Air pollution is linked to a number of health conditions, including heart disease, cancer and cognitive decline. These effects depend on the cause of air pollution. And not everyone is exposed to equally bad air quality.

Researchers from the University of Washington examined disparities in exposure to six major air pollutants in 1990, 2000 and 2010 by comparing atmospheric models. Level of pollution census data—where people live, racial/ethnic background, income status, etc.

Overall pollutant levels have declined since 1990, the team said, but regardless of income level, races of color may be more exposed to all six pollutants than whites across the continental United States. High is shown.

The researchers announced these results on December 15. Environmental hygiene approach.

“This is the first time anyone has comprehensively examined all of these major pollutants and observed how they change over time and space,” said a citizen from the University of Washington and others. Environmental engineering ..” This paper is an opportunity to recognize that while all communities are unique, there are some factors that are repeated over and over again across our country. State by state, environmental justice. No place without concern Not there. “”

A researcher in the past indicated that Americans of color were exposed to high concentrations of nitrogen dioxide (No.)2), external pollutants from automobiles and trucks in two census years 2000 and 2010.

Currently, the team is expanding their research to look at five additional pollutants that are harmful to our health. Carbon monoxide (CO), ozone (O.)3), sulfur dioxide (SO2) and particulate matter—both large particles (PM10) such as dust and pollen and small particles (PM2.5) such as molecules from vehicle exhaust. For all pollutants except PM2.5, the researchers extended the number of census years surveyed to 1990 and the Clean Air Act was enacted. Revised to address air pollution and emissions..

“There have been a lot of improvements,” said lead author and UW PhD student Jiawen Liu in civil engineering and environmental engineering. “But 20 years later, these disparities continue.”

To obtain annual air pollution data, the researchers used a model that included pollution estimates from multiple sources, including satellites and data from Environmental Protection Agency monitoring stations. These levels were then mapped to census demographic groups—including 4 race/ethnic categories (Black, Asian, Hispanic, White) and income—each pollutant in each group across the U.S. mainland and the state of Washington, D.C. Determines the estimated risk for

For each location, the team calculated both absolute and relative parallax. To account for absolute disparities, the researchers subtracted each group’s pollution exposure from the state’s average exposure. The team determined relative disparity by dividing absolute disparity by the national average risk.

“The relative disparities allow us to compare pollutants,” said Liu, a UW master’s student in biostatistics. “Each pollutant has a normal range of exposure, but when this is divided by the average, it provides a basis for the extent or magnitude of the asymmetry teeth.”

Disparities varied from place to place, but racial/ethnic minority groups showed the highest levels of exposure to all years and pollutants. Despite the overall clean air, this trend continued into 2010.

According to the researchers, one of the limitations of this approach is that the pollution model reflects the national average and may not be good at capturing heterogeneous pollution events in some communities.

“In short, our research shows that these inequalities do exist,” Liu said. “We are trying to get people’s attention and show what is happening right now. We hope this information will inspire change.”

“We need to document it,” Marshall said. “It may be new scientific literature but what affects the community most is not new to air pollution .. These communities have said this message for a long time. And it is important to bring humility to our research.”
