Characterization of PM10 Emission Rates from Roadways in a Metropolitan Area Using the SCAMPER Mobile Monitoring Approach

The SCAMPER mobile system for measuring PM10 emission rates from paved roads was used to characterize a wide variety of in the Phoenix, AZ metropolitan area. Week-long sampling episodes were conducted March, June, September, and December. A 180 km-long route utilized traveled total 18 times. rate measurements made at 5-s resolution over 3200 km with precision approximately 25%. varied by two orders magnitude generally low unless road impacted dust deposited activities such as construction, sand gravel operations, agriculture, vehicles traveling on or near unpaved shoulders roads. data tabulated into averages each 67 segments that divided into. segment-averaged ranged zero 2 mg m−1, an average 0.079 m−1. There no significant difference between seasons. major drop weekend, when generation construction are expected be much reduced. By Monday, had risen levels previous Friday. This indicates quickly reach equilibrium generating potential.
