摘要

EPA has rejected calls from other federal agencies to soften its assessment of benzo(a)pyrene (BaP), an assessment that the agency is planning to use as the index against which to measure risks posed by other polycyclic aromatic hydrocarbons (PAHs), the broad class of chemicals produced from fossil fuel combustion and other sources. According to EPA's recently released draft assessment, EPA rejected 2012 calls from the Defense Department (DOD) and NASA to ease an earlier draft version of its assessment on the risks that BaP poses to human health for cancer and other adverse health effects, criticisms that industry groups are likely to reiterate in public comments. Relevant documents are available on InsideEPA.com. See page 2 for details. (Doc ID: 2446700) The draft BaP assessment is at the center of EPA's efforts to update its Relative Potency Factor (RPF) approach for assessing risks of mixtures of PAHs, which are carcinogenic compounds stemming from a wide range of natural and industrial sources, including crude oil, asphalt and vehicle emissions.
