Are BKME effects on fish caused by chlorinated compounds?
- National Water Research Institute, Ontario (Canada); and others
Much of the debate about the use and environmental impacts of chlorinated compounds has been fueled by attempts to regulate the effluents discharged by pulp and paper mills. Swedish field studies have associated effects on fish health and reproduction with the discharge of AOX. A recent study has demonstrated that the effect of black liquor is three orders of magnitude more potent than the first chlorine dioxide bleachery effluent on fish. Black liquors from various pulp mills, including a mill which uses alcohol to extract lignin, also suggest that effects on fish could be caused by non-chlorinated wood extractives, Chemical analysis of isolated fractions from final BKME effluent and pure compound bioassays also indicate the high probability that non-chlorinated compounds may be responsible for fish effects. While chlorination may increase the potency of these compounds, it is clear that chlorine is not essential for effects on fish.
