ABSTRACT
There is no safe level for dioxins, the environmentalists argue. Industrialists say there is, and refer to the hypothesis that elements of polychlorinated dibenzo-para-dioxins and polychlorinated dibenzofurans, commonly known as dioxins and furans, have always been in the environment. Some scientists agree that the burning of wood for heating and cooking and other naturally occuring combustion processes have generated dioxins and furans. This hypothesis has been shattered in recent years with the revelations, based on data derived from the analysis of ancient human tissue, that the source of dioxins and furans is recent and anthropogenic'!
