Vital Interest

The Northern Front Range Air Quality Study concluded that for the Denver metropolitan area during 1996 and 1997, 55% of particles with an aerodynamic diameter 50% cutpoint of 2.5 μm (PM2.5) were attributable to motor vehicle exhaust particulates. The health effects of PM2.5 are currently unknown, but are under investigation. It is of vital interest to understand the chemistry, morphology, size distribution and microstructure of motor vehicle exhaust. The techniques of transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS) appear to be well suited for the analysis of the microstructure, morphology and microchemical composition of particulate matter. Previous electron microscopy observations of particulate matter from a variety of sources have found that the chemical composition and crystal structure are characteristics of the source of the particles.As part of an ongoing research project into the health effects of motor vehicle particulate matter, Southwest Research Institute (SWRI) is performing chassis dynamometer tests of a variety of vehicles and collecting samples from the exhaust stream for analysis.

Pm2.5 And Pm10

With the speed-up of urbanization, the number of motor vehicles has increased rapidly, which is the main urban air pollutant source because of too much emitted exhaust gas. Based on the motor vehicle exhaust emissions in Shandong Province in 2006, using trend extrapolation and scenario analysis, predict the motor vehicle exhaust emissions for future planning. The results show that the motor vehicles in 2015and 2020 are 27.52 million and 34.53 million, which is 1.9times and 2.38 times of the motor vehicles in 2006, respectively. For the specific air pollutants from motor vehicles exhaust in 2020, SO2, NOx, PM2.5 and PM10 will reach 28.4 thousand tons, 356.7 thousand tons, 10.8 thousand tons and 12.2 thousand tons, which will be 3 times, 1.2 times, 5 times and 5 times of the emissions in 2006. The urban air pollutions caused by motor vehicles exhaust will be very serious.
