    Product Description

    Perfluorooctanesulfonamide (PFOSA) is a perfluoroalkyl substance (PFAS).1 It induces hepatic macrophage and neutrophil accumulation and fibrosis in zebrafish larvae when administered in tank water at concentrations ranging from 0.1-100 µg/L. PFOSA has been found in municipal wastewater networks.2

    WARNING This product is not for human or veterinary use.
