The CSIC recalls the relationship between pollution and mortality following the statements of Díaz Ayuso

After the controversial statements of the president of the Community of Madrid, Isabel Díaz Ayuso, in which says that "nobody has died" or "is going to die" from pollution, the Higher Council for Scientific Research (CSIC) has posted a message on Twitter in which it recalls that the relationship between pollution and the risk of mortality is a reality.

"An international study confirms the relationship between pollution and the risk of mortality. An analysis in 652 cities shows a higher risk of mortality after exposure even to small concentrations of urban air pollution," said the CSIC.

In that same message, the public body links the press release they issued in August 2019 about the study to which it refers and in which the associate professor of the Institute of Environmental Diagnosis and Water Studies of CSIC Aurelio Tobias participated.

As they explain in the web portal, the study represents the largest epidemiological evaluation carried out to date on the short-term effects of air pollution, and researchers have collected time series data from 652 cities in 24 countries in the period 1986 -2015.

They specify that. on average, "an increase of 10 micrograms / m3 in inhalable particles (PM10) - capable of penetrating into the lungs - and fine (PM2.5) - which can penetrate into the bloodstream - is associated with an increase in mortality at short term of 0.44 percent and 0.68 percent. "

From the CSIC they have also made a thread in their Twitter account in which they link several newspaper articles on how it affects pollution to people, and insist that the fine particles present in the polluted air enter the body through the lungs and affect health in various ways: "In the brain, heart, liver, placenta and virtually all organs."

This string of tweets comes after Díaz Ayuso said in an interview in the Cadena Ser that "nobody has died" due to pollution in Madrid as the public health alarm is not "real". The president stressed that "Madrid is doing things correctly" to seek more and more "greener and cleaner cities."
