hep·ta·chlor

(hep'tă-klōr),
A chlorinated hydrocarbon insecticide for control of cotton boll weevil. It is a poison that may enter the body via skin contamination, inhalation, or ingestion. Because of human toxicity concerns, this chemical has only limited application.

In conclusion, the results from this prospective cohort study suggest that the use of certain organophosphate insecticides, including terbufos, chlorpyrifos, and fonofos, and possibly coumaphos and the organochlorine heptachlor, may be associated with elevated risk of breast cancer.
Now, we have something called fipronil that is as deadly to termites as chlordane and heptachlor but not as risky to humans.
The following OCs were detected: Dieldrin ((1aR,2R,2aS,3S,6R,6aR,7S,7aS)-3,4,5,6, 9,9-hexachloro-la,2,2a,3,6,6a,7,7a-octahydro-2,7:3, 6-dimethanonaphtho[2,3-b)]oxirene), DDT (dichlorodphenyltrichloroethane 1,1,1-trichloro-2,2-di(4-chlorophenyl)ethane), DDE (Dichlorodiphenyl-dichloroethylene (2,2-bis-(4-chlorophenyl)-1,1-dichloroethene)), DDD (Dichlorodiphenyl-dichloroethane 1-chloro-4-[2,2-dichloro-1-(4-chlorophenyl)ethyl]benzene), heptachlor epoxide (Epoxyheptachlor 1,4,5,6,7,8,8-Heptachloro-2,3-epoxy-3a,4,7,7a-tetrahydro-4,7-methanoindan), endosulfan (6,7,8,9,10,10-Hexachlorol,5,5a,6,9,9a-hexahydrc>-6,9-methano-2,4,3-benzodioxathiepine-3-oxide) and alpha-chlordane ([alpha]-Octachloro-4,7-methanohydroindane).
But these studies also suggested that most of the lindane, heptachlor, and many of the chlordanes detected in the air samples came from sources more than 60 miles away.
The herbicide list included aldrin, cis-chlordane, trans-chlordane, oxychlordane, p,p'-DDD (4,4'-DDD), p,p'-DDE, (4,4'-DDE), o,p'-DDT (2,4'-DDT), p,p'-DDT (4,4'-DDT), dieldrin, endrin, heptachlor, heptachlor epoxide isomer B, hexachlorobenzene, hexachlorocyclo-hexane (BHC) [alpha]-isomer, hexachlorocyclohexane (BHC) [beta]-isomer, hexachlorocyclohexane (BHC) [gamma]-isomer (lindane), hexachlorocyclohexane (BHC) [sigma]-isomer, methyl pentachlorophenyl sulphide (MPCPS), pentachloroani-line and pentachloronitrobenzene (quintozene).
Organochlorine pesticides, such as DDTs and its metabolites (2,4' and 4,4'-DDT, DDD and DDE), hexachlorobenzene (HCB), cyclodienes (aldrin, dieldrin, and endrin), chlordanes (heptachlor, heptachlor epoxide, cis-chlordane, transchlordane, cis-nonachlor, trans-nonachlor, and oxychlordane), HCHs ([alpha],[beta],[gamma],[delta]-isomers), mirex, and industrial chemicals like PCBs, are ubiquitous environmental pollutants (Kannan et al.

Isakov, said heptachlor has been found in Chinese fruits in Kazakhstan.
Concentrations of selenium, metals (Hg, Cd, and Pb), 20 organochlorine pesticides (HCB, [alpha]-HCH, [gamma]-HCH, aldrin, dieldrin, methoxychlor, mirex, [alpha]- and [beta]-endosulfan, heptachlor, heptachlor epoxide, [gamma]-CHL, cis-CHL, trans-nonachlor, and o,p'- and p,p'-DDD, DDE, DDT), and 24 PCB congeners were within the ranges reported for caribou in Canada.
The organochlorine pesticides assessed were: [alpha]-HCH, [beta]-HCH, [gamma]-HCH, [delta]-HCH (alicyclics), p,p'-DDT, p,p'-DDE, p,p'DDD (aromatics), Heptachlor, Heptachlor epoxide, Aldrin, Dieldrin, Endrin, Endrin aldehyde, Endosulfan I, Endosulfan II and Endosulfan sulphate (cyclodienes).
There are studies on older organochlorine pesticides like DDT, chlordane, and heptachlor, which are stored in body fat.
