High heat causing poor air quality in parts of western Massachusetts

Weather News

While we’re dealing with another day of high heat and humidity some parts of western Massachusetts are also experiencing poor air quality.

When we have a stretch of sunny and hot days it’s common for pollution to start to build up.    

An Air Quality Alert is in effect for eastern Hampden County until 11 p.m. Wednesday night.

This means that ground-level ozone levels may approach or exceed unhealthy standards. 

Ground level ozone forms when organic compounds and oxides of nitrogen interact in strong sunlight.  

Cars, trucks, and buses give off the majority of the pollution that creates ozone.

People who are more sensitive, like the elderly, the very young or people with respiratory problems, should refrain from strenuous outdoor activities when the air quality is poor. But not everybody is affected. 

“It doesn’t me but I know it does affect a lot of people,” said Beverly Steele of East Longmeadow.

You could definitely see the haze in the air out there Wednesday.

It’s still very hot and humid out here but at least we are looking at some relief from the heat and better air quality for the end of the week.
