Model Ecosystem Studies of Bioconcentration and Biodegradation of Pesticides

  • Robert L. Metcalf
Part of the Environmental Science Research book series (ESRH, volume 10)


Laboratory model ecosystems of microcosms are now well-established tools for investigating the environmental toxicology of pesticides, using radiolabeled molecules under standardized laboratory conditions. Laboratory model ecosystems are potentially almost as diversified as the natural environment that is being modeled and in practice have ranged in complexity from petri dishes containing soil microflora and flasks containing aquatic organisms to very complex model streams and terrestrial chambers often highly instrumented and designed for computer analysis. All of these model ecosystems are designed and operated to study (a) chemical degradation pathways, (b) transport, fate, and accumulation in living organisms, (c) toxicological effects on various organisms, (d) biochemical, physiological, and ecological parameters of environmental toxicology.
