Occurrence of Cosmetic Ingredients as an Anthropogenic Threat to the Seas and Oceans
Summary
Researchers detected UV filters, synthetic fragrances, and microplastics from cosmetics in treated wastewater effluent discharged into coastal waters. These cosmetic-derived pollutants persisted through standard wastewater treatment and accumulated in marine environments. The findings support calls for better wastewater treatment and product regulations to reduce cosmetic pollution.
Abstract Anthropogenic pollutants get into the environment not only with untreated sewage but can also migrate with treated municipal sewage. Examples of such contaminants are UV filters (BP-3, EHS, EHMC, OC), synthetic volatile fragrances (AHTN, HHCB), and microplastics. In the case of these pollutants, it is necessary to intensify the treatment of municipal wastewater and introduce pre-treatment or additional wastewater treatment; constant monitoring of concentrations in surface and marine waters, sediments, and tissues of aquatic organisms; assessment of transformations and interactions with other pollutants in seawater and assessment of changes in conditions unfavorable for their degradation. The seas and oceans are the dumps where these pollutants eventually get it.
