NPAHs in airborne particulates collected at a heavy traffic road site in Kanazawa, Japan were analyzed. Fig. 1 shows chromatograms of (A) benzene-ethanol extracts from airborne particulates and (B) 21 standard NPAHs. All NPAHs except for 10-NBA were detected in the extracts. The total atmospheric concentrations of NPAHs were 3.85 pg/m and this value was 1.7 times higher than that obtained by the previous method (2.28 pg/m ). Nine newly determined NPAHs were measured. The new NPAHs and their atmospheric concentrations (in pg/m ) were 3-NBA (0.01), 5-NAc (0.28), 4-NPh (0.09), 9-NPh (0.34), 2-NA (0.25), 9-NA (0.20), 3-NFR (0.22),... [Pg.443]
