Occurrence of some organic UV filters in wastewater, in surface waters, and in fish from Swiss Lakes.

摘要: Organic UV filters are used in personal care products such as sunscreen products, and cosmetics, beauty creams, skin lotions, lipsticks, hair sprays, dyes, shampoos, so forth. The compounds enter the aquatic environment from showering, wash-off, washing (laundering), forth via wastewater treatment plants (WWTPs) (“indirect inputs”) recreational activities swimming bathing lakes rivers (“direct inputs”). In this study, we investigated occurrence of four important organic filter (benzophenone-3, BP-3; 4-methylbenzylidene camphor, 4-MBC; ethylhexyl methoxy cinnamate, EHMC; octocrylene, OC) wastewater, water fish various Swiss lakes, using gas chromatographic/mass spectrometric analyses. All were present untreated (WWTP influent) with a maximum concentration 19 μg L-1 for EHMC. data indicate seasonal variation influent loads higher warmer season (June 2002) than colder o...
