CSS scientists supporting the Environmental Protection Agency’s Office of Pesticide Programs are reviewing modeling data that evaluates the potential for transfer of chemical residues from pregnant and nursing  animals to fetuses and infants. The vast majority of data come from pharmaceuticals, but staff are reviewing some data from pesticides and other environmental contaminants as well. Staff are reviewing the data for measured concentrations in maternal blood and milk as well as fetal tissues in laboratory animals and humans. The objective of this work is to better understand the various models being developed and use this modeling data to help refine risk assessment for pesticides.
