Description: This study has taken an advanced ecotoxicological approach to assess the effects on the aquatic environment of pulp bleaching effluents (representing different types of bleaching technology) using land-based model ecosystems which mimic the sublittoral zone of the Baltic Sea. Exposure was carried out at realistic, low concentrations over a time period of 4.5 months. The effluent from the conventional or oldest bleaching technology was most toxic to invertebrates, causing secondary effects on algal production. However, when assessing the overall effects on algae, invertebrates, fish growth and fish physiology caused by the effluents from newer bleaching technologies, no correlation was observed between concentration of adsorbable organic halogen (AOX) and level of effect. Nor was there any correlation between the levels of conjugated chlorophenolics or resin acids in the bile of rainbow trout and physiological effects in the fish. This lack of relationship between concentration of chlorinated organic substances and biological responses makes it necessary to search for alternative bioactive compounds. Possible candidates might be plant sterols originating from the pulped wood.
