Health Risk AQHI At Risk Population General Population
Low Risk 1 – 3 Enjoy your usual outdoor activities. Ideal air quality for outdoor activities.
Moderate Risk 4 – 6 Consider reducing or rescheduling strenuous activities outdoors if you are experiencing symptoms. No need to modify your usual outdoor activities unless you experience symptoms.
High Risk 7 – 10 Reduce or reschedule strenuous activities outdoors. Children and the elderly should also take it easy. Consider reducing or rescheduling strenuous activities outdoors if you experience symptoms.
Very High Risk 10+ Avoid strenuous activities outdoors. Children and the elderly should also avoid outdoor physical exertion. Reduce or reschedule strenuous activities outdoors, especially if you experience symptoms.

Health Vulnerability Statement

All communities included in this report are designated as “underserved” by MDEnviroScreen. Notably, Turner Station, Cheverly, Cedar Heights, Curtis Bay, and areas near HCNR, and HU-B are further classified as “overburdened,” meaning they face a cumulative impact of three or more environmental or health stressors.

Critical sensitive population indicators (75th Percentile or higher):

Due to these compounding health disparities and socio-environmental stressors, the reported Air Quality Health Index (AQHI) represents a conservative baseline; the actual risk to residents in the tracts mentioned above is likely higher than the index alone suggests.
