The Minnesota Department of Health-Health Risk Assessment Unit has started a full review of benzo[a]pyrene or BaP. BaP is a chemical formed from combustion, and is one of a larger class of chemicals known as polycyclic aromatic hydrocarbons (PAHs). Sources of BaP can include industrial processes, cigarette smoke, grilled or broiled foods, wood fires, motor vehicle emission, and many other activities that involve combustion of organic material. BaP is classified as carcinogenic to humans by the U.S. Environmental Protection Agency (EPA) and the International Agency for Research on Cancer (IARC). Minnesota Department of Health previously developed water guidance for BaP in 2012 and the current review will update that guidance if deemed necessary.
