The dioxin and furan families of chemicals are among the most studied chemicals to which humans are routinely exposed. Virtually every person in the planet has measurable concentrations of both chemical families in their blood. Dioxins mostly exist as by-products of industrial processes, such as bleaching paper pulp, waste incineration, metal smelting and refining, and in certain manufacturing processes. However, the primary source of dioxins and furans has been as combustion byproducts from all sources, including wildfires, volcanos, incinerators, smelting plants and chemical processors.
Our staff has extensive experience studying the health effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and the 156 related chemicals in the environment and in occupationally exposed workers. Our work with respect to determining acceptable concentrations in soil has been cited worldwide for almost 30 years.
