Some Delaware counties which were once passing the American Lung Association's daily and yearly air quality tests have been found recently to be drastically failing, according to the organization's State of the Air 2018 report.
By the metric of year-round particle pollution, Delaware falls squarely into the #12 spot for level of pollution, according to the report. According to the American Lung Association, millions of people are vulnerable to the health threats from ozone pollution. Five groups of people are especially vulnerable to the effects of breathing ozone:
• children and teens
• anyone 65 and older
• people with existing lung diseases, such as asthma and COPD
• people with cardiovascular disease
• people—even healthy adults—who work or exercise outdoors
Environmental Health Director Kevin Stewart has been an avid teacher about air quality for the last 19 years.
Stewart said there were a few standout reasons for the decline.
