What type of pesticides are persistent in the environment?

The US EPA has classified several organochlorine pesticides, including aldrin; dieldrin; chlordane; p,p-dichlorodiphenyltrichloroethane (DDT); mirex; and toxaphene as highly persistent bioaccumulative and toxic (PBT) chemicals. The PBT pollutants thus pose a risk to the human health and ecosystem.
