Air Quality Alert - Health Advisory Ozone

Published on Thursday, July 27, 2023

PROVIDENCE – The Rhode Island Department of Environmental Management is predicting that air quality will reach UNHEALTHY levels during the afternoon and well into the evening on Friday, July 28. The alert is being issued statewide due to elevated ground-level ozone concentrations. The highest readings will be along the southern portions of Rhode Island along the immediate coastline. Fine particles readings are expected to reach MODERATE statewide, with some light Canadian fire smoke moving in after mid-day.  Ozone is a major component of smog and is formed by the photochemical reaction of pollutants emitted by motor vehicles, industry, and other sources in the presence of elevated temperatures and sunlight.  

The Rhode Island Department of Health warns that unhealthy levels of ozone can cause throat irritation, coughing, chest pain, shortness of breath, increased susceptibility to respiratory infection, and aggravation of asthma and other respiratory ailments.  These symptoms are worsened by exercise and heavy activity. Children, the elderly, and people who have underlying lung diseases, such as asthma, are at particular risk of suffering from these effects.  As ozone levels increase, the number of people affected and the severity of the health effects also increase.

To avoid experiencing these effects, limit outdoor exercise and strenuous activity and stay in an air-conditioned environment, if possible, during the afternoon and evening hours when ozone levels are highest.  Schedule outdoor exercise and children’s outdoor activities during the morning hours, as ozone does not typically form until after mid-day.  Individuals who experience respiratory symptoms may wish to consult their doctors.

Rhode Island residents can help reduce air pollutant emissions.  Limit car travel and the use of small engines, lawn motors, and charcoal lighter fuels.  Travel by bus or carpool whenever possible, particularly during high ozone periods. 

Air quality can change throughout the day. Use AirNow.gov or download the AirNOW application for smartphones to check the current air quality and decide if it is a good time to be active outdoors.
