POSTER: The Combination of 3 New Sampling Techniques paired with GCMS for Determination of Up take Rates and Accurate Monitoring of SVOC Endocrine Disruptors in Indoor Air
Daniel B. Cardin and Victoria L. Noad Abstract A novel approach for the quantitative passive sampling of SVOCs in ambient and indoor air down to low part per trillion levels is presented. The new approach solves issues which have prevented quantitative passive monitoring in the past, including: 1. Obtaining accurate uptake rates for all target […]
