Pahs are polycyclic aromatic hydrocarbons which contain several fused benzene rings. They are ubiquitous in the environment and can be found in coal, crude oil, and gasoline. Pahs are also produced by burning tobacco, wood, and other organic materials.
Pahs are of concern because they are carcinogenic and mutagenic. Exposure to pahs can occur via inhalation, ingestion, or skin contact. Pah-containing products such as creosote and coal tar have been used for centuries in various industrial applications. Today, pahs are still used in some industries, such as the production of dyes, pigments, and pesticides.
There is no single “safe” level of exposure to pahs; the risk of developing cancer or other health effects depends on many factors including the duration and intensity of exposure, as well as an individual’s susceptibility. Some people may be more sensitive to the effects of pahs than others due to genetic differences or preexisting medical conditions.
If you think you have been exposed to pahs, it is important to consult a healthcare professional who can assess your individual risk and recommend appropriate treatment or monitoring measures.
