Floodplain methylmercury biomagnification factor higher than that of the contiguous river (South River, Virginia USA).
Results were consistent with a gradual methylmercury concentration increase from contaminated floodplain soil, to arthropod prey, and finally, to avian predators.
Comparisons of microplastic pollution between mudflats and sandy beaches in Hong Kong.
This study has demonstrated that the contribution of local pollution sources such as discharge from sewage treatment plants to microplastic pollution should not be neglected.

The metal-removal processes were found out to be seasonally regulated by sulfur cycling indicated by laboratory and model results, and high concentrations of metal-organic complexes were observed, especially colloidal complexes of metal and fulvic acid (FA), demonstrating adsorption to organic matter became the primary process for metal removal.
High Mercury Concentrations Reflect Trophic Ecology of Three Deep-Water Chondrichthyans
Generally, mercury concentrations appeared to increase with increased dependence on benthic versus pelagic food sources, and with higher position in the trophic web (as indicated by differences in δ15N).
Higher and more variable methylmercury biomagnification factors for floodplain than the contiguous river (South River, Virginia USA).
Results supported previous findings that the South River floodplain food webs had higher biomagnification factors than the contiguous aquatic food web and were also more variable than those of the river.
Microplastics in invertebrates on soft shores in Hong Kong: Influence of habitat, taxa and feeding mode.
Investigation of the occurrence of MPs in invertebrates collected on 18 mudflats and sandy beaches in Hong Kong found that microplastic fibres were the most abundant type of MPs, followed by pellets.
Mercury exposure and source tracking in distinct marine-caged fish farm in southern China.
Analysis of mercury concentrations and stable mercury isotope ratios in fourteen fish species from two cage-cultured farms in Southern China demonstrated that the majority of mercury in non-carnivorous species came from pellets and in carnivorous fish came from combined diets of pellets and viscera.
Linking mercury, carbon, and nitrogen stable isotopes in Tibetan biota: Implications for using mercury stable isotopes as source tracers
This is the first mercury isotope study on high altitude lake ecosystems that demonstrated specific isotope fractionations of mercury under extreme environmental conditions.
Impacts of Typhoon Mangkhut in 2018 on the deposition of marine debris and microplastics on beaches in Hong Kong.
The role cyclone induced overwash plays on introducing plastic pollution to beach environments is demonstrated and an increase in both the intensity and frequency of cyclone in the future due to global warming, and a tremendous increase in marine plastic debris, should be spent on this understudied problem.

The greater seafood and mercury ingestion rates of studied Asian groups compared with non-Asian groups suggest the need for specific seafood consumption advice for ethnic communities in the United States.
