The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for Friday due to high ozone levels in their Western New York region.

The advisory is in effect from 11 a.m. to 11 p.m. and covers not just Western New York but also Long Island and the New York City Metro area. The DEC's Western New York region includes counties such as Orleans, Wyoming, and Genesee.

According to a press release from the DEC, summer heat can lead to the formation of ground-level ozone, which is a major component of photochemical smog. Sources of ground-level ozone include automobile exhaust and out-of-state emission sources.

People such as young children, those who exercise outdoor, those who are involved in vigorous outdoor work, and those with respiratory diseases such as asthma are asked to consider limiting strenuous outdoor physical activity when ozone levels are highest- generally the afternoon to early evening. Going indoor will usually reduce exposure. Individuals experiencing symptoms such as shortness of breath, chest pain, or coughing should consider consulting a doctor.
