Summary: This study investigates the occurrence and spatial pattern of persistent organic pollutants (POPs) in soils from the Larsemann Hills, East Antarctica. The main contaminants identified were organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). The results indicate that OCPs in soils are primarily caused by long-distance atmospheric transport, while local sources can also contribute in areas heavily impacted by human activities. Different distribution patterns were observed for PCBs and PBDEs, indicating the possibility of multiple pollution sources.

Summary: This study measured the freely dissolved OCPs and PCBs in the Indus River using polyethylene passive samplers. It found spatial variations in the distribution of these contaminants and identified agricultural fields, health sector, and industrial activities as major sources. The contaminated water intake from the river poses considerable cancer and non-cancer risks to human health.

Summary: The re-emission of persistent organic pollutants (POPs) from glaciers poses potential health risks, especially when consuming aquatic organisms from glacial waters. Understanding the varying glacier melt rates, POPs content in glaciers, and the importance of distance from emission sources are crucial in assessing and monitoring these risks. Expanding research on the synergistic toxic effects of multiple contaminants and filling spatial data gaps are recommended for future risk assessment.

Summary: This study evaluated the effects of PFAS, PCBs, OCPs, and PBDEs on oxidative stress biomarkers. The results revealed that higher levels of OCPs were associated with increased oxidative stress, involving increased pro-oxidant biomarkers such as protein oxidation, DNA damage, and lipid peroxidation, as well as decreased total antioxidant capacity. These findings contribute to a better understanding of the toxicity mechanisms of POPs.

Summary: Water scarcity not only poses economic risks but also affects the quality of national and regional development. Previous studies primarily focused on the availability of adequate freshwater supplies, overlooking the economic losses associated with inadequate water quality. However, with worsening water pollution, water scarcity caused by inadequate water quality has become more severe. This study incorporates water quality and quantity into local water scarcity risk assessments, revealing the risks and transmission pathways of virtual water scarcity in the Yellow River Basin (YRB) in China.

Summary: The study "Residue levels and spatio-temporal distribution of pesticides in different farmland-river interlaced areas of Baiyang Lake" investigated the residue levels and distribution of typical pesticides in soils and waters in different farmland-river interlaced areas of Baiyang Lake. The results showed that thiamethoxam was the dominant pesticide component with high residues in both water and soil. Although most pesticides did not pose a risk to aquatic organisms, carbendazim and propionazole should be paid attention to.

Summary: The Yellow River Basin in China, which is the largest loess deposition area in the world, has high levels of arsenic contamination in its river water and groundwater, especially in upstream and midstream. This contamination is affected by human activities and the dry climate. Corresponding measures must be implemented in these areas to address the high levels of arsenic.

Summary: Turkey's unique location allows it to receive air masses from Europe, Russia, Middle East, and Africa, making it a significant site for long-range atmospheric transport (LRT) of contaminants. Measurements in Istanbul and Izmir showed high levels of organochlorine pesticides, PCBs, and PBDEs, with DDT and HCH derivatives being dominant species. Temperature dependence indicates contributions from both LRT and local contaminated areas to elevated pollutant levels, with potential source regions identified in Africa, Middle East, Europe, and local metropolitan areas.

Summary: This study investigated the spatial distribution of five phthalate esters (PAEs) and 17 organochlorine compounds (OCs) in mussels from the Galician littoral in 2020 and its relationship with anthropogenic activities. The results showed that the Rias de Foz and Muros-Noia were the most polluted by PAEs, while the Rias de Ferrol and Barqueiro were most affected by PCBs. Additionally, the study found that the levels of most PAEs were negatively correlated with lower chlorinated PCBs and OCPs. The spatial distribution of pollutants, as confirmed by PCA, was influenced by proximity to urban wastewater for PAEs and industrial inputs for PCBs. The study's assessment of human exposure indicated that the consumption of Galician raft mussels did not pose a risk to human health.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
