Ames assay chromatograms of extracts of diesel exhaust particles from heavy-duty trucks on the road and from passenger cars on a dynamometer.


Particles from diluted exhaust of heavy-duty diesel trucks were collected on filters in the Allegheny Mountain Tunnel on the Pennsylvania Turnpike. Dichloromethane extracts of these particles were separated into 65 fractions by normal-phase high-performance liquid chromatography, and Ames assays (TA98 without activation) were carried out on each fraction… (More)
