HAP

Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds characterized by the presence of multiple linked aromatic rings. They primarily form during incomplete combustion of organic matter such as coal, petroleum, and wood. PAHs are found in air, soil, water, and various petroleum-derived products. Certain polycyclic aromatic hydrocarbons (PAHs) are carcinogenic and mutagenic, raising environmental and health concerns. Human exposure sources include tobacco smoke, industrial emissions, air pollution, and food contamination. Some PAHs are linked to respiratory issues, immune disorders, and cancers. The U.S. Environmental Protection Agency (EPA) targets 16 priority PAHs due to their toxicity. Regulations aim to reduce industrial emissions, and environmental monitoring employs sophisticated methods. The persistence of PAHs presents challenges, prompting research and the promotion of safer alternatives to minimize human and environmental exposure.
