Temperature-dependent effects of PFOS on risk recognition and fast-start performance in juvenile Spinibarbus sinensis

Perfluorooctane sulfonate (PFOS) is a synthetic chemical substance that has become a ubiquitous environmental contaminant. It has been used in both industrial and consumer applications for over 50 yr, resulting in high levels of contamination worldwide. The potential ecotoxicity of PFOS has recently...
