Abstract: | Studies on the formation/destruction of dioxins associated with the pulping of wood artificially impregnated with an industrial grade of pentachlorophenol lend support to an earlier observation that ambient dioxins deposition may not necessarily be a unique source of the higher chlorinated dioxins occasionally found in pulps and final effluent discharges. These dioxins, which seemingly occur in products from a wide range of pulping technologies including recycle operations, may also originate from pentachlorophenol-based fungicides. |
