“…However, the chronic toxicity of these compounds is still a concern, which requires further investigation (Kadar et al, 2010;Harris et al, 2007;Farre et al, 2008). Some UV filters such as 3-(4-methylbenzylidene) camphor (4-MBC) and octyl 4-methoxycinnamate (OMC) have exhibited adverse biological effects due to their hormonal activities (estrogenic, antiestrogenic, androgenic and antiandrogenic) as demonstrated in both in vitro and in vivo tests (Schlumpf et al, 2001;Heneweer et al, 2005;Maerkel et al, 2005;Kunz and Fent, 2006;Klammer et al, 2007). A major source of BTs and UV filters is the release of effluent and sludge from wastewater treatment plants (WWTPs).…”

“…Consequently, BP-3 reaches aquatic environments directly through recreational activities (swimming and bathing) and indirectly by way of wastewater treatment plants (WWTPs) because of incomplete removal [2,5,6]. It is reported that BP-3 showed hormonal activities (estrogenic, antiestrogenic, androgenic, and antiandrogenic) in fish in both in vitro and in vivo tests [7][8][9]. In male medaka and male California halibut BP-3 lead to vitellogenin induction [10,11].…”

Abstract-Biodegradation of the ultraviolet (UV) filter benzophenone-3 (BP-3) was investigated in the laboratory to understand its behavior and fate under oxic and anoxic (nitrate, sulfate, and Fe [III]-reducing) conditions. Biodegradation experiments were conducted in microcosms with 10% of activated sludge and digested sludge under oxic and anoxic conditions, respectively. Benzophenone-3 was well degraded by microorganisms under each redox condition. Under the redox conditions studied, the biodegradation half-life for BP-3 had the following order: oxic (10The results suggest that anaerobic biodegradation is a more favorable attenuation mechanism for BP-3. Biodegradation of BP-3 produced two products, 4-cresol and 2,4-dihydroxybenzophenone, under oxic and anoxic conditions. Biotransformation of BP-3 to 2,4-dihydroxybenzophenone by way of demethylation of the methoxy substituent (O-demethylation) occurred in cultures under each redox condition. The further biotransformation of 2,4-dihydroxybenzophenone to 4-cresol was inhibited under oxic, nitrate-reducing, and sulfate-reducing conditions. Environ. Toxicol.

“…Both the primary compound and its metabolites are excreted in urine in the form of glucuronated derivatives (Okereke et al, 1993;Kadry et al, 1995;Calafat et al, 2008). BP3 has low acute toxicity , but it shows estrogenic activity in several fish species, where it acts as vitellogenin inducer (Schlumpf et al, 2001;Schlenk et al, 2005;Kunz et al, 2006;Coronado et al, 2008). Therefore, BP3 has potential to cause feminisation of male fish.…”

AbstractThe UV filter benzophenone-3 (BP3) has UV photolysis quantum yield s −1 ), the CO 3 −• degradation process could be somewhat important for DOC < 1 mg C L −1 . The predicted half-life time of BP3 in surface waters under summertime conditions would be of some weeks, and it would increase with increasing depth and DOC. BP3 transformation intermediates were detected upon reaction with • OH. Two methylated derivatives were tentatively identified, and they were probably produced by reaction between BP3 and fragments arising from photodegradation. The other intermediates were benzoic acid (maximum concentration ∼10% of initial BP3) and benzaldehyde (1%).
