Early warning assays : an overview of toxicity testing with phytoplankton in the North American Great Lakes / M. Munawar, I.F. Munawar and G.G. Leppard. : En13-5/89-180E-PDF
"The use of phytoplankton as test organisms in bioassays has recently gained momentum due to their simplicity, availability, sensitivity, rapidity of analysis, and cost-effectiveness. Increasing emphasis is currently being given to field and in situ experiments using indigenous populations, particulary ultra-plankton/picoplankton (20-2 um) which play a key role in the 'microbial loop' and food chain dynamics. Impact evaluation can be determined at the structural, ultrastructural and functional level. An array of techniques is available for toxicity testing including the use of either algal cultures or natural assemblages in laboratory or in situ experiments, the selection of which depends on the objectives, precision required, and project budget of the particular study. An overview is presented of the various procedures using algae in toxicity testing with a focus on the Great Lakes and an emphasis on field techniques. The effective use and application of such sensitive technology has tremendous potential for early warning detection of ecosystem perturbations in concert with a multi-trophic battery of tests"--Management perspective.
