American researchers have studied the consequences of pollution on mortality. They show that even when the rate is below the legal thresholds, polluted air still presents risks to health.

The reduction of air pollution is one of the major ecological issues of our time. To do this, pollution thresholds for each type of pollutant are established to determine the level of air quality. However, a recent study shows that even at levels below the thresholds established, polluted air still poses major risks to the health of people around the world, especially in countries where access to health services remains expensive.

A group of American researchers conducted a study to analyze the link between pollution and mortality, taking into consideration different levels of pollution. Their results show that the mortality rate varies according to the presence or absence of fine particles in the air and the concentration of ozone.

The study finds that short-term exposure to fine particles and ozone increases the risk of mortality, even when air pollution is below air quality standards. The result of the study was published in the Journal of the American Medical Association.

Each daily increase of 10 micrograms per cubic meter of air increases the risk of death by 1.42 per million people. Above all, the scientists have found that even on days with low pollution levels, the risks remain substantial. They calculated pollution levels for each area of ​​the United States. The most vulnerable people are the most affected by pollution and its consequences on mortality: elderly people or those with lung problems.

The scientists suggest revising air quality standards, at least in the United States. A suggestion that has no chance of having President Trump’s agreement in the current context.
