Toxicokinetics of waterborne bisphenol a in landlocked salmon ( Salmo salar m. Sebago) eggs at various temperatures
Abstract Eye‐pigmented eggs of landlocked salmon were exposed to waterbone [ 14 C]‐labeled bisphenol A at four temperatures (2, 6, 8, and 12°C). Both in accumulation and depuration experiments, the eggs were exposed to a bisphenol A concentration of 1 μg/L for 196 h. In the depuration experiment, th...
