Description:

Because there is a scarcity of data available to assess children's actual exposure to pesticides, it is difficult to determine whether current regulatory decisions are either protective of children's health or cost-effective. The purpose of this study is to: (a) measure 'total' exposure (i.e., all important pathways to selected pesticides for a sample of children living in central-city, suburban, and rural neighborhoods in Minnesota; (b) identify and quantify relative contributions of important pathways/sources to measured exposures; and (c) compare childrens' pesticide exposure between an inner-city urban area, a suburban neighborhood, and a rural agricultural community. To accomplish these goals, a wide diversity of information will be collected over a six-day period for each child in the study, including: questionnaire date describing the residence, the occupants, and the study participant; diary data characterizing the child's activities during the study period; dermal contact data on pesticide quantities adhering to the skin; and monitoring data on pesticide concentrations in air, water, food, house dust, outside soil, urine, and blood. Results will directly improve assessments of risks to children from pesticide exposure, thereby informing and strengthening regulatory decisions about which pesticide risks are unacceptable and what, if anything, should be done about them. Moreover, the multiplicity of approaches, methods, and techniques used to measure important exposure-related variables will provide valuable insights that can be used to design future exposure and epidemiologic studies that are both more effective and efficient.
