Micro-plastic refers to the diameter of less than 5mm of plastic particles, the study of pollutants in the micro-plastic distribution characteristics, help to accurately assess the environmental risks of micro-plastics. Chinese Academy of Sciences, Wuhan Botanical Garden researchers studied polycyclic aromatic hydrocarbons in polyethylene and other three Micro-plastic particles on the distribution of the law that the micro-plastic is a potential source of environmental pollutants and the source.
Micro-plastics mainly come from the plastic particles that are produced directly from the small plastic particles in the environment and the degradation of large pieces of plastic waste.The plastic particles are almost ubiquitous and chemically stable in aquatic ecosystems.As a result of the large ratio Surface area, micro-plastic will enrich the water pollutants, such as heavy metals and hydrophobic organic pollutants.
The distribution law of polycyclic aromatic hydrocarbons (PAHs) on polyethylene, polystyrene and polyvinyl chloride particles was studied and compared with natural sediment particles, and the team was studied by Wang Jun, a researcher at the Wuhan Botanical Garden Pollution Ecology Group, Chinese Academy of Sciences.
The results show that the adsorption strength of four kinds of solid particles to phenanthrene is polyethylene, polystyrene, polyvinyl chloride and natural sediments in turn.It is found that, compared with natural sediments, Low, but the higher the amount of desorption. This research results recently published in the international professional journal "ecotoxicology and environmental safety" on.
