To determine the levels of particle matter (PM2.5) and ozone in the air in Rhode Island and to determine the cancer risks associated with toxic substances in air pollution.
Key Information: PM2.5 and Ozone are measured in micrograms per cubic meter, and are based on both monitored and modeled data. Average air concentration estimates are provided for 1, 3-butadiene, acetaldehyde, benzene, carbon tetrachloride, and formaldehyde. Cancer risk estimates are also provided for these pollutants.
Collection Period: Ozone and PM2.5 data are available from 2001 to 2014. Air toxics are available for 2005 and 2011.
Rhode Island Numbers
The number of days that Rhode Island’s air has unhealthy levels of ozone is going down.
The average concentrations of fine particles in the air have dropped by almost 50 percent since 2001.
