Polycyclic aromatic hydrocarbons (PAHs) are a class of organic chemicals that consist of two or more fused benzene rings placed in a linear, angular, or cluster arrangement. They are associated with the combustion of fossil fuels and some are considered carcinogenic or mutanogenic. Undeveloped areas may have total PAH concentrations in the soil of 5µg/kg, while urban areas may have soil concentrations that range from 600 pg/kg to 3,000 ;kg/ kg. What is the concentration of PAHs in undeveloped areas in units of ppm?
