Alkylated Chrysenes
Combustion usually yields the characteristic pyrogenic distribution (C0 > C1 >
C2 > C3) for chrysenes in soots of diesel, wood, coal, refined petroleum products,
etc. However, the dominance of parent over alkylated PAHs in diesel soots is unique
for chrysenes (Wang et al. 1999b ). Other LMW (2-4 ringed) PAHs volatilize and are
