The formation of nitroarenes during high-volume sampling conditions has been evaluated. Perdeuteriated fluoranthene, pyrene, benzo(a)pyrene, and perylene were coated onto filters loaded with previously collected particles and exposed to ambient gases during additional high-volume sampling. Deuteriated nitro products were formed form pyrene, benzo(a)pyrene, and perylene during 7-10-h exposure/sampling periods in Torrance, CA, during a wintertime high-NO{sub x} episode. No formation of nitrofluoranthenes was observed, and it is calculated than < 3% of the 1-nitropyrene collected during such a pollution episode was formed during collection. It is concluded that the formation of nitroarenes during high-volume sampling does not make a significant contribution to the nitrofluoranthenes and nitropyrenes observed in ambient particulate organic matter.
