New Research Linked Air Pollution to More Than 30,000 U.S. Deaths in 2015
New research linked air pollution to more than 30,000 U.S. deaths in 2015.
It found that even when air levels are considered to be safe, death rates can increase.
While air quality has increased since 1999, researchers say the findings suggest even stricter regulations are needed.
Characteristics like age, education, poverty, and smoking rates can also impact health, those factors were considered too.
Air quality trends were tracked from 1999 to 2015.
