摘要

Particulate matter (PM) of 2.5 microns or less is linked to serious negative health and visibility effects, and consequently is gaining increased regulatory attention. Therefore, accurate and timely measurement of ambient PM_(2.5) is an essential task in order to evaluate, model, and plan for compliance. However, accurate and timely may be conflicting needs. Many studies have concluded that a significant difference in measurements exists between the Tapered Element Oscillating Microbalance Monitors (TEOM) and the Federal Reference Method (FRM). The difference is generally related to lower ambient temperatures (i.e., at lower temperatures, the TEOM under reports PM_(2.5) concentrations). To determine if this same relationship exists in East Tennessee, PM_(2.5) concentration and ambient temperature data were obtained from TEOM, FRM and IMPROVE sites in both an urban and a rural East Tennessee area. The urban site is a heavily developed location near downtown Knoxville, Tennessee, and the rural site is at Look Rock, located on the edge of the Great Smoky Mountains National Park overlooking the Tennessee Valley. Using TEOM and FRM data from the Knox County and TEOM and IMPROVE data from Look Rock, comparisons were made between the 24-hr TEOM and the 24-hr FRM data for PM_(2.5) concentration, and investigations into the effect of the 24-hr average ambient temperature on the ratio of TEOM/FRM. This research found no significant ambient temperature effects for these sites. In fact, the TEOM sites have strong correlations with the FRM data. Contributing factors to the difference between this study's conclusion and conclusions from other research are subjects for future study.
