The different ways microplastics from the water column and sediment accumulate in fish in Haizhou Bay

Shike Gao et al.

Summary: Global microplastic pollution, especially in marine ecosystems, is a serious environmental problem. This study analyzed the transmission mechanism of microplastics in the water, sediment, and fish in the artificial reef area and adjacent waters. The results showed that microplastics were mainly fibrous, blue-colored particles, and the predominant material was PET. The study also found different pathways and factors influencing the transmission of microplastics in different fish species.

Informal landfill contributes to the pollution of microplastics in the surrounding environment

Yong Wan et al.

Summary: This study investigates the characteristics of microplastic pollution in an informal landfill in South China. The results indicate that a large amount of microplastics are present in the landfill refuse and underlying soil, with most of them being fibrous, small sized, and transparent. The microplastics detected in the landfill leachate and groundwater are even smaller and more diverse in polymer types. The study demonstrates that microplastics from informal landfills can leak out to the surrounding environment.

Summary: This study investigated the sorption processes of PFOS on PE microplastic particles and the desorption of PFOS from PE MPs under simulated digestive conditions. The results showed that smaller particles had higher PFOS concentrations sorbed onto PE and were also more easily desorbed. Prolonged exposure of PE MPs to PFOS led to higher concentrations adsorbed by PE MPs, increasing the risk of transferring relevant concentrations of PFOS during digestion.

Occurrence, distribution, and input pathways of per- and polyfluoroalkyl substances in soils near different sources in Shanghai

Qinghe Zhu et al.

Summary: This study investigated the concentrations and compositions of PFAS in soils near different potential sources in Shanghai. The results showed that the concentrations of PFAS varied among different locations, with the highest concentrations near the fire station. PFAS in soils were mainly composed of short-chain perfluoroalkyl carboxylic acids. Principal component analysis indicated different correlations between long-chain and short-chain PFAS. Strong positive correlations were found within three groups of perfluoroalkyl carboxylic acids. PFAS near the fire station were likely directly emitted from a point source, while PFAS near other sites had multiple input pathways.
