Nearshore vertebrate predators such as marine mammals and otters are apex predators, and as such, act both as drivers of the ecosystems in which they live and as sentinels of environmental health. As apex predators, these wild animals at the top of the food chain often bioaccumalate persistent organic pollutants (termed POPs) widespread throughout the environment. Organochlorines are a type of POP that tends to be lipophilic and hydrophobic which accumulate in the fatty tissues of marine mammals and other vertebrate predators over time. There has been growing concern about these POPs in the marine environment and within wildlife, as they can potentially cause health problems. Since the 1950s there have been 81,000 papers published on organochlorines in nearshore predators and potential negative effects to the environment, wildlife and humans. Here, we review organochlorines reported in the tissues of marine mammals and other nearshore vertebrate predators since 1995. We focus on five organochlorines that have been studied the most within nearshore vertebrate predators: 2,2-bis-(p-chlorophenyl)-1,1,1-trichloroethane or dichlorodiphenyltrichloroethane (DDT), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), toxaphene, and polychlorinated naphthalnese (PCNs).
