Changes in morphometry and association between whole-body fatty acids and steroid hormone profiles in relation to bioaccumulation patterns in salmon larvae exposed to perfluorooctane sulfonic or perfluorooctane carboxylic acids

► Effects of PFOA and PFOS on early larval development and morphometry. ► Effects of PFOA and PFOS on larval cellular steroid hormone levels. ► Effects of PFOA and PFOS on larval cellular lipid homeostasis. ► Higher bioaccumulation potential for PFOS, compared with PFOA. ► Association between PFOA and PFOS mediated effects on steroid hormone levels, morphometry and bioaccumulation patterns.
