Pollution is, rather than harmful to health, directly fatal. Not in vain, this air pollution is responsible every year for the death of more than 25,000 people in our country alone. In fact, the inhalation of particles in suspension with a diameter not exceeding 2.5 microns - PM2,5, which are considered the best indicator of urban pollution and whose small size poses a greater risk to the health of humans - causes diseases such as, among others, cardiovascular, respiratory and cancer. In fact, a new study led by researchers at the University of Birmingham (UK) warns that each increase of 10 micrograms per cubic meter of air at PM2.5 levels leads to a 22% increase in the risk of mortality by any Type cancer in the population over 65 years. A very important aspect to keep in mind given that, to date, 1 in 3 Spaniards are forced to breathe contaminated air.

As Thuan Quoc Thach, co-author of this research published in the journal Cancer Epidemiology, Biomarkers & Prevention, explains, "Long-term exposure to particulate matter has been mainly associated with mortality from cardiopulmonary causes and cancer of lung. And the number of studies in which the ratio of these particles to other types of cancer has been evaluated is very small. However, we suspect that these particles could have an equivalent effect on the tumors of the rest of the organism.
