RELATIONSHIPS BETWEEN QUESTIONNAIRE RESPONSES AND CHILDREN'S PESTICIDE EXPOSURE MEASUREMENTS
THOMPSON, C. B., L. S. HARRISON, R. FENSKE, G. L. ROBERTSON, AND S. C. HERN. RELATIONSHIPS BETWEEN QUESTIONNAIRE RESPONSES AND CHILDREN'S PESTICIDE EXPOSURE MEASUREMENTS. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-05/092 (NTIS PB2006-102459), 2005.
The objective of this task is to identify, develop, and evaluate simple, cost effective monitoring methods that can be used to develop exposure classifications for the proposed Longitudinal Cohort Study. Methods once evaluated should be applicable to other epidemiological studies. This project will be conducted as four concurrent subprojects.
(1) demonstrating field performance and developing uptake rates of a semipermeable membrane devise (SMPD) to collect long-term integrated samples for semivolatile organics in air,
(2) developing simple rapid methods for analyzing the SMPDs,
(3) developing rapid field or near field methods for analyzing chemical metabolites in urine,
(4) review literature to identify available but not currently used techniques for long-term integrated exposure measurements.
The objective of this project is to identify questions that indicate a higher likelihood of predicting a child's level of exposure to pesticides as input to future study designs.
