Ecohydrological Conditions in Urban Wells and Patterns of Invertebrate Fauna Distribution (Kraków, Poland)

ABSTRACTGroundwaters are threatened by various kinds of contaminants, especially in cities. The results of an ecohydrological analysis (hydrobiological, chemical and geological) conducted in 91 urban wells in Kraków showed their effect on fauna composition and abundance. In 74 wells, the presence of invertebrates, chiefly characteristic for surface water, as well as Collembola was stated. Copepoda were found in 40 wells, whereas Nematoda, Annelida and Diptera larvae were found at over a dozen sites. Microturbellaria, Rotifera, Ostracoda and Amphipoda were present in only a few wells. The aim of this article was to find the patterns of invertebrates' distribution in the wells to further understanding of their relationships with groundwater chemistry and the geological background. This is especially important in light of the anthropogenic pollution occurring in wells and the desired attainment of the good ecological status of groundwater. According to Student's t‐test, the presence of fauna did not depend on the studied environmental factors, whereas Pearson correlations showed that total fauna abundance and Copepoda occurrence positively correlated with water temperature which was higher in the city in comparison to that in rural wells. The value of the Shannon–Wiener index and the number of taxa negatively correlated with the well's depth. High variations of water chemical parameters caused by mixed lithology and hydrogeology as well as spotty contamination may affect the occurrence of fauna.

Environmental assessment of toxic heavy metals and natural radionuclides in irrigation water from Rustenburg, South Africa

Water is a transparent, tasteless and odourless inorganic compound, essential for life and sustainable development. It is important for food and energy production, socio-economic growth, healthy ecosystems and human existence. Global attention is given to water quality monitoring due to the role it plays in human exposure to different kinds of contaminants, including radioactive and toxic contaminants from industrial, agrochemicals, mining and other anthropogenic activities. This work presents the results of measured natural radionuclides and toxic heavy metals in Rustenburg, and their associated non-carcinogenic and carcinogenic risk. The average concentrations of Cd, Cu, Co, Fe, Ni, Mn, Pb and Zn are 0.00007 mg/l, 0.0087 mg/l, 0.0033 mg/l, 0.0636 mg/l, 0.0052 mg/l, 0.0217 mg/l, 0.0003 mg/l and 0.0047 mg/l respectively and are below the safe limit of toxic heavy metals in water. The activity concentration of 40K and 238U ranges from 7.07 Bq/l to 13.2 Bq/l and 1.24 × 10−04 Bq/l to 1.09 × 10−02 Bq/l, with a mean activity concentration of 11.6 Bq/l and 2.78 × 10−03 Bq/l respectively. 232Th was not found in all measured water samples. The estimated average committed effective dose from ingestion of natural radionuclides was observed to be below 170 μSv/yr for 40K, 120 μSv/yr for 232Th and 238U, and a total of 290 μSv/yr reported by the United Nations Scientific Committee on the Effects of Atomic Radiation. The assessment of human health risks resulting from exposure to toxic heavy metals shows negligible carcinogenic and non-carcinogenic health risks to the exposed population, making the water sources from which the sample was collected, safe for agricultural and domestic use. The obtained results will also serve as reference data for future environmental studies.

β-Ketoenamine covalent organic frameworks with abundant carboxyl groups for the efficient removal of malachite green in actual water environments

In this study, imine-based COF (TpPa-2COOH) with abundant carboxyl groups is constructed by 1,3,5-triisopropylchloroglucitol (Tp) and 2,5-diaminoterephthalic acid (Pa-2COOH) via “one-step” approach with solvent stability and resistance to acidity and alkalinity. TpPa-2COOH COF achieves highly efficient malachite green (MG) adsorption with a maximum adsorption of 296.56 mg·g−1 at pH = 5, and the adsorption capacity exceeds many reported adsorbents. Meanwhile, TpPa-2COOH COF shows outstanding adsorption performance to MG, such as 97.67 % removal rate in actual water environments, unique selective adsorption of MG in kinds of contaminants and good adsorption capacity in highly concentrated salt solutions. Additionally, TpPa-2COOH COF shows 78.4 % removal rate after six cyclic desorption-adsorption, demonstrating its excellent recyclability. Furthermore, the processes of monolayer adsorption and chemisorption are confirmed by the isotherms and kinetics of adsorption experiments. The adsorption mechanisms of π-π interaction, electrostatic attraction, hydrogen bonding and channel adsorption are further verified by XPS, EDX, Zeta potential and DFT calculations. This work hopes the synthesis and adsorption application of carboxylated COFs provide new ideas for developing novel adsorbents.

INNOVATIVE TECHNOLOGICAL SOLUTIONS FOR REMOVAL OF PHARMACEUTICAL CONTAMINANTS FROM WATER SOURCES

The waste derived from pharmaceutical products represent a huge worldwide problem. The aim of this paper is to describe, analyze and compare some depollution procedures for such kind of contaminants and to highlight their advantages and disadvantages from various points of view in order to propose concrete cleaning solutions. Classical methods used for contaminant removal from wastewaters in wastewater treatment plants (WTP) and from drinkable water in treatment plants (TP) do not satisfactorily reduce the content of pharmaceutical pollutants (PhP). After an extended analysis of many factors which can be involved in the treatment efficiency, this paper proposes some rehabilitation solutions for existent TP and WTP by adding to the conventional technologies, some operations of advanced treatment. These advanced operations are filtration through semipermeable membranes, i.e., microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), advanced oxidation processes (AOPs), i.e., ozonation, H2O2, adsorption on activated carbon (AC). Statistical procedures are applied to compare these removal methods for such type of pollutants and to prove their efficacy. In this context, it is demonstrated that multivariate statistical techniques, combined with water quality indices represent a viable combination to perform accurate monitoring and spatiotemporal analysis of water quality assessment. This work presents concrete solutions for TP rehabilitation in order to comply with regulations in force related to PhP.

Preparation of polystyrene and silane-modified nano-silica superhydrophobic and superoleophilic three-dimensional composite fiber membranes for efficient oil absorption and oil-water separation

Oily solid waste and wastewater are two kinds of contaminants that seriously endanger the environment and the general public. Recently, superhydrophobic and superoleophilic materials have attracted extensive attention owing to their exceptional oil-water separation capabilities. In this study, we demonstrated a simple, low-cost, and high-economic efficiency method to prepare nanosilica (SiO2) from dye diatomite filter aid waste (DDW) and silanize it with octadecyltrichlorosilane (OTS) to form hydrophobic nanosilica (hSiO2) by solution impregnation. Polystyrene/hydrophobic nanosilica (PS/hSiO2) composite fiber membranes with a rough surface and low surface energy were prepared by electrospinning. The prepared PS/hSiO2 water contact angle can reach 166.6°, showing superhydrophobicity and excellent adsorption capacity for various common oils. The maximum oil absorption capacity for transformer oil can reach 136.4 g/g. Importantly, the oil absorption process of the nanocomposite is selective, fast, and efficient, and it can be used for the purification of oil-contaminated water. In addition, it also demonstrates remarkable durability and stability in strong acid and alkali solutions. This strategy of making oil-water separation materials from solid waste may offer a straightforward, cost-effective, and environmentally sustainable option for the treatment of solid waste, industrial oil wastewater treatment, and marine oil spill cleanup.

AN OVERVIEW ON THE SYNTHESIS OF PHOSPHORYLATED CHITOSAN DERIVATIVES FOR THE ADSORPTION OF EMERGING CONTAMINANTS IN WATER

Safe water for human consumption and for aquatic life is of paramount importance. The emergence of new kinds of contaminants like surfactants, pharmaceutical drugs, hormones, foods and additives, laundry detergents, etc., are posing new and serious challenges to the conventional primary and secondary waste water treatment, because of the inability to remove or degrade these toxic pollutants efficiently and hence, the need for cost effective tertiary treatment method. Adsorption is a promising method worldwide for the removal of emerging contaminants, since it is highly-efficient and has a simple operating system. This review seeks to investigate the suitable preparation methods of soluble phosphorylated chitosan derivatives as efficient adsorbent for effective removal of emerging contaminants in water. Hence, the goal of this study, is to review some synthesis of the phosphates of chitosan under various chemical conditions to produce soluble chitosan derivatives which can be effectively used for the removal of emerging contaminants in water by adsorption technique.

SiO2/WO3/ZnO based self-cleaning coatings for solar cells

The accumulation of pollution and any kinds of contamination on the glass cover of the solar cell affects the efficiency of the photovoltaic (PV) systems. The contamination on the glass cover can absorb and reflect a certain part of the sunlight irradiation, which can decrease the intensity of the light coming in through the glass cover. With the study, it was planned to develop self-cleaning coatings for the PV systems. It was aimed to prevent or reduce the contamination-induced efficiency loss of the existing PV systems. In the scope of the project, SiO2/WO3 and SiO2/WO3/ZnO composites were coated from their solutions on the glass substrates using a dip-coating technique. WO3 was selected as a photocatalyst semiconductor. Under the UV light irradiation, WO3 could absorb the photons of the UV light, generating the photoinduced charge carriers. The photoexcited charge carriers provide both the photoinduced hydrophilicity on the surface of the coating and the photocatalytic degradation of the organic contaminants accumulated on the surface of the coating, which allows water droplets to spread and flow on the surface of the cover glass to remove the contaminations. However, the recombination rate of the photoexcited charge carriers on the WO3 film was high. In order to suppress the recombination of the photoinduced charge carriers, WO3 was coupled with SiO2 and ZnO. Both of these semiconductors improved the photocatalytic activity of the WO3 film. Although SiO2 has superior features in terms of the light transmission, it was not very effective under UV light as a photocatalyst alone. The widely preferred photocatalyst ZnO was added into the composite film structure to enhance the photocatalytic activity. The self-cleaning mechanism of the film coatings on a solar cell was investigated through the photocatalytic dye removal efficiency on the as-prepared film samples. There was a slight decrease in the light transparency and the solar cell efficiency because of the WO3 content of the composite film. On the other hand, coupling the SiO2/WO3 film with ZnO enhanced the photocatalytic activity, and it suppressed the reduction effect of the WO3 phase on both the light transparency and the solar cell efficiency. The photocatalytic dye removal efficiency was increased to over 90% after 240 min of UVA light irradiation. In addition, the solar cell coated with the SiO2/WO3/ZnO film provided almost the same solar cell efficiency as the uncoated solar cell. The water contact angle measurement also exhibited the photocatalytic degradation of the model contamination on the glass cover of the solar cell under the UVA light irradiation.Graphical

An efficient and general oxidative magnetization for preparation of versatile magnetic porous biochar at low temperature

Oxidative magnetization is an emerging method for manufacturing versatile magnetic biochar at comparatively low pyrolysis temperature, benefiting to reducing functional groups decomposition with low energy consume. A magnetic porous biochar was manufactured by a novel oxidative magnetization [KMnO4/Fe2(SO4)3 accelerated pyrolysis of kelp at 300 °C] for removing three kinds of contaminants from aqueous solution. Spherical nanoscale Fe3O4 was massively doped with introduction of oxygen functional groups simultaneously. Remarkable increase of surface area and pore volume was also observed. Benefiting from these factors, remarkably increased adsorption capability and saturation magnetization were achieved. The magnetic biochar possessed 145.71, 72.58, and 322.48 mg/g maximum adsorption amounts for Cr6+, methylene blue, and tetracycline with 17.11 emu/g saturation magnetization, respectively, in which nanoscale iron oxides and oxygen functional groups made significant contributions. Furthermore, KMnO4/Fe2(SO4)3 accelerated pyrolysis showed superior generality for fabricating high-performance magnetic biochars using diverse bio-wastes at low temperature.

Impact of Ecological Factors on Water quality goals

A deeper knowledge of the processes that influence environmental elements in areas such as water management, consumer services, water reuse acceptability, and risk communication, among others. Also, as a result of the unique climate, soil features, and agricultural idiosyncrasies, water quality and water management for human welfare and the natural environment. Also, various kinds of contamination may also have an impact on aquatic habitats across the world. Trace metals are one of the most major pollutants that have harmed marine environments. Its release into the marine environment is caused by both natural and human activities. Erosion and pollution are two of the negative repercussions of agricultural operations on soil quality. Pollution from nutrient leaching and intrusion is one of the consequences for water resources. To choose the best long-term solutions for mitigating these effects, researchers should focus on developing an accurate water and soil quality monitoring system at many scales based on a functional evaluation. On the other hand, the review focuses on the influence of metals and nutrients on water quality for water usage and its impact on agricultural output. Its mean water quality great impact on natural and human on the other hand effect on environment and ecosystem. finally this review indicated that many ecological factors positive effects on water quality goals.

Synergy between UV light and trichloroisocyanuric acid on methylisothiazolinone degradation: Performance, kinetics and degradation pathway.

Methylisothiazolinone (MIT) is widely used in daily chemicals, fungicides, and other fields and its toxicity has posed a threat to water system and human health. In this study, ultraviolet (UV)/trichloroisocyanuric acid (TCCA), which belongs to advanced oxidation processes (AOP), was adopted to degrade MIT. Total chlorine attenuation detection proved that TCCA has medium UV absorption and a strong quantum yield (0.49 mol E−1). At a pH of 7.0, 93.5% of MIT had been decontaminated after 60 min in UV/TCCA system (kobs = 4.4 × 10−2 min−1, R2 = 0.978), which was much higher than that in the UV alone system and TCCA alone system, at 65% (1.7 × 10−2 min−1, R2 = 0.995) and 10% (1.8 × 10−3 s−1, R2 = 0.915), respectively. This system also behaved well in degrading other five kinds of contaminants. Tert-butanol (TBA) and carbonate (CO32−) were separately used in quenching experiments, and the degradation efficiency of MIT decreased by 39.5% and 46.5% respectively, which confirmed that HO• and reactive chlorine species (RCS) were dominant oxidants in UV/TCCA system. With TCCA dosage increasing in a relatively low concentration range (0.02–0.2 mM) and pH decreasing, the effectiveness of this AOP system would be strengthened. The influences of coexisting substances (Cl−, SO42−, CO32−, NO2− and NO3−) were explored. MIT degradation pathways were proposed and sulfur atom oxidation and carboxylation were considered as the dominant removal mechanisms of MIT. Frontier orbital theory and Fukui indexes of MIT were employed to further explore the degradation mechanism.

Hemicellulose-g-PAAc/TiO2 Nanocomposite Hydrogel for Dye Removal

Dyes pollution on urban environment is of great concern because of the human health hazards associated with this kind of contaminants, and the use of low-cost photocatalytic composite material is an efficient treatment method to minimize the environmental impact. A novel hemicellulose-g-PAAc/TiO2 composite hydrogel was prepared as a promising alternative material for dye removal. Wheat straw hemicellulose and TiO2 nanoparticles were first modified and then incorporated into hydrogel via covalent bonds. Effects of gel dosage, pH, initial concentration and contact time on the adsorption amount of methylene blue were systematically studied using the prepared hydrogel. The equilibrium adsorption data was fitted well to the Freundlich isotherm model, and Langmuir isotherm analysis indicated that the adsorption capacity of the hemicellulose-g-PAAc/TiO2 composite hydrogel was 389.1 mg/g, and adsorption kinetic study showed that the adsorption process can be described by the pseudo second-order kinetic model. The prepared composite hydrogel exhibited high photodegradation ability for methylene blue under alkaline conditions, and all results indicated that the hemicellulose-g-PAAc/TiO2 composite hydrogel had excellent photocatalytic degradability for dyes, which can be used in practical process.

Expert Kaplan–Meier estimation

ABSTRACT The setting of a right-censored random sample subject to contamination is considered. In various fields, expert information is often available and used to overcome the contamination. This paper integrates expert knowledge into the product-limit estimator in two different ways with distinct interpretations. Strong uniform consistency is proved for both cases under certain assumptions on the kind of contamination and the quality of expert information, which sheds light on the techniques and decisions that practitioners may take. The nuances of the techniques are discussed – also with a view towards semi-parametric estimation – and they are illustrated using simulated and real-world insurance data.

Durable Biomimetic Two-Tier Structured Superhydrophobic Surface with Ultralow Adhesion and Effective Antipollution Property.

Superhydrophobic surfaces with low adhesion have attracted great attention in recent years owing to their extensive applications. Enlightened by multifunctional rice leaves, a micro/nanobinary structured superhydrophobic surface was successfully fabricated on the Ti6Al4V substrate by photoetching, acid etching, alkaline etching, as well as fluorination treatments. Water droplets exhibited a Cassie impregnating wetting state on this superhydrophobic surface, under which the contact area fraction of the liquid-air interface caused by primary micron-scale stripped bumps (fp) and secondary nanoflower-like structures (fs) were calculated for the first time. The water adhesion force of this nonwetting surface was precisely measured as 7 μN, which was much lower than that (362 μN) of the original flat substrate and the previous reported surfaces. Moreover, this low-adhesive surface displayed good chemical stability after exposing to air, soaking in aqueous solutions (acid, alkaline, and salt), and cyclic icing/melting treatment. It also showed good mechanical durability after a series of abrasion treatments. Besides, this multifunctional superhydrophobic surface exhibited superior antipollution property to different kinds of contaminants. This multifunctional superhydrophobic surface displays a huge potential for industrial droplet transportation and self-cleaning applications.

Detection of Soil Contamination Using Electrical Resistivity Tomography and Induced Polarization Methods By Tank Model

Resistivity and induced polarization surveying were originally developed for mineral exploration but are now the of outcome new applications in the field of environmental and engineering geophysics. This paper describes an experimental setup used to carry out resistivity tomography and induced polarization tests (in the time domain) that are used in geological and geophysical surveys to characterize soil and rock. The test setup is carried out in the laboratory via the Tank model developed for this purpose. The paper describes a laboratory system used to study the influence of different contaminants in a small-scale soil stratum using two geophysical methods and describes how the behaviors of resistivity and chargeability result in contaminated and uncontaminated soils. The results of a geophysical survey were performed to identify a contaminator in the Tank model. Both techniques provided evidence of contamination. In general, the electrical resistivity method was better than the induced polarization method in providing distinct values for most kinds of contamination, Except for the contamination with salt water, both methods gave significant results.

Ultrasonic Preparation of Coating Surfaces

For various methods of obtaining coatings, the general stage of technology is the preparation of the surface for the application of the coating material. The properties of the resulting coating directly depend on the quality of preparation. In the process of obtaining coatings, the most common application of ultrasonic treatment to clean the surface from all kinds of contaminants. However, with a sufficient intensity of processing, ultrasound has a significant effect on the geometric properties of the surfaces of products. Prolonged cavitation action leads to changes in the roughness and sub-roughness of the metal surface. The article discusses the effectiveness of the use of ultrasonic liquid treatment in the preparation of surfaces for coating. The results of studies on the effect of cavitation on the change in roughness, sub-roughness and oil absorption are presented. Revealed an improvement in the adhesion properties of surfaces after ultrasonic liquid treatment.

IOT sensor-based pollution management control technique

Environmental pollution generates heart muscle difficulties, breathing difficulties, and other medical problems affecting human civilization. The purpose of this paper was to offer a comprehensive resolution to the issue of pollution in modern civilization, which will enable us to track and address significant issues with general health, societal issues, and environmental problems. The proposed methodology seems to be an IoT unit in dealing with all these concerns, which includes effectively using various sensors to gather predictions of different kinds of contaminants on the earth. Present information on a website uses various sensors to gather estimates of various types of toxins in the earth and present information on a website that is accessible to everyone without charge. The devices and sensors that are installed at various points around us provide the research information. After gathering information from sensors, a comparison of the information is made using the Centralized Pollution Control Committee (CPCC). The proposed approach aids in reducing the pollution in the modern atmosphere, and as a result, pollution can indeed be decreased by making significant progress in that direction. Our proposed approach makes it possible for everyone in civilization to periodically measure and evaluate the quantity of pollution in their surroundings, a practice that leads inevitably to healthcare, ecological, as well as other social and economic problems.

SURVEY OF Salmonella spp and E. coli IN DRINKING WATER OBTAINED FROM SOME SELECTED LOCAL GOVERNMENT AREAS IN ADAMAWA STATE, NIGERIA

The aim of this research is to determine some bacteriological composition in drinking water (wells and bore-holes) at Mubi-north, Girei and Mayo-Belwa local government areas of Adamawa state, Nigeria. Various types of bacteria/viruses are categorized as pathogens, disease causing organisms that can be found in pretreated or inadequately treated water. Water, being dynamic, needs to be constantly analyzed to minimize contaminants that could be detrimental to the consumers. E. coli and fecal coliform are bacteria whose presence can indicate water contaminated by human or animal wastes, causing short-term health effects. When there is seepage of contaminant through well casing, cracks or holes in the well casing allow water that has not been filtered through the soil to enter the well. This seepage is common in the wells made of concrete, clay tile, or brick. These are the nature of wells commonly found across the study areas. Most of the bole holes are hand dug, shallow, located close to river banks where refuse and farming activities characterized by bush burning, application of fertilizers, animals and human defecation is the order day due to these reasons, water sources across the study areas are vulnerable to different kinds of contamination. Investigation into water quality is not a relatively new phenomenon but literature concerning the quality of drinking water from the study is sparse. 62 water Samples were collected at random from both well and boreholes at different location within the study areas using containers with earlier prepared nutrient broth. Three different media were prepared adhering strictly to the media manufacturer’s instruction. For the determination of E. coli, 24g of EMB was used and SS agar was used for Salmonella species. Results shows that in well water during rainy season the mean concentration of salmonella spp. ranged from (153– 272 CFU/ml), Total coliforms, well water during rainy season mean concentration ranged from (418 – 624 CFU/ml), During dry season, values ranged from (81 – 126 CFU/ml), while for E.coli, in well water during rainy season, the mean values ranged from (33 – 71 CFU/ml),. During dry season ranged from (97. – 131 CFU/ml), conclusively, findings indicates significant higher bacteriological composition in well water during rainy season than dry season (p<0.05). Hence, calls further research and monitoring.

Experimental Evidence for Manure-Borne Bacteria Invasion in Soil During a Coalescent Event: Influence of the Antibiotic Sulfamethazine

The fertilization of agricultural soil by organic amendment that may contain antibiotics, like manure, can transfer bacterial pathogens and antibiotic-resistant bacteria to soil communities. However, the invasion by manure-borne bacteria in amended soil remains poorly understood. We hypothesized that this kind of process is both influenced by the soil properties (and those of its microbial communities) and by the presence of contaminants such as antibiotics used in veterinary care. To test that, we performed a microcosm experiment in which four different soils were amended or not with manure at an agronomical dose and exposed or not to the antibiotic sulfamethazine (SMZ). After 1 month of incubation, the diversity, structure, and composition of bacterial communities of the soils were assessed by 16S rDNA sequencing. The invasion of manure-borne bacteria was still perceptible 1 month after the soil amendment. The results obtained with the soil already amended in situ with manure 6 months prior to the experiment suggest that some of the bacterial invaders were established in the community over the long term. Even if differences were observed between soils, the invasion was mainly attributable to some of the most abundant OTUs of manure (mainly Firmicutes). SMZ exposure had a limited influence on soil microorganisms but our results suggest that this kind of contaminant can enhance the invasion ability of some manure-borne invaders.

The role of nutrients in severe acute respiratory syndrome coronavirus 2 infection

Balanced and healthy nutrition is a vital to attain a good immune response. Numerous studies have reported that boosting up adaptive immunity through nutritional interventions can impede viral infections. With the present leading challenge of the COVID-19 pandemic globally, maintaining good nourishment is indispensable to remain immune against the novel virus. By and large, ineffectively fed people are at a higher risk of creating different kinds of contaminations. In addition, constant and extreme contagion can cause health problems and demolish a patient’s nourishing status, making them susceptible to different diseases. During the COVID-19 pandemic, everyone must screen their eating routine and nourishing status. Good nutrition can subside the ongoing unprecedented health complications and deaths. Evaluating the clinical status of COVID-19 cases at the hour of clinic confirmation is strongly recommended. Specific dietary help is prescribed to be given to those in the high-hazard bunch, asymptomatic transporters, and patients with moderate or extreme COVID infection. An assortment of micronutrients techniques to treat COVID-19 can prove beneficial at the preliminary stage of the clinical attendance. The prompt supplementation of specific supplements in gentle cases can forestall the movement of sicknesses.
