Decreases in Air Pollution Shown to Improve Children’s Health

The reduction in sulfur dioxide and total suspended particulate levels in eastern Germany following reunification provides a natural experiment to assess associated improvements in human health.

This study sought to examine the effect of the decline in air pollution due to a reduction in coal combustion on elementary school children’s symptoms of bronchitis.

Researchers conclude, “the prevalence of nonasthmatic respiratory disorders may be reduced within a short time period by improving air quality. Our data on long-term exposures to air pollution indicate the reversibility of adverse health effects in children and add further evidence of a causal association with combustion-related air pollutants.”
