Endrin is very toxic to fish, aquatic invertebrates, and phytoplankton (96 h LC50 for fish, aquatic invertebrates, and phytoplankton mostly below IpgH ). Eish kills were observed in areas of agricultural runoff and industrial discharge and declining populations of brown pelicans (in Louisiana, USA) and sandwich terns (in the Netherlands) have been attributed to exposure to endrin in combination with other halogenated chemicals.
