Organochlorine pesticides (OCs) were used widely in agriculture during the first half of the twentieth century in the United States and were subsequently banned from use during the 1970s. Unfortunately, some of the OCs are still in widespread use around the world. Their persistence in the environment was not apparent until Lovelock introduced the electron-capture detector (LCD) in 1960 (1). When combined with high-resolution capillary gas chromatography and appropriate sample preparation methods, the ECD provides the analytical chemist with the most sensitive means by which to...
