Article Discusses Uses of CDC’s National Report on Human Exposure to Environmental Chemicals in Risk Assessments

ToxStrategies scientists Ann Verwiel, LeeAnn Racz, Liz Mittal, and William Rish have published an article titled, “CDC’s National Report on Human Exposure to Environmental Chemicals” in SETAC Globe, the organization’s monthly newsletter. The CDC’s report provides statistical summaries of biomonitoring data collected as part of the National Health and Nutrition Examination Survey (NHANES). The authors provide examples of how various risk assessors have used the NHANES data to better understand whether their study population experiences exposures that are different from those of the U.S. general population, or to evaluate how chemical exposures have changed over time. The article indicates that the descriptive statistics now provided by CDC are readily available and sufficient to compare to exposures in a specific population, such as communities with environmental justice concerns. The national data in the CDC Report can be used as a benchmark for local community data or to assess national exposures among minorities and children, who may be more vulnerable to chemical stressors or cumulative impacts from multiple stressors.
