'Kepone', also known as 'chlordecone', is a carcinogenic^[1] insecticide related to mirex, used between 1966 and 1975 in the USA for ant and roach baits. It was produced by Allied Signal Company in Hopewell, Virginia and produced nationwide pollution controversy due to improper handling and dumping of the substance into the James River.^[2] Its use was banned in 1975.
Chemically, kepone is a chlorinated polycyclic ketone insecticide and fungicide with the chemical formula ₁₀₂₁₀. The dry powder is readily absorbed through the skin and respiratory tract. Some unprotected production workers exposed to Kepone powder suffered tremors, jerky eye movements, memory loss, headaches, slurred speech, unsteadiness, lack of coordination, lost of weight, rash, enlarged liver, decreased libido, sterility, chest pain, anrthralgia, and the increased risk of developing cancer. Kepone persisted in the environment, with a half-life of about 30 years.
In July 2005, a Richmond Magazine article chronicled the ill health effects on Allied Signal employees and described how Dan Rather and CBS's 60 Minutes brought nationwide attention to the problem.^[3]
Due to the pollution scare, many businesses and restaurants along the river suffered, and then-Governor Mills Godwin Jr. shut down the James River to fishing from Richmond to the Chesapeake Bay.
