One of the mysteries of the English language finally explained.
A chlorinated hydrocarbon used as an insecticide.
Chemical formula: C₁₀H₅Cl₇
- ‘Snyder and Mulder reported that exposure of Homarus americanus larvae to the cyclodiene pesticide heptachlor can cause a delay in molting.’
- ‘The company that manufactured and sold the pesticides chlordane and heptachlor, the Velsicol Chemical Company of Chicago, threatened to sue Houghton Mifflin.’
- ‘The mystery was not what had killed the cows - the insecticides had done that - but ‘who is safeguarding the consumer to see that no residues of dieldrin or heptachlor are appearing in the milk?’’
- ‘The sequence of events made no sense: the cows had died several months after the last application of insecticide, but heptachlor volatilized in a few weeks.’
