Due to the characteristics of small volume and large specific surface area, the micro plastic and the micro fiber have strong pollutant adsorption capacity. The micro-plastics and the micro-fibers are similar to the riding of marine pollutants, and are very easy to be ingested by marine organisms in the process of wandering in the sea after the micro-plastics, the micro-fibers and the marine pollutants are combined, so that the marine ecosystem can be directly harmed, and the micro-plastics and the micro-fibers can enter human bodies through ecological circulation to generate great threat to the health of human beings when the human beings stand at the top end of a food chain.

Referring to the study of the ecological impact research center of coastal cities of sydney university, one of the main sources of micro-plastics and micro-fibers in the ocean is the wastewater discharged from washing machines.
