PAA

PAA, or Polycyclic Aromatic Hydrocarbons, are chemical compounds made up of multiple interconnected rings of carbon and hydrogen atoms. They are naturally formed during the incomplete burning of organic material like coal, oil, gasoline, wood, and tobacco. PAA can be found in substances like soot, charred foods, and vehicle exhaust. Some PAAs are known to be carcinogenic, meaning they have the potential to cause cancer with prolonged exposure. Monitoring and controlling PAA levels is important for environmental and public health to reduce associated risks.
