Because nanoplastics have smaller size, larger specific surface area and are easier to absorb harmful substances than the microplastics, they pose greater threat to the environment and human health. It is essential to elucidate the toxicological mechanism of nanoplastics on health. In this paper, the research progress of migration and transformation behavior and toxicological effects of nanoplastics in the environment are reviewed, which provides an important basis for health effectsandrisk assessment ofnanoplastics.
