A USC study says traffic pollution is linked to childhood asthma.
A USC study says traffic-related pollution at Los Angeles County homes located near major roads and highways is linked to at least eight percent of the estimated 300,000 cases of childhood asthma in Los Angeles County.
The USC researchers focused their study on the Los Angeles basin. It found that exposure to pollution from major thoroughfares resulted in more serious childhood asthma episodes that required visits to the emergency room or even a stay in the hospital.
Researchers concluded that new California policies to reduce auto-caused greenhouse gas emissions might do more than clean up the air. They might also reduce childhood asthma and other air pollution-related diseases – including lung cancer or some neurological disorders.
