Summary

Microplastics enter the environment from two main source categories: primary sources producing small particles directly (such as microbeads in cosmetics) and secondary sources formed by fragmentation of larger plastic items. Understanding these distinct pathways is essential for targeting pollution prevention strategies at the most impactful entry points.

Generally, microplastics (MPs) in the environment come from two main types of source, which lead to different sizes of plastic particles: one is the primary source, and another is the secondary source. However, it is not easy or even impossible to identify the exact...
