On the whole, the map, from HealthyEnviron, shows the city has a moderate air quality score of 37. Areas needing improvement include “particulate matter, nitric oxide, carbon monoxide and ground-level ozone.”

However, there are some parts of the region that suffer from exceedingly poor health, the map shows. Those communities include: Almeda, Alief, Braeburn, Greenspoint, Northside, Acres Homes and East Downtown.

Reasons cited for the low rankings include high levels of carbon monoxide and population obesity.
