Polycyclic aromatic hydrocarbons (PAHs) are a class of organic chemicals associated with the combustion of fossil fuels. Undeveloped areas may have total PAH soil concentrations of 5 µg/kg, while urban areas may have soil concentrations that range from 600 µg/kg to 3,000 µg/ kg. What is the concentration of PAHs in undeveloped areas in units of ppmm?
