The extraction method and analysis by SF-ICP-MS demonstrate the viability of the method for the determination of low concentration metals on filter samples. The ability to directly analyze elements without any type of correction for interferences is crucial when measuring at the low nanogram per filter level. While the data shows that infant particulate profiles vary greatly by individual, the indoor exposure has a more direct influence than the outdoor exposure, especially in the winter months. Sb, Mn, Fe, Pb, and W were all found at significantly reduced levels in the personal monitors compared to the outdoor monitoring station. Performing analysis of personal exposure filter samples will require lower level measurements for the majority of elements. Traditional analytical techniques such as x-ray fluorescence and ICP will not have adequate sensitivity to make such measurements. The rapid development of infant's lungs in the first few months of life likely makes them more susceptible to pollutants than adults. All of the metals results were below NIOSH recommended exposure levels but these limits are not separately indicated for infants. Additional data and research is needed to draw correlations between exposures and health outcomes.
