Chlordane was used as a pesticide in the United States from 1948 to 1988. Chlordane is considered to have high acute toxicity based on short-term animal tests in rats.
Animal studies have reported that chronic exposure to chlordane affects the liver, kidney, blood, thyroid, and respiratory and nervous systems. Chlordane is considered as a probable human carcinogen.
The scavenging and predatory seabird species such as great black-backed gull, glaucous gull and northern fulmar had significantly higher chlordane concentrations in the liver than the other seabird species. As for hexachlorobenzene, no regional or trend differences were found for chlordanes.
The data distribution is however not even, and is therefore not well suited for trend analyses.
