Recently, the U.S. Centers for Disease Control and Prevention (CDC) made available an online, interactive version of biomarker data in its National Report on Human Exposure to Environmental Chemicals (CDC Report). The CDC Report presents biomonitoring data for a variety of chemicals—data that are representative of national exposures. These data have been collected as part of the National Health and Nutrition Examination Survey (NHANES) but, until now, have not been readily and publicly accessible. The CDC Report provides descriptive statistics (geometric means and percentiles with confidence intervals) from the NHANES data set for the total population and by age group, gender, race and ethnicity. Whereas more in-depth statistical and multivariate analyses can be performed with the original NHANES data, the online CDC Report webpage (Biomonitoring Data Tables for Environmental Chemicals) provides summary tables that can be used to quickly review and compare to other data. This new capability offers easy access to scientists, physicians and public health officials and provides context for local environmental chemical exposures.
