Microplastics (MPs) have become a major global issue; their release from various products affects the aquatic environment, especially marine ecosystems. As a primary source of MPs, personal care and cosmetics products (PCCPs) containing MPs contribute to this environmental risk. We visited several supermarket chains in Beijing, China to identify PCCPs containing MPs. Overall, 7.1% of facial cleansers contained MPs, with an average weight of 25.04 +/- 10.69 mg MP/g and average size of 313 +/- 130 mu m; whereas, 2.2% of shower gel products contained an average weight of 17.80 +/- 7.50 mg MPs/g with an average size of 422 +/- 185 mu m. The majority of MPs were made of polyethylene, based on Raman and Fourier transform-infrared spectra analyses, while only a few were made of walnut shells and carbon particles. Finally, estimated 39 tons MPs were released into the environment based on PCCPs use in China based on available data.
