Summary: Estuaries play a crucial role in controlling the transport of mercury from rivers to coastal seas. The adsorption of Hg(II) on suspended particulate matter (SPM) is the key process affecting the behavior of mercury in estuaries. The concentration of particulate mercury (PHg) is higher than that of dissolved mercury (DHg) in estuaries, indicating the importance of SPM in controlling the fate of mercury. The distribution of Hg(II) on SPM is influenced by the adsorption capacity parameter kf and the composition and properties of SPM.

Summary: Predicting net suspended sediment fluxes in coastal regions is crucial for water quality, maritime transport, and marine industries. However, the influence of aggregation and disaggregation of suspended particulate matter on net suspended sediment flux is poorly understood. This study focuses on the Menai Strait in North Wales, a tidal strait with strong currents, and finds that the flow direction and speed affect the size of suspended particles. Strong currents tear up flocs into small pieces, which are then transported towards both ends of the strait by tides. A net flux of larger particles into the central region and a net flux of small particles out occur over a tidal cycle. These findings have implications for the formation of isolated turbidity maxima in regions with strong turbulence.

Summary: Particulate matter emitted during autopsies may act as a medium for the transmission of various viruses or bacteria, leading to infections. Thus, it is crucial to reduce the exposure to these particles in indoor working environments. In this study, particulate matter in the ambient air during autopsies was measured using an aerosol spectrometer. The particle emissions from using an ordinary oscillating saw and an adapted saw with a suction unit were compared to evaluate the effectiveness of technical adaptation in reducing particles. Additionally, the impact of wearing a face mask and variations in room background concentration were analyzed. The results showed high particle concentrations while using the ordinary saw, but the exposure could be mostly avoided by using the adapted saw or wearing a face mask. On most working days, an increase in background concentration was observed. Based on these findings, the use of a proper suction unit and face mask during autopsies is necessary, along with sufficient ventilation to prevent long-lasting high background concentrations.

Summary: This study investigated the association between ambient particulate matter (PM) pollution of different sizes (PM1, PM2.5, and PM10) and the risk of rehospitalization among stroke patients in China. The results showed that higher levels of PM pollution were associated with an increased risk of rehospitalization, and the association was stronger for annual average concentrations compared to seven-day average concentrations. The study also estimated the burden of stroke rehospitalization attributable to PM pollution, and found that it is responsible for a significant proportion of rehospitalization cases and associated costs.

Summary: The study shows that the particle pollution in Hefei can be divided into three stages: accumulation, outbreak, and dissipation. During the outbreak, the particulate matter first appears in the upper part of the boundary layer and then accumulates downward, leading to ground pollution. The increase in particulate matter with a diameter of 0.8-1.6 μm is significant during the outbreak, with smaller particles growing before larger ones. Sulfate particles play a crucial role in the outbreak and dissipation of pollution, and they are the most sensitive factor in the pollution process.

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: 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.
