Dioxin is a highly toxic byproduct produced in the manufacture of many pesticides, and by the routine operation of all incinerators, metal smelters, and chlorine-using paper mills. In 1986, EPA concluded that dioxin was one of the two or three most powerful poisons ever studied, and accordingly, set strict limits on certain releases into water. The paper industry took the lead in pressuring EPA to formally reassess dioxin. D.C. November 15, 1991.
