The Purpose: This project quantifies emission rates and chemical fingerprints for source and receptor models that determine ecosystem impacts of different source types.This real world emission differs from those obtained by certification and compliance tests.

In 2009, Desert Research Institute (DRI), Reno, NV, USA, developed a sampling unit capable of taking emission samples from the mobile heavy hauler truck fleet. Field trials were conducted at Syncrude and the Muskeg River Mine in the fall 2009 with the mobile heavy hauler truck fleet. The re-suspension and analysis of fugitive dust sources was also carried out in 2009.  A draft report was submitted in 2010.

Preliminary results indicate average particle number emission factors (EFs) were different from both sites; one site is in the same range as that measured from highway tunnels restricted to on-road HD diesel trucks.  EFs for H2S and NH3 were low, for NMHC, NOx, CO, and PM2.5 were less than the US EPA Tier 1 limits. Most carbohydrates and organic acids were below detection limits. CO2 correlated to engine speed, load, and temperature, as well as to NO. CO correlated with BC and PM2.5.  Particle number and NOx had higher EFs when the engine was idling. PM2.5 was higher during the dump-to-load segment when the truck was empty and the route was generally downhill. The NMHC source profile was dominated by alkanes, cycloalkanes, and alkenes. Carbon was the most abundant species in the PM2.5. Among the 113 measured non polar organic compounds of the PM2.5 particles, alkanes were the most abundant species. Particle associated PAHs are mostly two- to four-ring. In the semi volatile PAH, hopanes and steranes were detected in appreciable amounts.

Further field work was initiated in October 2010, including additional truck monitoring. Stack monitoring was undertaken in Feb/March 2010 and will continue in winter 2011.
