Average expected and actual organics (ng) on filters. Expected organics were calculated using total PM2.5 mass applied to the filter and ambient composition data. Actual values were determined with TD–GC–MS of extracted samples. Organics analyzed were hopanes (n=10), steranes (n=4), and PAHs (n=20) – abbreviated: acenaphthylene (Acy), acenapthene (Ace), fluorene (F), phenanthrene (P), fluoranthene (Flu), pyrene (Pyr), 9-fluorenone (9Flo), dibenzothiophene (DBT), 1-methyl phenanthrene (1MP), 2-methyl phenanthrene (2MP), chrysene (Chr), benzo[b]fluoranthene (BbFl), benzo(jk)fluoranthene (BjkFl), benzo[a]anthracene (BaAnt), benzo[e]pyrene (BePyr), benzo[a]pyrene (BaPyr), indeno[1,2,3-cd]pyrene (Ipyr), dibenzo[a,h]anthracene (DBahAnt), benzo[ghi]perylene (BghiPer), and benzo(ghi)fluoranthene (BghiFl).
