Ground-level ozone concentrations will be climbing in Maine Wednesday and are expected to reach unhealthy levels for the Southwest Coast and Mid-Coast regions according to the Maine Department of Environmental Protection (DEP). Unhealthy levels of ozone will continue into Thursday for the entire coastline. Ozone values for interior regions will likely reach the Moderate range Wednesday and possibly into Thursday.

Particle pollution levels will be Moderate statewide during this event.

At high ozone levels, children, healthy adults who exert themselves, and individuals suffering from a respiratory disease such as asthma, bronchitis or COPD can experience reduced lung function and irritation. When this happens, individuals may notice a shortness of breath, coughing, throat irritation, and/or experience an uncomfortable sensation in their chest.

Some actions you can take to protect your health during periods of unhealthy air quality include:

  • Adjusting your schedule to avoid strenuous outdoor activity during the afternoon.
  • Avoid using aerosol products such as cleaners, paints, and other lung irritants.
