PROVIDENCE, Rhode Island — The state Department of Environmental Management has issued an air quality alert for parts of southern Rhode Island.
The agency says elevated ground level ozone concentrations are expected Sunday afternoon and evening and again on Monday because of a hot and humid air mass over the area, along with southwest winds.
Ozone is formed when those weather conditions combine with pollutants from motor vehicles, industry and other sources. It can cause throat and respiratory irritation, especially during exercise and heavy activity.
The DEM says people most affected are children, the elderly and people with underlying lung conditions. The agency says people can help reduce pollution by limiting car travel and use of small engines, lawn mowers and lighter fuels.
