Summary: This study investigated the spatial distribution and ecological risks of 15 organophosphate esters (OPEs) in 89 water samples from the Bohai Sea and its surrounding rivers. The results showed high levels of OPEs in Liaodong Bay. Municipal wastewater and maritime shipping were identified as the main sources of OPEs in the Bohai Sea. Ecological risk assessment indicated low ecological risks for individual OPEs, but medium ecological risks for Sigma 15OPEs in minority river samples.

Summary: This study investigates the characteristics and sources of organophosphate esters (OPEs) in Jiaozhou Bay. The results show that these compounds mainly originate from effluent discharge and vehicular and marine traffic emissions. The study also finds higher concentrations of OPEs in nearshore sites and inflowing rivers. The ecological risk assessment shows that the risk of OPEs to aquatic organisms is low.

Summary: The study revealed higher concentrations of OPEs in the wet season compared to the dry season in Dongting Lake, likely due to input from tributaries discharge and wet deposition. Lower levels of TnBP and TPHP in the wet season suggest degradation under solar irradiation. Tri(2-chloroethyl) phosphate and diphenyl phosphate were identified as main components of OPEs and Di-OPs, respectively.

Summary: Limited information is available regarding the exposure risk of organophosphate esters (OPEs) through rice consumption in China. This study collected 234 rice samples from 25 provinces or cities in China and detected 16 OPEs. Each rice sample was contaminated with at least 5 OPEs, indicating the widespread occurrence of OPEs in Chinese rice. The concentrations of sigma 16 OPEs ranged from 1.46 to 552.65 μg/kg dry weight, with an average of 64.74 μg/kg dry weight.

Summary: This study is the first to comprehensively characterize the contamination profile of organophosphate esters (OPEs) in the Yangtze River. The results showed that alkyl-OPEs and halogenated OPEs were the most frequently detected compounds, with concentrations gradually increasing from the upstream to downstream of the river. Urban sampling sites had higher concentrations of OPEs compared to rural sites, and there were seasonal differences in OPE concentrations in the river water.

Summary: The prohibition and restriction of PCBs and major BFRs have led to the widespread use of OPEs as alternative chemicals, increasing their production, usage, and discharge into the environment. This study discusses the production/usage, physicochemical properties, and sample treatment techniques of OPEs, as well as their occurrence in various environmental compartments. The toxicity, human exposure, and ecological risks of OPEs are summarized, highlighting their bioaccumulation and biomagnification potential in aquatic organisms.

The results showed that the concentrations of OPEs decreased significantly compared with those before the pandemic. The release potential of OPEs from disposable surgical masks in the area also decreased, but attention should still be paid to certain compounds due to their potential ecological risks to aquatic organisms.

Summary: This study provides the first investigation of organophosphate esters (OPEs) in rivers in the Shandong Peninsula, revealing an increasing trend of total OPE concentrations from upstream to estuary regions. Municipal effluent in the Jiaozhou Bay watershed and chemical industrial wastewater in the Laizhou Bay watershed were identified as the main sources of OPEs. Regulation of TCPP and TCEP in municipal effluent, as well as TEP in chemical industrial wastewater, is necessary to protect the waters of the Shandong Peninsula.

Summary: The study found that atrazine concentrations in marine organisms from Jiaozhou Bay were relatively low, with a trend of biotic dilution as trophic levels increased. The predicted risks to species from exposure to atrazine were low, with less than 0.02% of species expected to be affected by detrimental effects. Overall, there was no significant health risk associated with consuming seafood from JZB due to the limited daily intake and low target hazard quotient of atrazine.

Summary: The extensive use of agricultural plastic films has led to a large amount of film residues in farmlands, with phthalate acid esters (PAEs) being a common pollutant. This study conducted a comprehensive investigation of diffuse PAEs loss associated with plastic films of six main crop types in China using an integrated estimation framework and high-resolution activity data. The results showed an increase in diffuse PAEs loss and identified high PAEs loss regions in eastern China, the middle-lower Yangtze plain, and eastern Yunnan and Sichuan provinces.

Summary: This study focused on the spatiotemporal occurrence and mixture risk of household and personal care products (HPCPs) in waters from rivers to Laizhou Bay. The findings revealed that p-hydroxybenzoic acid and triclosan dominated the HPCPs in the bay. While the average HPCP concentration was slightly higher in the summer of 2018 compared to the spring of 2019, the highest concentrations were observed in the spring of 2021, attributed to increased usage of methylparaben. Further research is needed to monitor the levels and risks of HPCPs in natural waters, especially in light of the COVID-19 pandemic.

Summary: This study examined the speciation and bioaccessibility of toxic heavy metals in arid calcareous soils contaminated by nonferrous metal smelting. The results showed that the contamination of these metals was mainly concentrated in the downwind areas of smelting or mining, and a significant portion of them were present in the labile fractions. The bioaccessibility of these metals in the calcareous soil was lower compared to acidic soils. These findings provide important insights into the ecological and health risks of anthropogenic toxic heavy metals in arid calcareous soils.

Summary: The Bohai Sea, the largest semi-enclosed sea of China, serves as a significant sink for microplastics (MPs) from both terrestrial and marine sources. This study summarizes the sources and migration pathways of MPs in the Bohai Sea, as well as the abundance and characteristics of MPs in water, sediments, and organisms. The study finds that coastal anthropogenic activities and marine origins contribute to the enrichment of MPs in the Bohai Sea, with a medium ecological risk observed in the Liaodong Bay. The study recommends future research priorities to focus on field surveys, sampling standardization, and establishment of toxicity database for common polymer types of MPs in the Bohai Sea.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
