of flame heat sources does not necessitate the introduction of permanent changes in the environment, as is required in cases when irrigation infrastructure is installed.

Analysis of heat-loss mechanisms with various gases associated with the surface emissivity of a metal containment vessel in a water-cooled small modular reactor

In various small modular reactor (SMR) designs currently under development, the conventional concrete containment building has been replaced by a metal containment vessel (MCV). In these systems, the gap between the MCV and the reactor pressure vessel is filled with gas or vacuumed weakly, effectively suppressing conduction and convection heat transfer. However, thermal radiation remains the major mode of heat transfer during normal operation. The objective of this study was to investigate the heat-transfer mechanisms in integral pressurized water reactor (IPWR)-type SMRs under various gas-filled conditions using computational fluid dynamics. The use of thermal radiation shielding (TRS) with a much lower emissivity material than the MCV surface was also evaluated. The results showed that thermal radiation was always the dominant contributor to heat loss (48–97%), while the conjugated effects of the gas candidates on natural convection and thermal radiation varied depending on their thermal and radiative properties, including absorption coefficient. The TRS showed an excellent insulation performance, with a reduction in the total heat loss of 56–70% under the relatively low temperatures of the IPWR system, except for carbon dioxide (13%). Consequently, TRS can be utilized to enhance the thermal efficiency of SMR designs by suppressing the heat loss through the MCV.

신라 고분 부장 금속용기의 등장과 전개

The purpose of this study is to focus on the burial of metal containers, which is a features of ancient tombs from the Silla Dynasty of the Three Kingdoms, to gather metal containers buried in ancient tombs and graves in and outside of Gyeongju to trace the meaning of burying metal containers with the dead in the Silla society. Metal containers buried in the ancient tombs of Silla range in materials from gold to silver, gilt bronze, bronze, and steel, and also have diverse types such as personal plates for food call gobae, wan, sohap, etc., cooking containers such as sotga and siru, storage containers such as janggyeongho, and even containers used for rituals like jeong, chodu, and choho. Burial of such metal containers are materialistic expressions of burial customs and belief of the afterlife are concentrated in Gyeongju, which was the center of Silla, while being buried in ancient tombs in some other areas outside of Gyeongju. Therefore, this study conducted analysis focusing on two aspects. metal containers buried in ancient tombs were reviewed to examine the types of metal containers, while on the other hand. Results of this showed that in addition to the temporal development mode of ancient tombs in which metal containers were buried, this practice spread to areas outside of Gyeongju as time passed. Based on this, the meaning of burying metal containers in tombs of the Silla society was evaluated. Meanwhile, the burial of metal containers also had social meaning. In the center of Silla, multiple metal containers with various materials and types were buried in the greatest tombs, and this custom of burying metal containers spread to the tombs of people of lower status. It is evident that in the fifth century and latter Silla Dynasty, the burial of metal containers was widely practiced among the upper echelons in central Silla. Burial of metal containers outside of Gyeongju were found after the late 5th century, and among the various regions that shared the ancient tomb culture of Silla, metal containers were found only in the ancient tombs of Gyeongsan, Daegu, Changnyeong, and Yangsan, and therefore, it was judged that this could be interpreted as the relationship between the central and local governments. Just like other artifacts that show hierarchy, the burial of metal containers can also hint to the relationship of the central and local regions, and it can be presumed that areas with ancient tombs that buried metal containers had higher status compared to other regions.

Qualitative and quantitative analysis of cresols found in maskwio'mi (birch bark extract)

Maskwio'mi (Mi'kmaw language for “oil made from birch bark”) is a traditional topical skin medicine of the Mi'kmaq people of Atlantic Canada and is produced in a torrefaction process by heating birch bark ( Betula papyrifera, paper birch) inside a metal container in a fire. The resulting viscous, oily mixture is traditionally mixed with goose fat or bear grease to create a topical salve that is subsequently applied to affected skin areas. When birch bark is exposed to high temperatures, pyrolytic chemical processes produce a complex mixture of pharmacologically active compounds, including potentially harmful side products such as ortho-, meta-, and para-cresol. This study discusses the qualitative and quantitative GC-MS analysis of cresols found in maskwio'mi and the challenges of the complex organic matrix. Using caffeine as an internal standard, ortho-, meta-, and para-cresol in birch bark extract were determined to be in the approximate order of 50–1500 ppm range with 3.24 ± 0.09 × 102 ng mg−1 (324 ppm), 8.7 ± 1.0 × 102 ng mg−1 (87 ppm), and 12.4 ± 1.6 × 102 ng mg−1 (1240 ppm), respectively, and thus suitable by Health Canada and FDA cosmetics regulation standards when the extract is co-formulated in creams to concentrations of 0.1–5 wt.% for topical use.

Content and Dispersion of Ferroalloys in the Coating During Microarc Alloying of Steel

Introduction. The main disadvantage of traditional processes of diffusion surface hardening of steel products is its long duration. Therefore, the problem of intensification of such processes is relevant. To solve it, the use of high-energy effects on the material is proposed, which allows us to obtain a hardened surface layer from a coating composed of ferroalloy powders containing alloying elements. There is no data in the literature on the required content and dispersion of such powders in the composition of the coating. The aim of this study was to select the particle size of ferroalloys and their concentration in the coating to achieve the most effective hardening of the processed product.Materials and Methods. For experimental studies, cylindrical samples made of steel 20 with a diameter of 12 mm and a length of 35 mm were used. On the surface of these samples, an alloying coating containing ferroalloy powders and an electrically conductive gel as a binder was applied. After that, the samples were immersed vertically for half their length into a metal container, which was then filled with carbon powder with a particle size of 0.4–0.6 mm. Then an electric current of 2.5 to 3.0 A was passed in the circuit power source — container — carbon powder — sample. The duration of the process was 2–8 minutes.Results. The calculated estimation of the electrical conductivity of coal powder was performed, and the thermophysical parameters of microarc heating of steel were calculated. These include the power released by electric current on the surface of the steel product, the density of the heat flux, and the energy of a single microarc discharge. The expressions for calculating the particle size of ferroalloy powder were obtained, as well as the experimental dependencies of the diffusion layer thickness on the particle size of ferroalloys and their content in the coating.Discussion and Conclusion. The results of this study have allowed us to determine the size range of ferroalloys and their content in the coating. This information is essential for optimizing the alloying process and ensuring the most efficient surface hardening treatment for steel products. The data collected will be used to develop improved technological processes for the surface hardening process, leading to improved product quality and performance.

Development of an on-demand flooding safety system achieving long-term inexhaustible cooling of small modular reactors employing metal containment vessel

This paper proposes a flooding safety system (FSS) and its operation strategy that can provide long-term safety and effective maintenance for modules of small modular reactor (SMR) and metal containment maintained at dried environment during normal operation. During hypothesized accidents, the FSS re-collects the evaporated steam into the common pool by the condenser installed above the common water pool and provides an emergency coolant for the cavities and auxiliary pools. This study suggested that the condensate re-collection strategy using the FSS can effectively delay the depletion of available water in response to the accidents. Without re-collection, the achievable grace periods ranged from 44 to 1507 days for six-module and one-module accidents, respectively. However, with a full re-collection (ratio = 1.0), the time to total depletion of emergency coolant was estimated indefinite. Even with a partial re-collection ratio of 0.3, a grace period of 83.5 days could be ensured for a six-module transient. This study reported the effectiveness of condensate re-collection and the FSS as an innovative safety management strategy and system. Employing a condensate re-collection strategy with a high re-collection ratio can enhance the long-term safety and effective convenience of SMR operations and maintenance.

Comparing commercial versus low-cost gelatinous phantoms for ultrasound-guided needle tracking: A randomized crossover trial, among emergency medicine residents.

The objective of this study was to devise a low-cost indigenous gelatin-based vascular phantom and to compare this newly constructed phantom with a commercially available phantom. This was a randomized crossover study conducted at a tertiary care hospital of India. The aim of the study was to develop a prototype low-cost gelatin-based vascular phantom and compare it with a commercially available phantom. Gelatin, psyllium husk, corn starch, antiseptic liquid, food-coloring agent, latex balloons, and metallic containers were used to prepare the gelatin phantom. The newly prepared gelatin model was labeled "Model A" and the commercially available gelatin model was labeled "Model B." Emergency medicine residents (n = 34) who routinely perform ultrasound (USG)-guided invasive procedures were asked to demonstrate USG-guided in-plane and out-of-plane approach of needle-tracking in both the models and fill out a questionnaire on a Likert scale (1-5). An independent supervisor assessed the image quality. The cost of our phantom was USD 6-8 (vs. USD 1000-1200 for commercial phantom). The participants rated the ease of performance and tissue resemblance as 4 (interquartile range [IQR]: 4-5) for both the models "A" and "B." The supervisor rated the overall performance as 4 (IQR: 3-4) for both the models. In all the parameters assessed, model A was noninferior to model B. The indigenously developed vascular phantom was noninferior to the commercially available phantom in terms of tissue resemblance and overall performance. The cost involved was a fraction of that incurred with the currently available commercial model. The authors feel that gelatin-based models can be easily prepared in resource-constraint settings which may be used for USG-guided training and medical education in low- and middle-income countries.

A Case of Upper Limb Amputation Managed with USG-guided Continuous Infraclavicular Nerve Block for Improved Postoperative Analgesia

Phantom Limb Pain (PLP) is defined as any perceived painful sensation localised to the region of the amputated body part, while phantom limb sensations are non painful sensations emanating from the phantom limb, including proprioceptive awareness, kinetic, exteroceptive, and superadded sensations. The mode of anaesthesia administered during amputation is an important factor in determining the emergence of PLP or phantom sensations. The majority of patients requiring emergency care are victims of traumatic injuries to the upper limbs, which are most often treated conservatively. The authors present the case of a 67-yearold male patient who sustained a fall on his arm while carrying a metal container, resulting in a laceration to his left arm that led to disruption of brachial artery blood flow, necessitating amputation. Although upper limb injuries are relatively common, concurrent vascular injuries are rare. However, when a major vessel such as the brachial artery is injured, amputation may be required. This loss of a limb can result in PLP. To prevent this, the authors used a unique and rare protocol of Continuous Peripheral Nerve Block (CPNB) in the present case. It not only underscored the importance of intraoperative analgesia in preventing PLP but also proved to be a crucial anaesthetic tool in facilitating the surgery and providing the patient with a more comfortable postoperative recovery.

Kastamonu Bölgesinden Toplanan Kestane Balının Mineral Madde ve Ağır Metal İçerikleri

Chestnut honey, which is known for its apitherapic properties besides its nutritional attributes, is one of the main groups of monofloral honey types. Kastamonu is the most important province because where constitutes two-thirds of the chestnut forest flora of the Black Sea region. Kastamonu Chestnut Honey, produced in apiaries within the chestnut forests, has been registered as a geographical indication and designation of origin. The nutritional value of honey is related to its nutritional and chemical content. Kastamonu chestnut forests have a different distribution with their scattered structure from the coastline to 1000-1200 meters altitude. Therefore, this study was planned with the prediction that chestnut honey produced in different districts has a different composition. The aim of the study is to contribute to official regulations regarding the product, product standardization, and national branding studies by determining mineral and heavy metal contents based on the region where the chestnut honey is produced. As a result of the study, the main concentrations of the elements in the chestnut honey samples were affected by the geographical location, because the apiaries where honey samples were collected in chestnut forests in Kastamonu districts had different altitudes, climates and soil properties, and different secondary flora. The most abundant elements in the samples were potassium (1410.0-6581.5 ppm) sodium (0-204.4 ppm), calcium (125.3-287.5 ppm), and magnesium (24.73-61.88 ppm). Iron (1.32-9.54 ppm), zinc (1.34-20.84 ppm), and manganese (1.39-18.69 ppm) were also found in moderate and others in trace levels. Because manganese is found at moderate levels in all chestnut honey samples and it is found at higher levels than other honey types, it can be recommended that Mn, as fingerprints to detect imitation and adulteration of chestnut honey. While Cd, a heavy metal, was found in only one sample, Ni was not detected in any sample. Whereas Pb concentration varied between 1.84 ppm and 3.38 ppm for the samples, the contents of Al concentrations were quite high (2.94-13.94 ppm). Because there wasn't a maximum limit for heavy metal contents of honey types in the Turkish Food Codex Contaminants Regulation, no evaluation could have been made regarding the suitability of these heavy metal contents. It is thought that heavy metal contamination limits in honey types should be included in the regulations and especially secondary sources such as metallic containers used for storage during handling processes and harvesting of honey for heavy metal contamination should be reviewed.
