Study suggests some filtering of particulates from diesel exhaust may worsen allergy-induced lung impairment due to increase in NO2

Green Car Congress

Air pollution from diesel engines may worsen allergy-induced lung impairment more when tiny particles are filtered from the exhaust than when they are not, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
