CDC Publishes Biomonitoring Data for New Chemicals, Including Blood VOCs

In January, CDC released updated tables to provide nationally representative biomonitoring data that have become available since the agency published its Fourth National Report on Human Exposure to Environmental Chemicals (PDF) in 2009. According to CDC, the updated tables provide new data for blood metals, phthalate metabolites, and volatile organic compounds, or VOCs. New chemicals measured for the first time include mono-oxoisononyl phthalate (MONP), a metabolite of di-isononyl phthalate (DiNP); mono-2-ethyl-5-carboxypentyl terephthalate and mono-2-ethyl-5-hydroxyhexyl terephthalate, which are metabolites of di-2-ethylhexyl terephthalate (DEHTP); cyclohexane-1,2-dicarboxylic acid mono carboxyisooctyl ester (MCOCH), a metabolite of DINCH; and two blood volatile organic compounds, benzonitrile and isobutyronitrile. Updated data is now available for 162 chemicals, including blood disinfection by-products; blood mercury species (inorganic, ethyl, and methyl mercury); urinary metals in the general population and in a special sample of adult smokers and nonsmokers; and serum per- and polyfluoroalkyl substances, or PFAS.

CDC’s National Report on Human Exposure to Environmental Chemicals uses biomonitoring to provide an ongoing assessment of the U.S. population’s exposure to environmental chemicals.

The updated tables and the agency’s report are both available on the CDC website.
