in significant quantifies in recent years include alachlor, chlordane
, heptochlor, and metribuzin.
Such hormonally active chemicals include persistent organic pollutants (POPs) such as hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), and chlordanes
The North American Commission for Environmental Cooperation (NACEC) created under a side agreement to the North American Trade Agreement, is working for a continent-wide restriction or ban on PCBs, DDT, mercury, and chlordane
The serum was analyzed for chlordane
analytes and other pesticides, and the results were compared among groups to determine if the consumption advisories reflected the level of chlordane
analytes in their blood.
Based on shifts in the ratio of the enantiomers over time, the researchers determined that recently applied pesticide is responsible for a decreasing fraction of airborne chlordane
in the Arctic.
Other toxins violate water quality standards in scattered sections of the river, including DDT, PCBs, chlordane
, arsenic and heavy metals.
Mortality of workers employed in chlordane
and heptachlor manufacture was studied by Wang and MacMahon (5).
By the late 1940's, there were several other encouraging insecticides available: benzene hexachloride, chlordane
, toxaphene, aldrin, dieldfin, to name a few of the chlorinated hydrocarbons.
Environmental Protection Agency (EPA) was founded in 1970 and soon afterward began regulating pesticides, such as banning all uses of chlordane
The waste sites contain some of the most dangerous insecticides like the Persistent Organic Pollutants (POPs) aldrin, chlordane
, DDT, dieldrin, endrin, heptachlor and organophosphates.
They are dioxins and related furans; polychlorinated biphenyls; and the pesticides aldrin, chlordane
, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, and toxaphene.
Positive associations between exposure to chlordane
isomers and testicular germ cell tumors have been reported.
