Pollution, disproportionately affects communities where economically disadvantaged people and Hispanic, Black and Asian people live.
. They analyzed these data across small geographic regions, called census tracts, that are defined by the U.S. Census Bureau. In a proof-of-concept project, they used this approach to analyze initial disparities in Houston, and later applied these data-gathering methods to study daily disparities over New York City and Newark, New Jersey.
In these cities, as in New York City and Newark, the researchers also analyzed the data to see whether they could identify any links with wind and heat — both factors that are expected to change as the world warms. Although the analysis is not yet complete, the team has so far found a direct connection between stagnant air and uneven pollution distribution, which was not surprising to the team because winds disperse pollution.
Pusede hopes to see this type of analysis used to support communities fighting to improve air quality. “Because we can get daily data on pollutant levels, it’s possible to evaluate the success of interventions, such as rerouting diesel trucks or adding emissions controls on industrial facilities, to reduce them,” she says.A recorded media briefing on this topic will be posted Monday, Aug. 22, by 10 a.m.
