MORGAN, J. N., C. E. BERNARD, AND L. J. MELNYK. UNDERSTANDING CHILDREN'S TOTAL DIETARY EXPOSURE TO PESTICIDES. Presented at 2005 EPA Science Forum, Washington, DC, May 16 - 18, 2005.
Impact/Purpose:
The overall objective of the MCEARD dietary exposure research program is to support NERL's human exposure measurement and exposure modeling efforts by reducing the amount of uncertainty in the dietary measurements critically needed for improved risk assessment. Specifically, the research conducted under this task provides the tools needed to analyze composite food and beverage samples for the presence of pesticides, starting with pyrethroids. The specific objectives of this task are to develop and improve analytical methods for contaminants in composite food and beverage samples collected in dietary measurements studies and to analyze small numbers of samples in support of these studies. A series of analytical methods and/or journal articles are anticipated through FY07.
Description:
Recent residential monitoring studies have demonstrated that significant portion of total exposure of infants and children to environmental contaminants can result from contamination of food in the home. Children's foods become contaminated through handling and contact with surfaces. Though a series of collaborations with industry, academia and other federal agencies, EPA is gaining better understanding of the influence of eating activities on children's total dietary exposure to pesticides.
