Acute and subacute laboratory studies are an initial assessment of pesticide toxicity and are preliminary indicators of acute environmental hazard. A carefully designed simulated field study serves to bridge the gap between laboratory indicator studies and actual hazard assessment under field conditions. A simulated field study, therefore, enables an environmental hazard assessment to be made under semi- controlled conditions that realistically mimic conditions that can be expected with full-scale field usage. The ability of a simulated field study to predict environmental hazard is no better than the degree to which it simulates actual conditions. Important factors to consider when designing a simulated field study include the selection of a nontarget species animal model indigenous to the anticipated area of use, a test site habitat that is compatible with the animal model selected, simulation of standard agricultural practices, and the generation of replicate data on the observation parameters to insure statistically reliable interpretation.
