Title: The role of Reference Materials in measuring emerging contaminants of concern

Abstract: Standard Reference Materials (SRMs) are homogeneous, well-characterized materials that are used to validate measurements and improve the quality of analytical data (www.nist.gov/srm). The National Institute of Standards and Technology (NIST) has a wide range of SRMs that have values assigned for clinically important analytes, legacy organic pollutants, and toxic metals. These SRMs can serve as target materials for method development and measurement for contaminants of emerging concern. These natural matrix SRMs include human serum and plasma, fish tissue, soil, house dust, and domestic sludge. These SRMs are useful to the global analytical community and can serve as materials for quality assurance measurements and method development. This presentation will highlight the ten SRMs available and discuss how environmental and exposure science can benefit from their use, especially in the area of emerging chemicals.
