Abstract

Sludges and treated effluents from various Ontario pulp and paper plants were analyzed for chlorinated dibenzo-p-dioxins (CDDs) and dibenzofurans (CDFs). Results show that 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-4CDD) is a product of bleached Kraft mills. The only CDD/CDF congeners found in more than one sludge sample were the tetrachlorinated CDDs (4CDD) and CDFs (4CDF) and octachlorinated CDD and CDF. Levels of 2,3,7,8-4CDD ranged from 170 to 370 ppt in the secondary treatment sludge from two bleached Kraft mills.
