Study says particulate matter levels in truck cabs may be too high

The same emissions seeping from your truck's stacks could also be contaminating the inside of your cab at dangerous levels, according to a new study from the Environmental Protection Agency.

The study, “Measuring Air Pollution Inside and Outside of Diesel Truck Cabs,” found that the concentration of particulates within truck cabs “may be of concern,” depending on the amount of time a truck is idled and what setting its air intake system is using.

Additionally, the research – which was conducted for the EPA by the Department of Civil and Environmental Engineering at the University of Tennessee – found that regardless of the air intake settings, minute levels of particulate matter were able to enter the cab.

The study was conducted at a truck stop in Knoxville, TN, between December 2004 and January 2005, and involved the evaluation of 1996-2003 model-year trucks.
