Diurnal variability of total suspended particulate, PM 2.5, by using Sensidyne Nephelometer

This research will be viewing the air quality around the South-Western towns of New Hampshire; Keene, Rindge, and Jaffrey, by using the Sensidyne Nephelometer. It uses the light scattering techniques to determine the particle concentration. By measuring heavier traffic areas, these tests can view a diurnal variation of pollution around the area. Using this Nephelometer, the average particle concentration during the morning, afternoon and evening were observed and found a significant concentration of particles during the heavy traffic period in Jaffrey than in other areas. The results show both traffic and geography of the location impact on the concentration air particles or dust particles.
