Endocrine disrupting alkylphenols and bisphenol-A in coastal waters and supermarket seafood from Singapore

, : Endocrine disrupting alkylphenols and bisphenol-A in coastal waters and supermarket seafood from Singapore. Marine Pollution Bulletin 48(11-12): 1161-1167

In this study, surface seawater samples collected from 28 coastal locations around Singapore from May to December 2000 were analysed to determine the presence of alkylphenols and bisphenol A. Seafood samples (blood cockle, Anadara granosa; white clam, Meretix meretix; squid, Loligo sp.; tiger prawn, Penaeus monodon; swimming crab, Portunus pelagicus; carangid fish, Decapterus russelli) purchased from a local supermarket chain between June 2000 and February 2001 were also examined for these compounds. The results showed that recoveries ranged between 73.9 and 96.5% for seawater samples, and between 92.0 and 111.1% for tissue samples. The following 10 alkylphenols, in addition to bisphenol A, were detected in seawater samples from the 28 locations: 4-nbutylphenol, 4-t-butylphenol, 4-n-pentylphenol, 4-n-hexylphenol, 4-n-octylphenol, 4-t-octylphenol, 4-n-heptylphenol, 4-nonylphenol, 2-4-dichlorophenol, and PCP (pentachlorophenol). The total alkylphenols and bisphenol A concentration is lower than the Environmental Protection Agency (US-EPA) maximum permissible concentration range of phenols of 60-400 micro g/litre. Alkylphenols and bisphenol A were also detected in all the seafood samples, with concentrations of up to 530.4 ng/g wet weight (w.w.) of total alkylphenols and between 13.3 and 213.1 ng/g w.w. of bisphenol A in prawn, crab, blood cockle, white clam, squid, and fish. This study indicates that alkylphenols and bisphenol A are present in seafood products commercially available to the public in Singapore.
