Background
Microplastics (Microplastics) are a class of solid plastic particles produced by industrial production with a diameter of less than 5 mm. The types of micro-plastics commonly detected in the environment include Polyethylene (PE), polypropylene (PP), Polystyrene (PS), polyvinyl chloride (PVC), Polyamide (PA), and polyester (PEst). The micro plastic is easy to cause plastic particle water pollution, and influences aquatic organisms to cause environmental disasters. The plastic particles can remain in water for thousands of years without disappearing, and even of a biodegradable type, are difficult to degrade in a short time.
Even more alarming is that micro-plastics are transported through the marine food chain and eventually enter the human food chain, posing a threat to human health safety. Although exact harm of the micro plastic to human health is not confirmed at present, the possibility that micro plastic particles with micron and nanometer sizes enter the circulatory system of a human body is not excluded like PM2.5, and if the micro plastic is taken for a long time, some chemical substances can be accumulated in the human body, which is obviously not beneficial to human health. Thus, various countries have gone to law to prohibit the production and use of micro-plastics. At present, the collection of micro-plastics in seawater has become an important research direction in the field of marine waste treatment.
