Summary: This study investigated the distribution and speciation of arsenic and selenium in coal and burning byproducts in five coal-fired power plants in China. It was found that the concentrations of As and Se in fly ash and gypsum were significantly higher than in coal, indicating the need for proper disposal of coal-fired solid wastes.

Summary: The study found an inverse relationship between plasma selenium levels and RCC, while a direct relationship was observed between red blood cell cadmium levels and RCC. Low plasma selenium levels may interact with high total urinary arsenic levels or high red blood cell cadmium concentration to increase the risk of RCC. The multiplicative interaction between low eGFR and high red blood cell cadmium concentration may further increase the risk of RCC.

Summary: Selenium, mercury and arsenic are widely distributed in the environment, and their toxicity depends on their concentration and forms. Accurate monitoring of these elements is necessary. Photochemical vapor generation (PVG) is a promising method for analytical atomic spectrometry, and it has been applied to determine selenium, mercury and arsenic with various separation techniques. This review summarizes the applications of PVG-analytical atomic spectrometry in selenium, mercury and arsenic speciation analysis.

Summary: This study investigated the speciation and bioaccumulation of arsenic in Parafossarulus eximius from the heavily polluted Xiang River in China. The results showed that the arsenic concentration in shellfish is influenced by sediment arsenic levels, with a mutual transformation between As(III) and As(V) in the edible and non-edible parts. Continuous consumption of shellfish may pose a significant carcinogenic risk to consumers.

Summary: The genetic diversity of native L. caerulea populations from the western and eastern edges of the Eurasian range was evaluated. The analyses showed clustering of individuals and populations according to geographic origin. However, no phylogeographic structure was found among the populations based on sequence analysis of two chloroplast DNA regions. Eastern populations of blue honeysuckle exhibited significantly greater genetic diversity compared to the populations from the Baltic region.

Summary: Selenium is an essential micronutrient that plays an important role in the development and physiological homoeostasis of animals and humans. This review discusses the role of selenium in the environment, plants, and animal bodies and explores different sources of selenium supplementation, focusing on Se-enriched yeast. Other potential sources such as Se-enriched insects and Se-nanoparticles are also examined for their use in animal nutrition. The scientific evidence suggests that sodium selenite and Se-yeast are the main options for inorganic and organic selenium supplementation, but further research is being conducted on alternative sources with high bioavailability and reduced environmental emissions.

Summary: Arsenic poses a significant risk to human health, primarily through exposure via drinking water, food, and inhalation of air. Advanced X-ray synchrotron radiation techniques are crucial for accurate monitoring and research of arsenic in the environment. High concentrations of arsenic were found in total suspended particulates from industrial areas, while low concentrations were observed in PM2.5 aerosols, impacting the speciation of arsenic in different oxidation states.

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: An Endocrine Disrupting Chemical (EDC) is a compound that disrupts the function of the endocrine system and is found in the environment. EDCs, such as Bisphenol A and pesticides, have been shown to have negative effects on the female reproductive system. Understanding the relationship between EDCs and women's health is crucial for developing strategies to protect reproductive health and informing public policy decisions.

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.

Summary: This study investigated the bacterial degradation of naphthalene (NPT) isolated from crude oil-contaminated soil. Bacillus sp. GN 3.4, a potential bacteria for NPT biodegradation, was isolated and the optimal conditions for NPT degradation were determined. The study suggests that Bacillus sp. GN 3.4 could potentially aid in bioremediation by eliminating NPT from the soil.
