Dieldrin can then be directly oxidized by cytochrome oxidases, which forms 9-hydroxydieldrin. An alternative for oxidation involves the opening of the epoxied ring by epoxied hydrases, which forms the product 6,7-trans-dihydroxydihydroaldrin. Aldrin and dieldrin (a metabolite of aldrin and a marketed pesticide) are the common names of two chemically related insecticides that were widely used from the 1950s to the early 1970s. After comparing blood concentrations to number of lymph nodes and tumor size a 5-fold higher risk of death was determined, comparing the highest quartile range in the research to the lower quartile range. The second mechanism makes use of aldrin's ability to block gamma-aminobutyric acid (GABA) activity. The minimal risk level at acute oral exposure to Aldrin is 0.002 mg/kg/day. [7] Aldrin is easily transported through the air by dust particles. Stable to heat and in the presence of inorganic and organic bases. As a result, Aldrin residues are rarely found in foods and animals, and then only in small amounts. Aldrin induces neurotoxic effects by blocking the GABAA receptor-chloride channel complex.
