An Air Quality Alert Action Day has been issued for the area.
The Fall River area is expected to have a 125 AQI Saturday which is unhealthy for sensitive groups.
The conditions may cause health affects among sensitive people. Those most at risk are children, other active people, the elderly, and those with existing respiratory illnesses.
MassDEP has called an Action Day for poor air quality and recommends limiting strenuous activity, taking public transportation, or working at home, if possible.
The area also has an Excessive Heat Warning this weekend.
