[0002] Chemical fiber microplastics refer to microplastics produced during the production, use, and disposal of chemical fibers. The diameter of chemical fibers is micron, submicron, and nanometer levels. They disintegrate under the influence of physical and chemical conditions and immediately form microplastics. Microplastics have enrichment properties and can enrich toxic and harmful substances in the environment. They enter the body directly or indirectly through water circulation, atmospheric circulation, or biological enrichment. When the environment changes, harmful residual substances are released. Some micron and nanometer-level microplastics can participate in the exchange of cell substances and cause harm to the human body at the cellular level. At present, fiber microplastics have become one of the main components of microplastics in the environment, and the fiber component is the highest in microplastics.
