Parts of Maine will experience elevating ground-level ozone concentrations on Thursday, the Maine Department of Environmental Protection said.
The agency said the ozone levels are expected to reach unhealthy levels for the southwest coast and the high elevations of Acadia National Park. Elevated ozone levels can cause reduced lung function and irritation among children, healthy adults who exert themselves and people who suffer from a respiratory disease, the agency said.
The environmental department said Mainers can protect themselves from unhealthy air quality by adjusting their schedules to avoid strenuous outdoor activity during the afternoon.
