Chlordecone is a chemical compound from the group of organochlorine compounds and ketones . Technically pure chlorodecone contains around 5% water and up to 0.1% hexachlorocyclopentadiene .
properties
Chlordecone is very stable in the environment with a half-life of several years.
use
Chlordecone was used as an insecticide and as an intermediate in the manufacture of the insecticide Kelevan . It was introduced in 1958 as a ketone analog by Mirex under the name Kepone and was used in the United States as an insecticide against ants and cockroaches between 1966 and 1975 . Its use was banned in the US in 1975, and in 2009 it was included in the Stockholm Convention on Globally Banned Substances. In 1979, according to a report by the French doctor Dominique Belpomme, the use on the banana plantations in Martinique and Guadeloupe resulted in an above-average number of prostate cancer cases and malformations in newborn children.
Analytical evidence
The chemical-analytical detection in environmental samples, food and animal feed is carried out after suitable sample preparation to separate the matrix and gas chromatographic separation of minor components by high-resolution mass spectrometry techniques such as flight mass spectrometry (Time-Of-Flight mass spectrometry).
