Detected in 8 diesel fuels at concentrations ranging from 0.18 to 160 mg/L with a mean
value of 46.16 mg/L (Westerholm and Li, 1994). Schauer et al. (1999) reported 2-
methylanthracene in diesel fuel at a concentration of 6 μg/g and in a diesel-powered medium-duty
truck exhaust at an emission rate of 10.4 μg/km.
California Phase II reformulated gasoline contained naphthalene at a concentration of 5.54 g/kg.
Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic
converters were approximately 1.14 and 94.1 μg/km, respectively (Schauer et al., 2002).
