Ecotoxicology is the science that seeks to predict the impacts of
chemi cals upon ecosystems. This involves describing and predicting
ecological changes ensuing from a variety of human activities that
involve release of xenobiotic and other chemicals to the
environment. A fundamental principle of ecotoxicology is embodied
in the notion of change. Ecosystems themselves are constantly
changing due to natural processes, and it is a challenge to
distinguish the effects of anthropogenic activities against this
background of fluctuations in the natural world. With the
frustratingly large, diverse, and ever-emerging sphere of envi
ronmental problems that ecotoxicology must address, the approaches
to individual problems also must vary. In part, as a consequence,
there is no established protocol for application of the science to
environmental prob lem-solving. The conceptual and methodological
bases for ecotoxicology are, how ever, in their infancy, and thus
still growing with new experiences. In deed, the only robust
generalization for research on different ecosystems and different
chemical stresses seems to be a recognition of the necessity of an
ecosystem perspective as focus for assessment. This ecosystem basis
for ecotoxicology was the major theme of a previous pUblication by
the Ecosystems Research Center at Cornell University, a special
issue of Environmental Management (Levin et al. 1984). With that
effort, we also recognized an additional necessity: there should be
a continued develop ment of methods and expanded recognition of
issues for ecotoxicology and for the associated endeavor of
environmental management."
