A new study at Columbia University’s Mailman School of Public Health reveals differences in beauty (PM)2.5) events between Indian Indians (AI) and non-AI of US PM2.5 is one of the pollutants designed by the American Environmental Protection Agency (EPA), with a current annual rate of 12μg / m3. Events below in PM2.5 Discussions abound among non-AI users compared to AI environments. Although AI local governments have low PM2.5 With more than a dozen non-AI districts in 2000, by 2018, their levels are even higher. With so many U.S. air pollution surveys conducted in cities, this is the first study to provide detailed information on the magnitude of air pollution and its impact on health among rural AI communities. The search results are published in American Journal of Public Health.

“Our findings underscore the need to strengthen air pollution regulations and implement prevention in tribal areas and areas inhabited by AI people,” said Maggie Li, Ph.D. candidate in the Department of Environmental Health at Mailman Columbia School, and first author. “Still, understanding the PM2.5 Weight loss is limited in AI communities, which contributes to air pollution epidemiological studies which includes this population in the painful United States “

The researchers compared the PM of the environment2.5 Average positions and events in AI-population vs. non-AI-population districts in the US contiguous from 2000 to 2018. They conducted research at the district level, the most appropriate unit to inform the process. Data on population and household income were obtained from the 2010 US Census.

The average dose is 1.46 μg / m3 below for the PM product2.5 in populated AI districts and non-AI districts in 2000; however, by the end of the study period, PM2.5 The population in AI counties is significantly higher compared to non-AI districts. In 2018, concentrations were on average 0.66µg / m3 higher in AI sub-sectors than non-AI sub-sectors. “Although we noticed the average PM2.5 the concentration was higher in non-AI areas in the original and in most study periods, the gap between AI- and non-AI decreased over time; after almost 2015, the average PM2.5 Li added that there has been an increase in population in AI counties.

Short-term and long-term manifestations for genetic components 2.5µm (PM2.5) increases the risk of cardiovascular disease, among others health consequences. In the United States, poorer communities often face a higher PM2.5 exposed levels. They bear the brunt of unpredictable diseases, even at levels below the air quality standards set by the US Environmental Protection Agency.

“Our findings are based on current research showing that economically poor communities are exposed to a wide range of unsafe environmental hazards, such as pollution.2.5 and air pollution, but research quantifying the appearance of air pollution and its impact on public health has diminished, “said Marianthi-Anna Kioumourtzoglou, ScD, assistant professor of environmental sciences at Mailman Columbia School, and great writer. ”These communities are already facing a crisis. major diseases related to environmental pollution, for example, to high levels of mining and water pollution in ethnic countries. “

Cardiovascular disease, one of the consequences associated with the appearance of PM2.5, and a major cause of death in the AI ​​population, occurring at a higher rate than the white population. Ana Navas-Acien, MD, Ph.D., professor notes that “There is an urgent need for further research on the health effects associated with the appearance of air pollution in the AI ​​population, and to work to ensure that observed inequality can be eliminated, ”said Ana Navas-Acien, MD, Ph.D., professor. and environment health Science at Mailman Columbia School, and senior author.
