Summary: Moderate arsenic exposure from smokeless tobacco products can lead to health problems. This study used atomic absorption spectroscopy to measure arsenic content in smokeless tobacco products and developed a framework for calculating average daily arsenic intake for different types of smokeless tobacco. Various probability density function fits were used to estimate population risk, and deterministic and probabilistic cancer risk were quantified. The results showed that chewing tobacco and snuff tobacco consumers have higher cancer risk levels compared to dipping tobacco consumers.

Summary: The health risk associated with metal pollution is a global concern due to potential bioaccumulation, toxicity, and carcinogenicity. A study was conducted on over a thousand fish individuals along the heavily sediment-laden Yellow River to investigate metal bioaccumulation and evaluate the health risks to humans. The concentrations of most metals in fish were influenced by trophic levels and the metal content in the aquatic environment. Consumption of fish from the Yellow River does not pose a noncarcinogenic risk to adults and juveniles, but there are carcinogenic risks associated with Cr, As, Cd, and Pb, albeit within acceptable levels. To minimize these risks, adjustments in diet and reducing consumption of aquatic products from the Yellow River are recommended.

Summary: Elevated pCO(2) levels are predicted to decrease the bio-toxicity of arsenic on marine primary producers, but the response may decrease after long-term adaptation. Diatoms evolved arsenic detoxification strategies under high pCO(2) conditions, resulting in reduced arsenic content in scallops fed with these selected diatoms.

Summary: The Meric-Ergene River Basin in Turkey, an intensive agricultural region, has various water bodies contaminated with toxic metals. The levels of seven TMs in surface water samples taken from 25 different stagnant water bodies were measured and compared with water quality guidelines, showing that As concentration in lakes was significantly higher. Factors such as seasonal variations and health risks were assessed, indicating that only the lakes in the dry season had As concentrations above drinking water standards, posing potential health risks to residents. The study highlighted the need for regular monitoring of TM levels in all water bodies to ensure surface water quality.

Summary: This study assessed the water quality of four important tributaries of the Tigris River in the Bismil Plain, Turkey. Most parameters in the water samples were below drinking water limits, except for Kuru ay Stream which had higher levels of certain contaminants due to sewage and agricultural runoff. The water type in all streams was dominated by Ca-HCO3, and rock weathering was found to be the major factor affecting stream hydrochemistry. Overall, the water quality was good for drinking and irrigation purposes, except for one station in Kuru ay Stream which had poor quality water. The findings also showed that the water quality of Kurucay Stream was worse due to receiving large amounts of irrigation return flows compared to other streams.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
