Pesticides such as DDT and heptachlor
, which are used in agriculture, often wash off in irrigation water Their presence in water and food products has alarming implications for human health because they are known to cause cancer and also may cause low sperm counts and neurological disease.
92) Pesticides and chemicals circulated on DGDs include aldrin, DDT, dieldrin, chlordane, heptachlor
, hexachlorobenzene, and polychlorinated biphenyls (PCBs).
Organochlorine insecticides such as aldrin and heptachlor
have been used until July 1995 for control of termites under houses and buildings at the time of construction and sometimes subsequent applications were made.
The pollutants are aldrin, chlordane, DDT, dieldrin, dioxins, endrin, furans, heptachlor
, hexachlorobenzene, mirex, PCBs and toxaphene.
As a result, Americans have endured one pesticide debacle after another: EDB in the nation's grain and citrus was banned only after public outcry; heptachlor
contaminated 90% of Hawaii's milk supply; aldicarb was found illegally in 1,000,000 California watermelons; and the carcinogen Alar was permitted in apple juice, putting children at "unreasonable" risk, according to the EPA.

The standard solution was made up of the following pesticides: aldrin, alpha HCH [cyclohexane, 1,2,3,4,5,6-hexachloro-,(1[alpha], 2[alpha], 3[beta], 4[alpha], 5[beta], 6[beta])], beta HCH [cyclohexane,1,2,3,4,5,6-hexachloride,(1[alpha],2[beta],3[alpha], 4[beta],5[alpha],6[beta])],deltaHCH[cyclohexane,1,2,3,4,5,6-hexachloride, (1[alpha],2[alpha],3[alpha],4P,5[alpha],6P)], lindane or gamma HCH [cyclohexane,1,2,3,4,5,6-hexachloride,(1[alpha],2[alpha],3[beta],4[alpha], 5[alpha],6[beta])], dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin, endrin aldehyde, heptachlor

They are dioxins and related furans; polychlorinated biphenyls; and the pesticides aldrin, chlordane, DDT, dieldrin, endrin, heptachlor
, hexachlorobenzene, mirex, and toxaphene.
When their tissues were analyzed for PCBs, heptachlor
, mirex, or one of several dioxin compounds, there was a striking relationship: the higher the concentration of chemicals, the smaller the organ.
