NEW YORK - The exhaust emitted by trucks with diesel engines appears to worsen asthma symptoms in children, as shown in a study conducted in Pasadena, California.

Dr. Michael M. Glovsky of Huntington Memorial Hospital in Pasadena presented this finding to the 58th Annual Meeting of the American Academy of Allergy, Asthma & Immunology.

Glovsky and his colleagues discovered that there was a 1.4-fold increase in asthma exacerbations in children in the fall months of October, November and December compared with the spring months of April, May and June. Moreover, the levels of particles from diesel exhaust found in the air was 2.6-fold higher in the fall than in the spring in Pasadena's neighboring town, Burbank.
