Particle Depletion Does Not Remediate Acute Effects of Traffic-Related Air Pollution and Allergen: A Randomized, Double-Blinded Crossover Study.

CONCLUSIONS: Co-exposure to diesel exhaust and allergen impaired lung function, which was worse after particle-depletion (which increased NO2). Thus, particulates are not necessarily the sole or main culprit responsible for all harmful effects of diesel exhaust. Policies and technologies aimed at protecting public health should be scrutinized in that regard.
