Three adult medaka were kept in a 2 l glass beaker at 25 ± 1°C for 4 days. The LC50 for 96 hr was > 1000 ppb. The measured average MBP concentration in the breeding water (nominal concentration of 100 ppb) was 49.2 ppb. The average concentration in the whole bodies of medaka after 4 days was 1.92 mg/g-wet body, and the bioconcentration factor (BCF) of MBP was calculated to be 39.0. MBP in water and acetone was decomposed very easily, with about 98% of the MBP being decomposed after several hours under sunlight. MBP was also decomposed after 48 hr of illumination under a white fluorescent lamp., Journal of Health Science v.50(6) p.576-580, 2004}, pages = {576--580}, title = {Photodecomposition and Bioconcentration of a Bisphenol A Metabolite in Medaka, Oryzias latipes}, volume = {50}, year = {2004} }
