A new study says when air pollution in cities decline, the number of pre-
mature deaths goes down as well. The GLRC’s Mark Brush reports:
The study tracked around 8,000 people from 1974 to 1998. In that time,
air pollution levels dropped, and researchers say the number of premature deaths
decreased over time as well.
Francine Laden is the lead author of the study published in the American
Journal of Respiratory and Critical Care Medicine. She says small air
pollution particles, such as soot, cause health complications:
“What’s happening is that these particles are very, very tiny, and they get
very deep into the lung. And when they get deep into the alveoli and the
lung, they irritate the lung and can cause respiratory disease, and they
can also get into the bloodstream and then affect factors that are
associated with cardiovascular or heart disease.”
This study supports earlier findings that reduced air pollution increases
life spans. Laden says more progress can be made in cleaning up the
nation’s air, and thereby extending the lives of more people.
