The CSD aids industry, government, and academia in the areas of exposure science research, remediation and regulation, air and water quality monitoring, biospecimen science and preservation, and sustainable manufacturing by advancing measurements and tools for exposure science. These activities include the identification and quantitation of emergent contaminants and pollutants in air, soil, water, and biota; measurement science and standards for natural resource damage assessment; and assessing and providing measurements and standards for biological responses at the endocrine, metabolic and proteomic level. 

The CSD activities in atmospheric science measurements are integral to the MML program in Natural Resources Monitoring and Human Health. This program covers a wide range of subjects and approaches including the production of Standard Reference Materials® and Standard Reference Data, the development of chemical informatic tools and highly accurate optical measurements for the calibration of sensors instruments measuring gas fluxes of industrial interest, atmospheric lifetimes, and aerosols radiative forcing.  These activities provide the instruments, standards, data, and informatics tools in support of the Nation’s needs to identity and quantify the amount and reactivity of gaseous species and aerosols in Earth’s atmosphere. By advancing chemical metrology and data analysis tools, these activities provide critically needed aid to industry, government, and academia in areas such as environmental research, assessment of climate change, and policy development.
