The CDF family contains 135 individual compounds with varying damaging health and environmental effects; those 2,3,7,8-substitued being particularly harmful. Most CDFs are produced in very small amounts as unwanted impurities after use of chlorinated compounds. Only a few of these 135 compounds have been produced and their properties (color, smell, taste, and toxicity) studied. (L952)"}]
