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±10.69mgMP/g and average size of 313±130μm; whereas, 2.2% of shower gel products contained an average weight of 17.80±7.50mgMPs/g with an average size of 422±185μm. 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 39tons MPs were released into the environment based on PCCPs use in China based on available data.
微塑料（MPs）已成为一个全球性的主要问题；它们从各种产品中的释放会影响到水生环境，尤其是海洋生态系统。作为 MPs 的主要来源之一，含有 MPs 的个人护理和化妆品产品（PCCPs）促成了这种环境风险。我们走访了中国北京的几家连锁超市，以确定含有 MPs 的 PCCPs。总体而言，7.1%的洗面奶含有 MPs，平均重量为 25.04±10.69mgMP/g，平均尺寸为 313±130μm；而 2.2%的沐浴露产品含有平均重量为 17.80±7.50mgMPs/g，平均尺寸为 422±185μm。基于拉曼和傅里叶变换红外光谱分析，大多数 MPs 由聚乙烯制成，而只有少数由核桃壳和碳颗粒制成。最后，根据现有数据，基于中国 PCCPs 的使用情况，估计有 39 吨 MPs 被释放到环境中。
