Each year the "State of the Air" provides a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot.
Denver is often considered one of the healthiest cities in the country, but not when it comes to the air we breathe.
Denver has some of the highest levels of hazardous air pollution in the country, and the problem is getting worse, a new report from the American Lung Association found.
The American Lung Association says the biggest things Colorado can do to change this is support clean air legislation and take alternative transportation to reduce cars on the roads as well as becoming more conscious of our energy consumption. Eugene-Springfield is now the 19th most polluted for short-term particle pollution.
The 2019 "State of the Air" report found ozone levels increased in most cities, largely because of rising temperatures.
In Oregon, Multnomah County earned a B grade for "high ozone days". The report adds that Tuolumne County has over 3,600 adults, and 560 children, with asthma, 2,500 residents with COPD, 22 with lung cancer, 3,800 with cardiovascular disease and 5,900 with diabetes. The area also ended up at No. 17 for "short-term particle pollution". By comparison, almost 134 million people lived in counties with unhealthy air pollution levels in 2014 to 2016, and 125 million people did so in 2013 to 2015.
Tuolumne County had just over 28 "high ozone days" a year ago where the pollution was over the healthy limit, and Calaveras County registered almost 18 days. ".Warmer weather makes ozone more likely to form".
