Abstract

Correct assessment of fine particulate carbonaceous material as a functionof particle size is, in part, dependent on the determination of semi-volatile compounds, which can be lost from particles during sampling. This studygives results obtained for the collection of fine particulate carbonaceousmaterial at three eastern U.S. sampling sites [Philadelphia, PA; Shenandoah National Park, VA; and Research Triangle Park (RTP), NC] using diffusion denuder technology. The diffusion denuder samplers allow for the determination of fine particulate organic material with no artifacts, due to the lossof semi-volatile organic particulate compounds, or collection of gas-phaseorganic compounds by the quartz filter during sampling. The results show that an average of 41, 43, and 59% of fine particulate organic material was lost as volatilized semi-volatile organic material during collection of particles on a filter at Philadelphia, RTP, and Shenandoah, respectively. The particle size distribution of carbonaceous material retained by a filter and lost from a filter during sampling was obtained for the samples collectedat Philadelphia and Shenandoah. The carbonaceous material retained by the particles during sampling was found predominantly in particles smaller than0.4 mum in aerodynamic diameter. In contrast, the semi-volatile organic material lost from the particles during sampling had a mass median diameter of similar to0.5 mum.
