Abstract:While perfluorotridecanoate acid (PFTriDA), a long-chain perfluorinated carboxylic acid, has been widely detected in environment and wildlife in recent years, there is still lack of mechanism information on the tissue distribution and bioconcentration in fish. The tissue distribution and bioconcentration in the medaka (Oryzias Latipes) exposed to different concentrations of PFTriDA was assessed. The highest concentration of PFTriDA was detected in gonad, followed by egg, liver and carcass, which was similar to the tissue distribution in wild Chinese Sturgeon (Acipenser sinensis) except for gonad. For all tissues, male accumulated higher concentrations than female, which was demonstrated to be mainly due to high maternal transfer efficiency in adult female. The bioconcentration factor (BCF) was found to be decreased with increasing the exposure concentration of PFTriDA.
