“…Our experimental system, as well as those developed by others (Hall et al, 1991(Hall et al, , 1992Haley et al, 1995;DubeH and Culp, 1996;Lehtinen et al, 1999), has been designed to reduce confounding "eld variables while maintaining a level of environmental relevance. Whether used for individual species studies, or community level impacts assessment, this mesocosm approach provides a useful tool, particularly where "eld level risk assessment is di$cult.…”

“…(3) Tumor growth may have been enhanced due to hormonal and carcinogenic effects of effluents. Wood extracts, especially plant sterols, have adverse endocrine effects including altering the reproductive biology of fishes (Lehtinen et al 1999). This may have contributed to the observed difference in the prevalence of epidermal papillomatosis between impact and reference populations since the occurrence of papillomatosis in roach is associated with high concentrations of testosterone (Kortet et al 2003a) and sex steroid injections induce papillomas in white sucker Catostomus commersoni (Premdas et al 2001).…”

We studied the association between environmental stress and epidermal papillomatosis of roach Rutilus rutilus L. in Finnish waters using a 'matched pairs' design. Populations impacted by industrial and/or sewage effluents were compared to reference populations from pristine sites. We examined both the prevalence (proportion of diseased fish) and intensity (number of scales covered by tumors) of the disease. Results of Generalized Linear Mixed Models (GLMM) indicated that the risk of papillomatosis was 7.5 times higher in males than females, and increased 1.3 times for every 10 mm increment in fish length. We controlled for the possible effects of fish size, sex and temporal variation through sampling procedures and statistical analyses. Mean prevalence of epidermal papillomatosis was 16.6 and 5.8% in impact and reference populations, respectively (10 population pairs; n fish = 1714). Results of GLMM suggested that the risk of being diseased was 2.7 times higher in the impact than reference populations. Thus, the prevalence of epidermal papillomatosis in roach can be used as an indicator of environmental stress. Results of Linear Mixed Models indicated no difference in the intensity of the disease between impact and reference populations (5 population pairs; n fish = 73; mean ± SE 10.7 ± 1.8 and 11.7 ± 2.9 scales, respectively), although prevalence was higher in impact populations in those 5 population pairs. The possible relationship between environmental stress and intensity of epidermal papillomatosis in natural roach populations remains to be demonstrated.

However, induction of papillomas can possibly also take place without viral infection (e.g. Grizzle et al. 1984, Smith et al. 1989a). Thus, the connection between papillomatosis and environmental stress can be produced both by the stress induced impairment of the immune system of fishes and by direct carcinogenic effects of contaminants (Sano et al. 1991, 1993Lee & Whitfield 1992, Baumann et al. 1996.In the North American Great Lakes, epidermal papillomatosis has been proposed as a bioindicator of contaminated waters (Munkittrick & Dixon 1989, Baumann 1992, Premdas et al. 1995, Baumann et al. 1996. The International Council for the Exploration of the Sea (ICES) has adopted epidermal papillomatosis in dab Limanda limanda as an indicator of environmental changes in the North Atlantic coastal areas (Bucke et al. 1996). Because new tools are required by the European Union's Water Framework Directive for determining the ecological status of lakes, we investigated the possible use of the roach-papillomatosis system in monitoring of environmental stress in Finnish waters.In contrast to prevalence, the intensity of ...

“…For example, plant sterols (phytosterols) may act as disrupters of the hormonal and biochemical systems of aquatic organisms (Kostamo and Kukkonen 2003). Pulp mill effluents are known to contain varying amounts of phytosterols, which have the structure similar to that of the steroid hormones of vertebrates (Lehtinen et al 1999). In addition, transformation products of sterols can have androgenic (Stahlschmidt-Allner et al 1997) and hermaphroditic effects on fish near sewage treatment plants (Zachrazewski et al 1995;Lacorte et al 2003).…”

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

On the positive side, the industry is based on the usage of renewable, photosynthetic resources. On the other hand, the industry discharges huge quantities of aqueous effluents. Large volumes (up to 70 m 3 ) of wastewater ...
