Some of these pollutants are DDT, aldrin, chlordane, dieldrin, endrin, heptachlor, hexachlorobenzene, and toxaphene. These included aldrin, dieldrin, chlordane, heptachlor, texaphene, and mirex. These include&colon; aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex and toxaphene. Endosulfan is a derivative of hexachlorocyclopentadiene, and is chemically similar to aldrin, chlordane, and heptachlor. Dioxin, PCBs and chlordane are also present. In 2009, Haydn sustained neurological damage after being exposed to the pesticide Chlordane. Acarides for the environment might be hydrocyanic acid, chlorophenothane (DDT), chlordane, permethrin, pyriproxyfen, or lindane. Chlordane is excreted slowly through feces, urine elimination, and through breast milk in nursing mothers. Huntington Harbor is also contaminated by chlordane, copper, lead, nickel, and PCBs. Mycoremediation of chlordane in soil have found that contamination levels were reduced. Beluga whales also have DDT, PCB's, Chlordane, and toxaphene in their blubber. The on-site soil contained chlordane, chromium, lead, and PCB-1242. "trans"-Nonachlor is more toxic than technical chlordane and "cis"-nonachlor is less toxic. The mixture that is composed of 147 components is called technical chlordane. Chlordane is very persistent in the environment because it does not break down easily.
