Polyaromatic hydrocarbons are usually associated with soot particles, as adsorbates on the surace. Compute the relative and actual surface areas actual values in m2 g-1 of soot particles p= 0.6 g mL-1 having diameters 20 microliters and 2 microliters, respectively presuming that the prrticles are speres. Speculate on the health implications with regard to human intake of PAH compounds.
