And the article contained the following:
Organic UV filters are of emerging concern due to their occurrence and persistence in coastal ecosystems. Because marine bacteria are crucial in the major biogeochem. cycles, there is an urgent need to understand to what extent these microorganisms are affected by those chems. This study deciphers the impact of five common sunscreen UV filters on twenty-seven marine bacteria, combining both photobiol. and toxicity anal. on environmentally relevant species. Seven bacteria were sensitive to different organic UV filters at 1000μg L-1, including octinoxate and oxybenzone. This is the first report demonstrating inhibition of bacterial growth from 100μg L-1. None of the UV filters showed any toxicity at 1000μg L-1 on stationary phase cells, demonstrating that physiol. state was found to be a key parameter in the bacterial response to UV-filters. Indeed, non-growing bacteria were resistant to UV filters whereas growing cells exhibited UV filter dependent sensitivity. Octinoxate was the most toxic chem. at 1000μg L-1 on growing cells. Interestingly, photobiol. experiments revealed that the toxicity of octinoxate and homosalate decreased after light exposure while the other compounds were not affected. In terms of environmental risk characterization, our results revealed that the increasing use of sun blockers could have detrimental impacts on bacterioplanktonic communities in coastal areas. Our findings contribute to a better understanding of the impact of the most common UV filters on bacterial species and corroborate the importance to consider environmental parameters such as solar radiation in ecotoxicol. studies. The experimental process involved the reaction of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate(cas: 6197-30-4).Electric Literature of 6197-30-4
