Air pollution leads to millions of ER visits for asthma attacks worldwide
from George Washington University via Medical Xpress
Nine to 33 million visits to the emergency room for asthma worldwide may be triggered by breathing in air polluted by ozone or fine particulate matter — pollutants that can enter the lung's deep airways, according to a recently published study. Scientists have long known that breathing in air sullied by car emissions and other pollutants could trigger asthma attacks. However, the new study is the first to quantify air pollution's impact on asthma cases around the globe.
