this citation summarizes a one-page announcement of technology available for utilization. in 1984, congress appropriated fy85 monies to the u.s. environmental protection agency (epa) to assess the level of pesticide exposure experienced by the general population nonoccupational pesticide exposure study (nopes) was designed to provide initial estimates of nonoccupational exposure levels and to address the nature of the variability in exposures. nopes was based on the total exposure assessment methodology (team) approach to exposure estimation. in a team study, probability-based survey sampling procedures are combined with questionnaire data collection and modern personal monitoring techniques to obtain statistically defensible estimates of exposure levels in the general population nopes had both methodological and analytical objectives. nopes sought to apply the team approach to a class of chemicals not previously addressed by team. therefore, the primary methodological objective of nopes was to develop monitoring instrumentation, laboratory procedures, and survey questionnaires for a team study of pesticides the overall analytical objective of nopes was to estimate the levels of nonoccupational exposure to selected household pesticides through air, drinking water, food, and dermal contact. to permit assessment of regional and seasonal variations in exposure levels, the main nopes data collection was conducted in three phases: phase i: summer 1986 in jacksonville, florida; phase ii: spring 1987 in jacksonville, florida, and springfield and chicopee, massachusetts; phase iii:
