We took it a step further and also considered the populationвЂ™s vulnerability. вЂњAnd this is new because most other studies that have explored air pollution have really stopped the exposure, so they look at the difference in air pollution levels on the neighborhood scale and compare concentrations of pollutants with each other. вЂњWe examined inequality and air pollution-related health risks across Washington, DC on the neighborhood scale,вЂќ Anenberg said in an interview. Susan Anenberg, associate professor of environmental and occupational health and one of the newspaperвЂ™s authors, said the study found that although air pollution levels across the district had fallen, pollution-related health risks remained вЂњunevenly distributed,вЂќ the researchers indicated. The October study of air pollution and related health consequences, such as cancer, showed that sections 7 and 8, which make up the majority of southeastern DC, were home to the highest concentrations of PM 2.5, an air pollutant that was harmful. NASA released an online map showing how air pollution has affected black mortality in the district earlier this month from a study conducted by a Milken professor this fall. Milken Institute School of Public Health researchers conducted a study of how air pollution has affected black mortality rates in DC, which has received national attention.
