Studies of effects of metal mine discharges on benthic organisms / by T. Reynoldson, A. Mudroch, F. Rosa, J. Azcue. : En13-5/95-12E-PDF
"Different approaches have been used to asses environmental impact of metal mine discharges. Complete assessment of the impact of the metal mine discharges on aquatic ecosystems must include a biological component in addition to the evaluation of physical and chemical processes. Benthic invertebrates are very appropriate for evaluating the contamination of lake or stream sediments from mining activities. These organisms reside in the sediments or at the sediment/water interface; they do not move a great deal and are therefore spatially representative; their populations are relatively stable in time; their taxonomy is reasonably well established; and their responses to environmental changes have been studied extensively. Experiments with benthic invertebrates under controlled conditions are useful for studying effects of individual processes affecting the quality of the sediments. Results from different sediment toxicity bioassays accompanied by field observations on benthos in streams and lakes in the vicinity of active or abandoned are demonstrated"--Abstract.
