The phototransformation of polychlorinated dibenzo-p-dioxins (PCDDs) by photolysis of pentachlorophenol (PCP) on soil surface under irradiation of UV light in the laboratory has been investigated. Octachlorodibenzo-p-dioxin (OCDD) and heptachlorodibenzo-p-dioxin (H 7 CDD) were detected from the products of the photoreactions. The effects of soil types with different basic soil physicochemical...
An extensive investigation on the input, formation and fate of PCDD/Fs in a pulp mill using reeds as raw materials in China was carried out. The main PCDD/Fs input in the production process came from reeds, which may be contaminated by PCDD/Fs from sodium pentachlorophenate to control snailborne schistosomiasis. High levels of I-TEQ in the products were observed.
