The study took place outside an IdleAire office located in a Petro truck stop parking lot. The Petro truck stop is located in El Paso, Texas along the Interstate Highway 10 corridor. Mass concentrations of PM2.5 and PM10 along with particle number concentrations of over 190 particle size ranges were measured. The number concentration and mass concentration of particles from 0.3 mum to 20 mum were measured by the Aerodynamic Particle Sizer spectrometer (APS), Model 3321 of TSI. Number concentrations of diameters from 5.94 nm to 225 nm were measured by the Scanning Mobility Particle Sizer (SMPS), TSI (SMPS) Model 3936, with a 0.70 mum impactor that discards the larger particles. The mass concentrations of PM2.5 and PM 10 were measured by two Tapered Element Oscillating Microbalances (TEOM series 1400a, Rupprecht a Patashnick Co. Inc.). All instruments were collocated outside the IdleAire office and placed in a designated shelter to protect the instruments from excessive heat and moisture.24 Figure 3.5 APS and SMPS Wooden Cabinet. ... 32 Figure 3.11 Schematic Flow Diagram of the APS Model 3321 (TSI, 2004). ... 34 Figure 3.13 Schematic Flow Diagram of TEOM series 1400a (Rupprecht, 2007) .......... 35 Figure 3.14anbsp;...
