Analytical methodology for the determination of freely available bleached kraft mill effluent-derived organic constituents in recipient sediments
Article Abstract:
A new approach for the extraction, identification and quantification of bleached kraft mill effluents was developed based on the single Soxhlet Dean-Stark extraction method. The approach uses gas chromatography and mass spectrometry to identify and quantify chlorophenolic elements and resin acids and to determine extractable organic halides. Application of the approach to a New Zealand kraft mill resulted to detection of higher concentrations of freely available organic compounds.

Detection of estrogen- and dioxin-like activity in pulp and paper mill black liquor and effluent using in vitro recombinant receptor/reporter gene assays
Article Abstract:
Paper mill black liquor and effluent samples were analyzed using in vitro recombinant receptor/reporter gene assays to determine the presence of estrogenic, dioxin-like and antiestrogenic activities. The results conclusively showed that black liquor and paper mill effluents contain estrogen- and dioxin-like ligands. However, more research is needed to identify the particular agents responsible for the adverse health effects observed in fish exposed to paper mill effluents.

A polar high molecular mass constituent of bleached kraft mill effluent Is toxic to marine organisms
Article Abstract:
The results of a research combining chemical and biological analyses on bleached kraft mill effluent (BKME) are discussed. Marine early life stage chronic toxicity tests are coupled with the fractionation of the BKME while preliminary chemical characterization of the toxic constituent are characterized. It was found that the toxicity of BKME to early life stages of marine animals and plants is caused by the polar high molecular mass constituent.
