Abstract This chemical family consists of substances which are usually a mixture of several isomers or congeners, the toxic effects of which are intermixed. Experimental toxicity and human toxicity following accidental or occupational exposure are examined for: polychlorobiphenyls (PCB); polychlorodibenzodioxins, in particular 2,3,7,8-tetrachlorodibenzodioxin (TCDD) used as a defoliant in Vietnam and responsible for the Seveso incident; polybromobiphenyls; and some herbicides based on chloranilides. The extremely low thresholds of toxicity for some of these products are indicated. Particular mention is made of transformer accidents and the decontamination of areas polluted by TCDD (tetrachlorodibenzodioxin).
