Sometimes, that means changing previous ideas. In the US, we have a system that reviews and updates toxic chemicals. In 2017, benzo[a]pyrene (BaP) was updated. BaP is a polycyclic aromatic hydrocarbon (PAH) (<a href=\"https:\/\/superfund.oregonstate.edu\/all-about-pahs\">https:\/\/superfund.oregonstate.edu\/all-about-pahs<\/a>). It is also a carcinogen. Exposure to a carcinogen may increase cancer risk.<\/p>\n<p>The review of BaP found it to be 7 times less toxic than previously thought. However, it is still a carcinogen. This change may impact Superfund sites that have PAHs as pollutants. Why? Because BaP is used as a standard of toxicity for 6 other carcinogenic PAHs. When the toxicity of BaP changes, it changes these other PAHs. This means that BaP and 6 other PAHs will be considered 7 times less carcinogenic. We developed a one-page infographic describing this change (<a href=\"https:\/\/superfund.oregonstate.edu\/sites\/superfund.oregonstate.edu\/files\/image-album\/infographics\/infographics_0.jpg\">https:\/\/superfund.oregonstate.edu\/sites\/superfund.oregonstate.edu\/files\/image-album\/infographics\/infographics_0.jpg<\/a>). The Portland Harbor Superfund site has BaP and other PAHs. Only BaP and 6 PAHs will be affected by the change in toxicity. Other PAHs will not be changed.<\/p>\n<p>Want to learn more about PAHs?
