The forest industry in British Columbia has recently been seeking alternatives to chlorophenols and chlorophenates for the protection and prservation of wood. This search stems from the recognition of the hazards posed by these pesticides. They pose a significant threat to the environment because they are acutely toxic to fish, accumulate in sediments and biota, and contain high hazard impurities such as polychlorinated dibenzo-p-dioxins and dibenzofurnas. They also have been implicated in an occupational context, for example, having been associated with the induction of soft tissue sarcomas.
The purpose of this paper is to review and evaluate the available information concerning the physical and chemical properties, chemical analysis, environmental sources and distribution, excretion, placental and milk transfer and toxicity of PQ-8 and copper-8-quinolinolate.
