Comparative Analysis of Heavy Metal Content in Impacted Third Molars from Industrial and Non-Industrial Areas and Its Effect on the Isolation, Culture, and Proliferation of Dental Stem Cells (DSCs).

Background: This study investigates the impact of environmental pollution on the quality and viability of dental stem cells (DSCs) from impacted third molars. By comparing DSCs from patients in industrial areas with high air pollution and those from non-industrial regions, the research assesses the adverse effects of heavy metals on stem cell proliferation. Methods: Impacted lower third molars were collected from 28 patients-10 from industrial and 18 from non-industrial areas. Patients were divided into two age groups: 18-27 years and 28-38 years old. Dental pulp was extracted under sterile conditions, and DSCs were isolated and cultured. Heavy metal concentrations in dental tissues were measured using atomic absorption/emission spectrometry. Results: The study found significantly higher concentrations of copper and lead in the dental tissues of patients in industrial areas. Cell viability was lower in samples from these areas, with a statistically significant difference in average doubling time and the number of cells obtained after the first passage. There was no significant impact of gender on heavy metal content, except for higher iron levels in men. Conclusions: Exposure to industrial pollutants negatively affects the viability and proliferation of DSCs, but there are no differences in differentiation in the osteogenic medium regarding cell mineralization. These studies highlight the importance of environmental factors for oral health, suggesting that residents of polluted areas may face greater difficulties in dental and regenerative treatments. Further research is needed to develop strategies to mitigate the effects and improve clinical outcomes for affected populations.

115 years of sediment deposition in a reservoir in Central Europe: Effects of the industrial history and environmental protection on heavy metals and microplastic

AbstractHumans have considerably influenced accumulation rates and sediment composition in lake deposits. Due to near‐continuous accumulation, lakes and reservoirs are an excellent archive of these anthropogenic influences. The Urft Reservoir in the Eifel Mountains, western Germany, provides a unique record of the human influence on the landscape for the past 115 years. In 2020 and 2021, 24 cores and 23 surface samples were obtained from the bottom of the, by that time drained, reservoir. Grain size, heavy metals, weathering signatures and microplastic were analysed. For the chronology, caesium‐137 and microplastic were used. Using the first occurrence of microplastic as well as different plastic types for dating was not successful. However, a distinct layer with a high number of microplastic particles could be traced back to a fire in 1991 and was used as an additional stratigraphic marker in the age‐depth model. A period of relatively high accumulation rates in the reservoir occurred in the mid‐1950s and was related to enhanced construction works in the local valleys. Analysis of heavy metal content in the reservoir sediments shows a strong connection to historical changes in ore industry in the valley of the Urft. Stricter environmental protection laws and the decline of the metal processing industry resulted in a reduced input of lead, copper and zinc in the reservoir until the mid‐1980s. Since then, heavy metal content has remained relatively constant. A major flooding event in July 2021 did not lead to the remobilisation of older contaminated deposits as indicated by low heavy metal content in flood deposits. Accordingly, also the microplastic content is not increasing following the extreme event. Due to the degree of weathering of the flood deposits, it is argued that mainly hillslope material was transported into the Urft and subsequently into the Urft Reservoir during this event.

Comparative analysis of heavy metal content of unregulated facial whitening creams and branded facial whitening creams

The present study was conducted to evaluate potential health risks of Omani cosmetics considering the dangers and adverse effects on health caused by unregulated and unlabelled cosmetic products. Therefore, this current study is to examine the toxic heavy metals of unregulated facial whitening creams that are available in the Omani market and compare them with branded facial whitening creams. A total twenty-two samples were purchased from the Souqs/markets of all eleven governorates of Oman and their heavy metals content was determined by using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). The sample was digested by using ultra wave microwave at 180 °C. The percentage of heavy metals present in the unregulated whitening creams were compared with the heavy metals content of two randomly selected and branded whitening creams. The results showed that most of the unregulated samples contain significant amount of chromium, cooper and lead. In comparison, the branded face creams contained only the permissible amount of the heavy metals tested. The maximum arsenic content was found in a sample collected from Al Batinah South region (1.74 ppm). The maximum cadmium content was found in a sample collected from Al Wusta region (2.02 ppm). The maximum cobalt and chromium content were found in the samples collected from Al Buraimi region (0.10 ppm) and Dhofar region (8.04 ppm) respectively. In conclusion, unregulated face creams are not safe for human consumption because they contain significant levels of heavy metals that exceed the permissible limits.

Analysis of Lead (Pb) and Cadmium (Cd) heavy metals in cow’s milk in Central Java, Indonesia

The need for animal food is increasing because of its nutritional content. Foodstuffs needed to meet daily needs must be healthy and free from harmful substances, including heavy metals. Fresh cow’s milk is an animal-based food that is consumed by many people because it is very easy to find at an affordable price. This study aimed to determine the levels of heavy metals Pb (Lead) and Cd (Cadmium) contained in fresh cow’s milk and to find recommendations if they exceed a predetermined threshold. The method used is laboratory analysis of heavy metal content in fresh cow’s milk from a cattle farm in Boyolali Central Java. Analysis of Pb and Cd content was carried out by Atomic Absorption Spectroscopy (AAS). Data analysis was carried out by comparing the content of heavy metals in fresh cow’s milk with SNI 3141.1: 2011 concerning quality requirements for fresh cow’s milk and SNI 7387: 2009 concerning the maximum limit of heavy metal contamination in food. Laboratory test results on fresh cow’s milk had a heavy metal Pb content of 96.67 mg/kg and a heavy metal Cd content of 4.45 mg/kg. It is known that the maximum limit for heavy metal contamination in food is 0.02 mg/kg. It can be concluded that the heavy metal content in fresh cow’s milk has exceeded the existing quality standard threshold. Previous research revealed that the metal lead content in cow’s milk that has been processed is lower than in cow’s milk that has not been processed.

КАРАТОМАР СУ ҚОЙМАСЫНЫҢ ЖАҒАЛАУ АЙМАҒЫНЫҢ ТОПЫРАҚТАРЫНЫҢ АГРОХИМИЯЛЫҚ ҚАСИЕТТЕРІН ЗЕРТТЕУ: АГРОХИМИЯЛЫҚ ТАЛДАУ ЖӘНЕ ҚОРЫТЫНДЫЛАР

The assessment of the main agrochemical indicators of the quality of agricultural soils adjacent to the Karatomar reservoir, such as pH, humus, mobile and total phosphorus and potassium, nitrogen, nitrates, mobile sulfur, heavy metals, was carried out. The determination of agrochemical indicators of soils was carried out in accordance with the regulatory requirements and standards of the Republic of Kazakhstan and state and foreign scientific recommendations; the research work was carried out from autumn 2023 to winter 2024. It has been established that the agricultural soils adjacent to the Karatomar reservoir are characterized by an alkaline environment with a pH above 7.0, which significantly affects the absorption of nutrients by plants. The humus content is at a moderate level; however, the low levels of nitrogen in nitrate form and available phosphorus indicate potential limitations for photosynthesis and overall plant viability. The high concentration of available potassium contributes to plant stress resistance. The analysis of heavy metal content showed that overall levels comply with standards, but the identified exceedance of cadmium levels requires attention when developing measures to improve soil quality and ensure the environmental safety of the region.

The effect of adding wood and temperature on the carbonization of chicken manure and the properties of biochars

The paper presents characterization of chicken manure and mixture of chicken manure (CM) and beech wood (WB) carbonization at 450 and 600 °C. Experiments were carried out in small scale batch reactor. The obtained results indicate that increase in the amount of beech wood in the pellets caused increase in fixed carbon content and also affected increase in the calorific value of biochar. The results show that biochar obtained in the carbonization process of chicken manure cannot be used for the barbecue charcoal production, which is caused by low Cfix and high ash content. Because of this, adding wood may be a good solution for the carbonization process. Experimental investigation showed that carbonization of pellets consisting of CM50 % and CM25 % lead to obtained biochar which meets standards for briquette barbecue production. Experimental results showed the possibility of using pyrolysis gases for energy purposes. Carbonization in different temperatures lead to production of pyrolysis gas mixtures with calorific value higher than the energy demand of the process. Moreover obtained energy contained in gases can cover the part of the heat demand of the farm. Analysis of heavy metals content showed that biochars meet the standards defined by the International Biochar Initiative.

Education is a right to every child, but Sokoto is suffering from many issues ravaging education, therewith, a major issue is the Almajiri school. Because the Almajiri schools are abandoned there is every tendency that their drinking water is contaminated considering the rising pattern of pollution across the globe. The aim of the study was to carry out an analysis of heavy metal content in well water and propel some predictive insights for students well-being in Almajiri schools in Sokoto, Nigeria. Samples of well water were collected from Almajiri schools in Sokoto state and metals were analyzed using atomic abortion spectroscopy. 60.10 ± 5.1 to 600.1± 0.01, 100.1 ± 0.5 to 600.0 ± 0.02, are the ranges of calcium, and magnesium macroelements determined. The ranges for essential heavy metals zinc, and iron are as follows; 2.34 ± 0.05 to 5.00 ± 0.02 (zinc), and 0.54± 0.05 to 10.43 ± 0.5 (iron) respectively. The ranges of Pb, Hg, and Cd assessed are as follows: lead (0.0 to 1.06 ± 0.005), mercury (0.10 ± 0.002 to 2.501 ± 0.01), and cadmium (0.00122 ±0.0004 to 0.0761 ± 0.0001). The HI for the heavy metals determined are in the order of schools B>D>A>C. The metals determined are either excess or little (with respect to essential heavy metals) in many cases. In one school, the HI is far above 1 and therefore risk the population with effects. Thus, can elicit harm to the consumers. They can affect the academic, cognitive capacity of the Alamjiri children. There is need to take proper measures to save the health and future development of the Almajiri child against heavy metals poisoning possibility. Â

Study of Heavy Metal Content in Lola Snail (Trochus niloticus) in The Karang Island of Central Tapanuli Regency

Research on the analysis of heavy metal content in the waters of Karang Island, Central Tapanuli Regency aims to know the metal content in Lola Snail meat, sediment, and Lola Snail shells. The research method begins with taking samples of Lola snails and sediments on Karang Island and preparing the samples. Then, the samples were analyzed by AAS (Atomic Absorption Spectrometry) to determine the content of heavy metal elements in the meat of Lola Snail, followed by XRD (X-Ray Diffraction) testing to determine the content of heavy metal elements in sediments, and also testing with EDX (Energy Dispersive X-Ray) to determine the content of heavy metals in the shell. The results of the analysis on the AAS test showed that the order of heavy metal concentrations in Lola snail meat at station I was Zn Cr Cu Cd Pb, while at station II was Zn Cu Cr Cd Pb. The results of the sequence of heavy metal concentrations using XRD in sediments around Karang Island at the station I was Zn Cr Cu Cd Pb, while at station II was Zn Cd Cu Cr Pb. The results of the analysis on the shells of Lola snails using EDX at both stations showed they did not contain heavy metal elements (Pb, Cd, Cu, Cr, and Zn), but only contained O, Ca, Mg, Na, Al, and Si elements.

Screening of new native metallophytes from copper abandoned mining site: Promising tool for phytoremediation

AbstractA field survey on abandoned mining site ‘Bir Nehass‐Morocco’ was conducted to identify new native metallophytes as a promising tool for phytoremediation. The spatial distribution of metals in tailings and mining soils was investigated and metal accumulation in plant tissues was analyzed and compared. The results indicated that the studied area was polluted by Cu, Zn, Pb and Cd Cadmium with maximum values of 2892, 27868.3, 6982 and 63.03 mg.kg−1, respectively, which are higher than background levels for agricultural soils. The concentrations of Cu, Zn, Pb and Cd decreased with the distance from the mine tailings. Thirteen species (11 families) were identified and mainly native and therophyte plants. Significant difference (p < 0.05) was observed among the average concentrations of metals in plant tissues and most values exceeded the normal concentration range. Based on the comparative analysis of heavy metals content, translocation and bioconcentration factors in plants, Aizoon canariense L, Hirschfeldia incana (L.) L. Fossat, Citrullus colocynthis (L.) Schrader and Peganum harmala L had a high accumulation ability and showed a remarkable phytoremediation potential which could be identified as promising candidates for phytoremediation techniques.

Analysis of heavy metals content in commercially available kratom products in Richmond, Virginia

Kratom is a novel psychoactive substance that has gained popularity within the past ten years. Originating from Southeast Asia, the leaves of the Mitragyna speciosa tree contain two principal alkaloids, mitragynine and 7-hydroxy-mitragynine, that play a key role in opioid-like effects. Due to its effects, the use of kratom products has increased drastically. However, reports describing concerns about the heavy metal content of these products for safe consumption are still scarce. i Twenty-seven kratom products were obtained from tobacco shops in the Richmond, Virginia area, including powders, teas, extracts, and a carbonated beverage. Kratom samples were subjected to an acid digestion followed by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) analysis. Aluminum (Al), arsenic (As), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), nickel (Ni), and lead (Pb) were quantitated using yttrium as the internal standard. Kratom tea samples were found to have up to 20 times the tolerable upper intake of manganese. Overexposure to manganese can lead to manganism, a syndrome that presents Parkinsonian symptoms including tremors, dystonia, and facial muscle spasms. As kratom products become more mainstream, stricter regulations of these products must be set in place. The presence of toxic metals in kratom products is a public health concern.

Multivariate analysis of heavy metals content of beef from Soroti, Uganda.

Information about food hygiene and quality in the sub-Saharan African countries remains scarce at a time when many of their citizenry are beginning to acquire the much coveted middle income status. Confounding this are challenges linked to monitoring on a continuous basis the safety of food produced by such lucrative industries as the beef industry. The objective of the current study was to initiate a process of encouraging changes in the status quo, by showing how a first step in that direction might look like. Using heavy metal contents of representative beef samples from butcheries in Soroti, Uganda, typical of a sub-Saharan country, we demonstrate how relationships and common sources of metals in food could be identified in a multivariate space. Beef samples from 40 sites were analyzed by atomic absorption spectrometry for iron (Fe), zinc (Zn), nickel (Ni), chromium (Cr), lead (Pb), copper (Cu), cobalt (Co) and cadmium (Cd). The study showed that all beef samples contained these metals, the extent of which were in the order: Fe>Zn>>Ni, Cr>Pb>Cu, Co>Cd. By correlation analysis, the pairs Ni and Cr, Cd and Co, Ni and Fe or Cr and Fe were found to be most likely coming from similar sources. At least three distinct characteristics of beef consumed in Soroti were also found, a distinction perhaps arising from three major categories of feedlots used to raise donor cattle. The incremental risk of children or adults developing cancer over a lifetime was estimated and found to fall into three categories, two of which are separately explained by the presence of Cr or Ni. The sources of these metals remain a matter of speculation on our part. More studies are needed to determine these sources and to understand the nature of cancer risk in the three categories of beef identified here.

Isolation and Analysis of Heavy Metal Content in Scales from Three Species of Farmed Fish in Lake Maninjau

The study isolated and analyzed heavy metal content in fish scale from Osphronemus goramy, Cyprinus carpio, and Oreochromis niloticus in Lake Maninjau. Fish weights (n=10) for O. goramy, C. carpio, and O. niloticus were 389.99±24.96 g, 633.30±87 g, and 210.5±12.12 g. Isolation begins with washing scales using running water, followed by 24-hour immersion in 10% NaCl (1:10 w/w) in a refrigerator. Afterward, they are oven-dried at 50°C for 3.5 hours and ground into powder. Fish scale results were analyzed using the dry weight/wet weight formula x 100. AOAC-compliant spectrometry tested heavy metal concentrations of Hg, Pb, Cr, As, Ag, and Cu. Results for O. goramy, C. carpio, and O. niloticus were 65.85%, 61.68%, and 55.63%, respectively. The concentration of heavy metals in O. goramy showed the highest level was Pb (185 mg/kg), followed by Cu (83 mg/kg), Ag (<14.66 mg/kg), Cr (<5 mg/kg), Hg and As (0.43 mg/kg). In C. carpio the highest concentration was Pb (152 mg/kg), followed by Cu (121 mg/kg), Cr (50 mg/kg), Ag (15 mg/kg), Hg and As (<0.50 mg/kg). Meanwhile, in O. niloticus, the highest concentration was Cu (160 mg/kg), followed by Pb (149 mg/kg), Cr (50 mg/kg), Ag (15 mg/kg), Hg and As (< 0.50 mg/kg).

Monitoring and analyzing the effect of heavy metals in air based on ecological and health risks in Coimbatore

Earlier, there were limited number of small-scale factories and they were operated only for certain hours a day. Therefore, the level of air pollution was moderate. But when those factories are converted into a large-scale factory the industrial air pollution created a major impact. The studies say that 6 out of 10 people in Coimbatore region inhales polluted air that outdo the WHO data limit. Air quality index can convey the people how polluted the air is. Industries are the major source for worsening air quality. Higher the air quality greater the health concern. To estimate the air quality in the industrial areas of Coimbatore city the air pollutants like ammonia (NH3), Nitrogen dioxide (NO2), Particulate matter 2.5 (PM2.5), Sulphur dioxide (SO2), Particulate matter10 (PM10), Carbon mono oxide (CO) and Trioxygen (O3) are monitored regularly to do the analysis and also the suspended particulate matter (SPM) are collected in the industrial areas of five stations. The collected SPM undergoes analysis for heavy metal contents like Zinc (Zn), Ferrous (Fe), Copper (Cu), Lead (Pb), Nickel (Ni) and Chromium (Cr). All the ten samples were wrapped in a polythene sleeve and taken to air pollution division, Environmental Scientific Research Department, Government college of Technology, Coimbatore.The result shows that the prominent pollutant present in Coimbatore city is Carbon monoxide (CO) and also the higher possibility of Particulate matter10 (PM10). In heavy metal content analysis, the result shows that the concentration of zinc (Zn) is greater than that of other metal contents in Coimbatore city. The order for concentration of heavy metals that we got from our analysis is Zn>Cu>Fe>Cr>Ni>Pb.The concentration of Zinc (Zn) is higher because in most of the industries iron and steel plays a major role. Zinc (Zn) act as protective coating for those products.Air pollution is one of the deadly environmental threat for death. It is accountable that the death from heart attacks, strokes, breathing disorder and other respiratory disease are more than 7 million for every year. This states that the death due to air pollution causing diseases are greater than tuberculosis, AIDS and malaria combined. As per the medical analysis the causes of cardiovascular and respiratory diseases are mainly due to the heavy metal content present in the air.
