Includes bibliographical references (pages 64-67). "This report discusses results from artificial stream experiments in relation to the effects of effluent stressors and nutrient enrichment on benthic algal and invertebrate communities. The report also (i) compares the results from autumn 1993 and 1994 to document between-year variability in the relationships between effluent additions, and effects on primary and secondary producers, and (ii) contrasts results from spring 1994 to those from autumn 1993 and 1994 to assess the importance of seasonal changes in moderating the nutrient-contaminant effects on benthic food web interactions"--Report summary.
