Summary: The study focuses on the effect of mangrove root systems on the migration of microplastics in sediment. By analyzing the spatial distribution of microplastics in different zones and their correlation with sediment properties, it was found that the presence of mangrove root systems significantly increased the abundance of microplastics near the roots. Pore water content and pH were found to influence the abundances of different microplastic characteristics and promote their accumulation towards the root systems.

Summary: Plastic pollution has become a major global environmental issue in the past few decades, with commercial important fish species in Australian waters found to have widespread microplastic ingestion. On average, fish contained 0.94 pieces of microplastic per individual, with polyolefin being the dominant polymer group. The study reveals that microplastic contamination is prevalent across different fish species, locations, diets, and habitat niches, although the average plastic ingestion is lower compared to similar global studies.

Summary: This study investigates the characteristics of microplastic pollution in the sediments of the Xiangjiang River, China. The results show that the microplastic abundance is significantly higher in the lower reach of the river compared to the upper and middle reaches. Different types of microplastics exhibit different distribution characteristics, and hydrodynamic conditions play an important role in their distribution.

Summary: This study critically evaluates the data on microplastics in processed foods and conducts a preliminary risk assessment. The results show that the risk posed by microplastics in processed foods is limited, with lower intake in adults compared to children. A correlation is found between the pollution load of sea salts and the level of microplastic pollution in ambient seawater.

Summary: The study shows that urban rainwater pipelines play a significant role in transporting microplastics into freshwater, with the highest abundance found in the business district and the lowest in the campus area. Microplastics were mainly in fragment form, with particles smaller than 1 mm dominating, diverse in color, and primarily composed of polymers such as polyethylene, polypropylene, and polyester.

Summary: This study characterizes the abundance, chemical composition, and size of microplastics in amphipods found in the Japan Sea coastal environment. The results show that coastal amphipods may ingest large amounts of microplastics, with differences observed among different species. The study provides insights into microplastic abundance in coastal amphipods and lays the foundation for further research on microplastic ingestion by these organisms.

Summary: The abundance and characteristics of microplastics (MPs) in surface water and sediment samples from the Wanquan River estuary were investigated. The results showed high abundance of MPs in the estuary, mostly red fragments smaller than 1.0 mm, predominantly composed of antifouling paint particles (APPs). The study also found a significant positive correlation between the concentration of Cu2+ and the abundance of APPs in the sediment samples. This study expands our knowledge about MP pollution in small estuaries and highlights the ecological risk of APPs in the Wanquan River estuary to aquatic organisms.

Summary: Wastewater treatment plants are significant contributors to aquatic/terrestrial microplastic pollution. This study found that microplastics were efficiently removed from wastewater but accumulated in the sludge. The integration of advanced treatment processes and effective sludge disposal management practices are recommended to reduce microplastic release into the environment.

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 study found that the concentrations of PTEs in sediments decreased from the Yellow River Estuary to the inner Laizhou Bay due to the long-term impact of the Yellow River. Three potential sources were identified through principal component analysis: natural origins, coastal anthropogenic activities, and marine production. Among the PTEs, Cd was the most significant contaminant and was also the most sensitive factor in evaluating ecological risk.

Summary: This study investigates the long-term effects of urbanization and industrialization on coastal trace metal contamination. The results show that sediment core Q23 experiences higher trace metal contamination and ecological risks compared to core Q21. The increasing trends in metal concentrations and contamination levels are more obvious since the 2000s, and the urbanization rates in the new area are significantly correlated with historical metal concentrations in Q23.

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 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 comprehensively investigated the spatial distribution and risk assessments of REEs in upland soils of northern China. The study found a decreasing trend of REEs from northwest to northeast and common enrichment of LREEs in northern China. Ecological risk assessments indicated relatively low risks from REEs, but higher health risks for children. Continuous monitoring of REE abundance in soils is essential to prevent potential health risks.

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.
