FIELD COLLECTION METHODS USED IN THE EPA NATIONAL EXPOSURE RESEARCH LABORATORY HUMAN EXPOSURE MEASUREMENT PROGRAM TO EVALUATE CHILDREN'S AGGREGATE EXPOSURE TO PESTICIDES: A TUTORIAL
TULVE, N. S. FIELD COLLECTION METHODS USED IN THE EPA NATIONAL EXPOSURE RESEARCH LABORATORY HUMAN EXPOSURE MEASUREMENT PROGRAM TO EVALUATE CHILDREN'S AGGREGATE EXPOSURE TO PESTICIDES: A TUTORIAL. Presented at OPP Health Effects Division (HED) Risk Assessment Training Program, Washington, DC, March 22, 2007.
The overall goal of this research program is to identify those chemicals, pathways, and activities that represent the highest potential exposures to children and to determine the factors that influence these exposures. The following objectives will address this goal: (1) Revise and refine the existing research plan for children's exposure measurements research. (2) Collect measurement data on children's exposures. (3) Provide analytical support to children's pesticide exposure research. (4) Develop analytical methods for pesticides in duplicate diet food samples. (5) Develop and apply analytical methods for other chemicals including but not limited to brominated diphenyl ethers, phthalates, perfluorinated chemicals. (6) Evaluate the impact of chiral chemistry on the risk to children and exposure assessment. (7) Provide support to the National Children's Study. (8) Perform data analyses to fill critical data gaps. (9) Conduct analyses of dietary samples and refine the dietary model for the dietary exposure algorithm.
A tutorial on the field sampling equipment used to collect multimedia samples.
We conduct observational human exposure measurement studies in order to understand what chemicals people come into contact with, at what levels, what the sources of those chemicals are, and where, when, how often, and why people come into contact with those chemicals in their everyday environments.
A discussion of the other types of ancillary data collected, the algorithms, and example data will be shown.
