Abstract
A bleached kraft pulp mill discharges a vast array of
substances and special attention should be given to heavy metals
and organo-chlorinated compounds. They can persist in nature for
a long period of time, are toxic to the wildlife community in certain
concentrations, and can be incorporated into the food chain. The
aim of this work is to monitor the quality of a bleached kraft pulp
mill effluent using filter-feeding molluscs. Transplanted mussels
were collected seasonally and analyzed for copper, zinc, cadmium,
lead, manganese, iron, dioxins, furans and pentachlorophenol. All
of the concentrations in mussels were low even when the mill operated
different process types and production, and also during maintenance
shut-downs. © 2000 Elsevier Science Ltd and AEHMS. All rights
