Abstract
Dithiocarbamate pesticides form an important class of organic fungicides used all over the world to control many diseases in a variety of crops. They are of low acute toxicity, but some of these compounds, namely the ethylenebisdithiocarbamates (EBDCs) (maneb, zineb, mancozeb, metiram, and nabam), can decompose to give ethylenethiourea (imidazolidine-2-thione, ETU) (Fig. 1).
