It07:Dichloro-Diphenyl-Trichloroethane

Introduction

Dichloro-Diphenyl-Trichloroethane (more commonly abbreviated to DDT) is a well known polychlorinated pesticide, which is unusually stable. Initially, this high stability was useful as it proved resistant to break-down by light and oxidation. However, problems arose when it was found that it was very difficult to remove the pesticide from water, soil and food crops. It is also a suspected carcinogen.
