Adverse Effects of the Pesticide, Aldrin

Until the early 1970s the pesticide, aldrin, was widely employed for a variety of purposes. Since then though, concern over its possible adverse effects has caused the chemical's use to be progressively restricted. These concerns include its potential for bioaccumulation in the environment, as well as its possible carcinogenicity. Past research has shown that aldrin causes an increased incidence of benign and malignant liver tumors in mice. These data have led to an examination of overly exposed humansnamely, workers in insecticide factories. The studies concluded, however, that there was no evidence of aldrin's carcinogenicity.

"Aldrin" is the common name approved by the International Standards Organization for a product containing not less than 95% of 1,2,3,4,10,10hexachloro1,4,4a,5,8,8ahexahydroexo1,4endo5,8dimethanonaphthalene (7:1). In Canada, aldrin refers to the pure compound which, in Britain, is also known as hexachlorohexahydrodimethanonaphthalene (HHDN) (7:1).

Technical aldrin is actually a complex mixture of compounds (7:1). The substance exists as a darkbrown solid (4:5). Typically, it is used in various formulations which may include emulsifiable concentrates, wettable powders, granules, dusts, and solutions in hydrocarbon liquids (6:47). See below for a diagram of aldrin's chemical structure (4:6):

A chlorinated cyclodiene pesticide, aldrin, was manufactured between 1950 and 1990 (4:3). It was first synthesized in 1946 in the laboratories of Julius Hyman & Company (4:6). Not until 1948, however, was the compound described (4:6).

Small scale aldrin production started in 1948 in the plant of J. Hyman & Company in Denver, Colorado (4:6). It was subsequently marketed as "Compound 118" under the trade mark Octalene; in 1950 production started on a commercial scale (4:6).

In 1952, all rights for the production and marketing of aldrin were acquired by the Shell Chemical Corp...
