PAHs

Polycyclic Aromatic Hydrocarbons (PAHs) are complex organic molecules composed of carbon and hydrogen atoms arranged in multiple rings. They are primarily formed from incomplete combustion of fossil fuels, such as coal, oil, and gas, and can also be found in soot, tar, and vehicle exhausts. PAHs are highly persistent and can remain in the environment for extended periods, leading to potential long-term health and environmental impacts. PAHs have been linked to a range of adverse health effects, including cancer, respiratory and cardiovascular diseases, and developmental and reproductive disorders. PAHs are also of concern due to their potential to bioaccumulate in the food chain. As a result, regulations have been put in place to limit the levels of PAHs in various products, including food, cosmetics, and industrial emissions.
