5.4 Fate and Effects of Aldrin/ Dieldrin in TerrestrialEcosystems in Hot Climates

Chlorinated Insecticides: Fate in Aqueous Suspensions Containing Mosquito Larvae.

Aldrin, p,p'-DDT, dieldrin, gamma chlordane. heptachlor, heptachlor epoxide, J-hydroxychlordene, and lindane were bioassayed against larvae of Anopheles quadrimaculatus Say; the remnant amounts of insecticide and metabolites in larvae and medium were determined by electron-affinity gas chromatography. The insecticides were surprisingly nonpersistent at concentrations normally used.

Aldrin and dieldrin: a review of research on their production, environmental deposition and fate, bioaccumulation, toxicology, and epidemiology in the United States.

In the last decade four international agreements have focused on a group of chemical substances known as persistent organic pollutants (POPs). Global agreement on the reduction and eventual elimination of these substances by banning their production and trade is a long-term goal. Negotiations for these agreements have focused on the need to correlate data from scientists working on soil and wat...

2. Relevance to Public Health 2.1 Background and Environmental Exposures to Aldrin and Dieldrin in the United States

Aldrin (C12H8Cl6) and dieldrin (C12H8Cl6O) are two organochlorine insecticides that were used for agricultural and public health purposes from the early 1950s until 1989, when their manufacture in the United States was discontinued. Aldrin and dieldrin were popular pesticides for corn and cotton crops, and were used as a prophylactic and for treatment of timber against termite infestation. Cons...

Degradation of endrin, aldrin, and DDT by soil microorganisms.

Twenty microbial cultures which had been shown to degrade dieldrin were tested to determine their ability to degrade endrin, aldrin, DDT, gamma isomers of benzenehexachloride (gamma-BHC), and Baygon. All isolates were able to degrade DDT and endrin, whereas 13 degraded aldrin. However, none of them was able to degrade Baygon or gamma-BHC.
