What are chlorinated pesticides?

Chlorinated pesticides are a small but diverse group of artificially produced chemicals characterized by a cyclic structure and a variable number of chlorine atoms. Most members of the group are resistant to environmental degradation and relatively inert toward acids, bases, oxidation, reduction, and heat.

What is organochlorine pesticides PDF?

Organochlorine (OC) pesticides are synthetic pesticides widely used all over the world. They belong to the group of chlorinated hydrocarbon derivatives, which have vast application in the chemical industry and in agriculture. These compounds are known for their high toxicity, slow degradation and bioaccumulation.

What pesticide is chlorinated organic compound?

Organochlorine pesticides are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in agriculture and mosquito control. Representative compounds in this group include DDT, methoxychlor, dieldrin, chlordane, toxaphene, mirex, kepone, lindane, and benzene hexachloride.

Is DDT chlorinated?

Included in the chlorinated hydrocarbon insecticide group are DDT (dichlorodiphenyl trichloroethane), methoxychlor, aldrin, dieldrin, chlordane, toxaphene, endrin, heptachlor, and lindane (gamma isomer of benzene hexachloride (BHC)).

Which is the first chlorinated organic insecticide?

The chlorinated hydrocarbons were developed beginning in the 1940s after the discovery (1939) of the insecticidal properties of DDT.

Is DDT an OCP?

What are OCPs? These persistent, bio-accumulative pesticides include DDT, dieldrin, heptachlor and chlordane.

Is BHC organo chlorine insecticide?

Organochlorine insecticides are classified into three subgroups: (1) dichlorodiphenylethanes (DDT, dicofol, methoxychlor, and perthane), (2) chlorinated cyclodienes (aldrin, dieldrin, endrin, chlordane, endosulfan, and heptachlor), and (3) hexachlorocyclohexanes (BHC, chlordane, lindane, mirex, and toxaphene).

What are chlorinated hydrocarbons used for?

Chlorinated hydrocarbons are widely used as solvents and raw materials for the synthesis of various useful products, such as cleaning agents, pesticides and poly vinyl chloride (PVC). These chlorinated hydrocarbons, however, cause serious environmental problems when they were released into the air or water media.

What are examples of chlorinated hydrocarbons?

The chlorinated hydrocarbons were developed beginning in the 1940s after the discovery (1939) of the insecticidal properties of DDT. Other examples of this series are BHC, lindane, Chlorobenzilate, methoxychlor, and the cyclodienes (which include aldrin, dieldrin, chlordane, heptachlor, and endrin).

How do pesticides effect human health?

Pesticides are hazardous to human health, causing reproductive and developmental effects, cancer, kidney and liver damage, endocrine disruption, etc. Exposure mainly occurs through the skin, inhalation, orally, or through the eyes.

Do pesticides contain nitrates?

When unused by plants, nitrogen may infiltrate into the Groundwater , commonly in the form of nitrate (NO3-). Pesticides are typically synthetic organic compounds used to control weeds, insects, and other organisms for a variety of agricultural and non-agricultural purposes.

What are organochlorine pesticides?

Organochlorine pesticides are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in agriculture and mosquito control. Representative compounds in this group include DDT, methoxychlor, dieldrin , chlordane , toxaphene, mirex , kepone , lindane , and benzene hexachloride.
