Marine sediments microbes degrade a limited repertoire of organic UV filters.

ABSTRACT: Understanding the processes that organic UV filters undergo in coastal and marine environments is crucial for assessing their long-term environmental risks. One key process is degradation by microorganisms in sediments. This study aimed to determine whether coastal marine sediments harbor microorganisms capable of degrading organic UV filters. Sediment from Toulon Harbor was tested for its degradation potential with respect to 12 different organic UV filters. Sediment microcosms showed degradation activity towards benzophenone-3 (BP3), 2-ethylhexyl salicylate (ES), and homosalate (HS) after 12 days. However, no degradation was observed for butyl methoxydibenzoylmethane (BM), octocrylene (OC), diethylamino hydroxybenzoyl hexyl benzoate (DHHB), drometrizole trisiloxane (DTS), phenylene bis-d
