Summary: This study focused on the riverbed sediments of the Changsha-Zhuzhou-Xiangtan section of the Xiangjiang River. Various methods were used to analyze the distribution pattern and risk assessment of chemical elements in the sediments. The results showed that some elements had homogeneous distributions while others had heterogenous distributions. Risk assessment of heavy metals was conducted, and the contamination levels were found to be higher in certain areas. The origins of the chemical elements were identified, with some being attributed to anthropogenic activities and others to natural processes. The contamination of certain elements, especially Cd and Mn, should be considered in environmental protection strategies in the studied watershed.

Summary: The spatial distribution, migration characteristics, and ecological risks of heavy metals in manganese contaminated sites were studied. The study found that the soil in the study area was polluted by manganese, lead, copper, cadmium, zinc, and chromium, and the concentrations of these heavy metals exceeded the limited standard. The soil samples showed significant heterogeneity within the same region. The heavy metal concentrations in the soil samples were determined using XRF and ICP-MS, and the distribution maps of heavy metals were created using the Kriging interpolation method. The pollution degree and environmental risk were assessed using Igeo, INI, and RI. The results showed that manganese was the main pollutant, followed by cadmium, lead, zinc, copper, and chromium. The spatial distribution and risk assessment of heavy metals in manganese contaminated sites provide valuable information for monitoring the migration trajectory of heavy metals and managing the ecological risk.

Summary: This study analyzed the concentrations of 11 heavy metals in surface sediments in the intertidal zones of the Yellow River Estuary, China. The results showed that these heavy metals had the same sources. Sediment particle size and total organic matter were the main factors influencing their distribution. Most sites in the study area were not contaminated with these heavy metals, except for cadmium. The risk of heavy metal pollution was higher in autumn than in summer. The findings also suggested a temporal decreasing trend in heavy metal concentrations, possibly due to reduced human activities.

Summary: This study evaluated the LD50 of different sizes of nano-sized PET (nPET) in mice and studied the health effects of single exposure to these nPETs. It was found that the toxicity and health effects were size-dependent, with smaller nPETs causing more damage. The study also found that nPET disrupted gut microbiome and metabolome, particularly lipid metabolism, and had adverse effects on weight, organ function, and mortality in mice. This is the first report on the systematic toxicity of nPET and further studies are needed to understand the long-term effects.

Summary: This study reveals that there are differences in the sources of mercury in chemosynthetic food webs and trench food webs in the deep sea. Chemosynthetic food webs mainly assimilate mercury from ambient seawater, sediments, and hydrothermal fluids formed by percolated seawater through magmatic/mantle rocks. In contrast, trench food webs mainly assimilate mercury from the monomethylmercury (MMHg) pollutants in the upper marine photosynthetic food webs. The findings suggest that mercury isotopes can be promising tools to trace the deep-sea mercury biogeochemical cycle.

Summary: This review summarizes the temporal changes in blood mercury concentrations in newborns and the general public in China from the 1980s to the 2020s. It is revealed that the blood mercury concentrations of newborns exhibited a downward trend, although not significant. The general public mercury concentrations showed a trend of initial increase followed by a decrease. Most of the cord blood and venous blood mercury concentrations in China were lower than the USEPA reference concentration of 5.8 μg/L. Continuous attention should be paid to reduce maternal and neonatal mercury exposure due to the potential effects on fetal and neonatal development.

Summary: This review summarizes the biological effects of nanoplastics (NPs) in vivo (plants and animals) and in vitro (cells). NPs can be ingested and accumulated in organisms, affecting growth, development, and reproduction at each trophic level. Factors such as surface charges, size, exposure dose, and exposure time impact the biological effects of NPs. More research is needed on the risk assessment of commonly used plastics in daily life, such as polyethylene terephthalate (PET), for better understanding of the potential harm caused by NPs.

Summary: This study investigated the impact of changes in DOM characteristics driven by end-member mixing on DOM biogeochemical reactivities. The results showed that the variations of DOM characteristics significantly affected its biogeochemical reactivities, but not all parameters and reactivities followed the conservative mixing behavior. Therefore, the effect of end-member mixing should be evaluated in the given reactivity instead of generalization.

Summary: Sulfur can effectively treat mercury pollution, but recent studies have found conflicting effects between reducing mercury mobility and promoting mercury methylation. The potential mechanism of MeHg production under different sulfur-treated species and doses is not well understood. This study investigated MeHg production in Hg-contaminated paddy soil and its accumulation in rice under elemental sulfur or sulfate treatment at different levels. The results provide insights into the mechanism of sulfur-induced MeHg production and suggest potential strategies for decreasing mercury mobility.

Summary: Recent studies have indicated that deep oceans receive mercury from various sources, but the sources of mercury in deep-sea chemosynthetic food webs are still uncertain. In this study, the researchers investigated the mercury concentrations and isotopic compositions in indigenous biota at hydrothermal fields and cold seeps. They found that hydrothermal sulfides were highly enriched in mercury, and the biota in these regions had slightly positive Delta 199Hg values. The authors suggest that deep-sea chemosynthetic food webs mainly assimilate mercury from ambient seawater/sediments and hydrothermal fluids, and the transfer of monomethylmercury from photosynthetic food webs is limited.

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.
