National Report on Human Exposure to Environmental Chemicals

The Centers for Disease Control recently released a report assessing the United States population’s exposure to environmental chemicals using biomonitoring. Biomonitoring is the assessment of human exposure to chemicals by measuring the chemicals or their metabolites in human specimens such as blood or urine. One interesting finding is relevant to asthma initiatives: while second-hand smoke exposure has decreased throughout the population, non-Hispanic blacks are still exposed to much higher levels than non-Hispanic whites and Mexican Americans.
