aThe dose at the end point of the lowest observed effect.
|BPS||Chen et al. 2002||Daphnia magna||2 or 4 days||Juvenile||Culture||NA||NA||BPS was acutely toxic in Daphnia magna; EC50, 76 mg/L (24 hr); EC50 55 mg/L (48 hr). BPS showed estrogenic activity and did not show mutagenic activity in vitro.|
|BPS||Yamasaki et al. 2004||Rat||3 days||20 days||Injection||0, 20, 100, 500 mg/kg/day||20 mg/kg||BPS exposure was estrogenic in rats via increases in uterine weight. BPS was also found to bind the estrogen receptor.|
|BPS||Ji et al. 2013||Danio rerio||21 days||3–5 months||Water||0, 0.5, 5, 50 μg/L||0.5 μg/L||BPS exposure in zebrafish showed decreases in gonad weight with respect to body weight in males and females. No changes were observed in liver or brain weight with respect to body weight. E2 levels were increased in males and in females, T levels were decreased in males, and E2/T ratios were increased in males and females. Reproduction was impaired as evidenced by decreased egg production and hatchability, and by increased time to hatch and embryo malformation rates. Gene expression in the brain and gonads of several genes involved in the hypothalamic–pituitary–gonadal axis were altered in males and females.|
|BPS||Naderi et al. 2014||Danio rerio||75 days||4–6 months||Water||0, 0.1, 1, 10, 100 μg/L||1 μg/L||BPS exposure in zebrafish showed decreased body length and weight in males, increased female to male sex ratio, decreased gonad weight, increased liver weight, decreased T3 and T4, decreased T in males, increased E2 in males and females, and increased VTG in males and females. BPS also caused disrupted reproduction, with decreased number of eggs produced, decreased hatching rate, increased time to hatch, and decreased sperm count.|
|BPF||Chen et al. 2002||Daphnia magna||2 or 4 days||Juvenile||Culture||NA||NA||EC50, 80 mg/L (24 hr); and EC50 56 mg/L (48 hr). BPF showed estrogenic activity and did not show mutagenic activity in vitro.|
|BPF||Yamasaki et al. 2003||Rat||10 days||19 days||Gavage||0, 50, 200, 1,000 mg/kg/day||100 mg/kg||BPF co-administered with TP increased the weight of the Cowper’s gland. BPF alone and combined with TP decreased body weight.|
|BPF||Yamasaki et al. 2004||Rat||3 days||20 days||Injection||0, 100, 300, 1,000 mg/kg/day||100 mg/kg||BPF induced uterine growth in immature rats. BPF was positive for relative binding affinity (E2).|
|BPF||Higashihara et al. 2007||Rat||28 days||8 weeks||Gavage||0, 20, 100, 500 mg/kg/day||20 mg/kg||There were decreases in body weight and food consumption in males and females treated with BPF. Hematological and biochemical parameters were altered, including decreased cholesterol and glucose in males and females. BPF treatment decreased T3 and increased T4 levels. BPF increased testes, liver, thyroid, brain, and kidney weights.|
|BPF||Stroheker et al. 2003||Rat||4 days||22 days||Gavage||0, 25, 50, 100, 200 mg/kg/day||100 mg/kg||BPF was shown to increase uterine weight in rats.|
