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.

heptachlor

(hĕp′tə-klôr′)
n.
A white or tan solid, C10H5Cl7, formerly used as a pesticide, that is highly toxic to humans and is a suspected carcinogen.

219) The POPs are aldrin, chlordane, DDT, dieldrin, dioxins, endrin, furans, heptachlor, hexachlorobenzene, mirex, polychlorinated biphenyls, and toxaphene.
Similarly, in the Preston River, DDT, aldrin, dieldrin, and heptachlor residues were detected in a number of water samples.
Endrin and heptachlor showed the highest percentage contributions.
Analytes included cis-chlordane (CC), trans-chlordane (TC), cis-nonachlor (CN), trans-nonachlor (TN), oxychlordane (OC), heptachlor (HC), heptachlor epoxide (HE), pp'-DDE, pp'-DDT, and PCB.
By summing the molar concentrations of the individual analytes within each group, we also created three summary exposure variables among structurally related or isomeric forms of OCPs: [summation]chlordane (sum of oxychlordane, heptachlor epoxide, and trans-nonachlor), [summation]DDT (sum of p,p'-DDT and p,p'-DDE), and [summation]HCH (sum of [beta]-HCH and [gamma]-HCH).
Data for males and females were pooled together, because the only significant difference in results between them was in heptachlor level, with females showing a higher level at 0-.
Maternal serum samples were analyzed for [BETA]-HCH, p,p'-DDE, p,p -DDT, dieldrin, heptachlor epoxide, HCB, trans-nonachlor, oxychlordane, and 11 PCB congeners (28, 52, 74, 105, 118, 138, 153, 170, 180, 194, and 203) at the CDC from 1997 to 1999.
At a United Nations Environment Program (UNEP) meeting in Montreal this week, representatives of 92 nations began a process to enact similar global controls on 12 of those POPs: polychlorinated biphenyls (PCBs), dioxins, furans, and the pesticides aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, and toxaphene.
Mortality of workers employed in chlordane and heptachlor manufacture was studied by Wang and MacMahon (5).
Among specific organochlorine chemicals that were evaluated in < 6 studies, including dieldrin, hexachlorobenzene (HCB), [beta]-hexachlorocyclohexane ([beta]-HCH), lindane ([gamma]-HCH), heptachlor epoxide, mirex, and oxychlordane, we found positive patterns of associations (Figure 5).
In addition, testing has verified that the unit eliminates a wide range of volatile organic compounds (VOCs) like chloroform, benzene, heptachlor, styrene, PCBs, trihalomethanes and 2,4-D.
Though releases of many substances on this list, including the toxic pesticides DDT, heptachlor, and kepone, have been banned or severely restricted in the United States, such compounds continue to pollute the environment.
