What are organochlorine pesticides?

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.

Is DDT organochlorine insecticide?

In the United States (US), the organochlorine insecticide dichlorodiphenyltrichloroethane (DDT) was first used during World War II to combat malaria, typhus, and other diseases among military populations. Furthermore, organochlorine chemicals are stored in adipose tissue, including the breast.

Are all organochlorine pesticides banned?

Organochlorine pesticides (OCs) include the persistent organic pollutants (POPs) – DDT, dieldrin, aldrin, endrin, heptachlor, chlordane and mirex. These pesticides are banned in Australia, yet their residues are still found in soil and sediment.

Which is an organochlorine compound?

An organochlorine compound is a compound containing at least one carbon-chlorine bond. An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine.

What is the most common organochlorine?

Therefore, common organochlorine insecticides, including aldrin, chlordane, dichloro-diphenyl-trichloroethane, dieldrin, endrin, heptachlor, lindane, and toxaphene, are designated as persistent organic pollutants and even endocrine disrupting chemicals.

Which organochlorines are still used?

No organochlorine pesticides are currently registered for use in the home environment in Australia. The use of many organochlorine pesticides is now banned in many countries….These are a few of the most commonly found organochlorine compounds:

  • Aldrin.
  • Dieldrin.
  • Chlordane.
  • DDT (Dichlorodiphenyltrichloroethane)
  • Heptachlor.

Are organochlorines unreactive?

Use of organochlorine compounds as insecticides Their structure makes them chemically unreactive, so they are stable in soils and in the fatty tissues of animals.

Does bleach release organochlorine?

Studies have shown that toxic chlorinated gases are produced in the headspace of washing machines when hypochlorite-containing bleach is used. Laundry bleaching has also been implicated in contributing dissolved organochlorine to municipal wastewater. Organochlorine formation increases at higher wash temperature.
