New York, Aug 23 : If air pollution were removed as a risk for death, people in the world could live at least a year longer and in India, which is battling a severe air pollution, the benefit would be even more -- about 1.5 years, says study.

"Here, we were able to systematically identify how air pollution also substantially shortens lives around the world," said lead researcher Joshua Apte from The University of Texas at Austin in the US.

"What we found is that air pollution has a very large effect on survival -- on average about a year globally," Apte added.

For the study, published in the journal Environmental Science and Technology Letters, the researchers looked at outdoor air pollution from particulate matter (PM) smaller than 2.5 microns.

These fine particles that can come from power plants, cars and trucks, fires, agriculture and industrial emissions can enter deep into the lungs, and breathing PM2.5 is associated with increased risk of heart attacks, strokes, respiratory diseases and cancer.

The team used data from the Global Burden of Disease Study to measure PM2.5 air pollution exposure and its consequences in 185 countries.

They then quantified the national impact on life expectancy for each individual country as well as on a global scale.

"A body count saying 90,000 Americans or 1.1 million Indians die per year from air pollution is large but faceless," Apte said.

"Saying that, on average, a population lives a year less than they would have otherwise -- that is something relatable," he added.

In the context of other significant phenomena negatively affecting human survival rates, Apte said this is a big number.

"For example, it's considerably larger than the benefit in survival we might see if we found cures for both lung and breast cancer combined," he said.

"In countries like India and China, the benefit for elderly people of improving air quality would be especially large. For much of Asia, if air pollution were removed as a risk for death, 60-year-olds would have a 15 per cent to 20 per cent higher chance of living to age 85 or older," Apte said.

Barcelona (AP): Real Madrid slapped players Federico Valverde and Aurélien Tchouaméni with half-a-million-euro ($588,000) fines on Friday for their altercation during practice.

The massive fines came a day after the midfielders tussled when the team trained. Valverde said in a post on social media on Thursday that no punches were thrown. But Valverde knocked his head on a table and he suffered a small cut that required a brief hospital visit.

On social media, Valverde initially called it a “meaningless fight” with a teammate and said “everything has been blown out of proportion."

His employers, however, considered it a significant enough breach of team discipline to nail both Valverde and Tchouaméni with fines that bite even the bank account of a top soccer player. The half-a-million euro penalties reflect the reputational damage the club was enduring in a chaotic end to a disappointing season.

In a statement, the 15-time European champion said its disciplinary action was concluded after both players expressed to the club “their complete remorse for what happened and apologized to one another.”

Madrid added they also apologized to their teammates, the coaching staff and club supporters, as well as showing their willingness to accept whatever disciplinary action the club deemed “opportune.”

Tchouaméni was back training with Madrid on Friday, two days before they play at Barcelona in a clasico. Madrid has to win otherwise Barcelona will be crowned La Liga champion.

After being notified of the fine, he posted a public apology to the club and its fans on social media.

“What happened this week in training is unacceptable,” Tchouaméni wrote. "I say this while thinking about the example we are expected to set for young people, whether in football or at school.

“Above all, I am sorry for the image we projected of the club.”

Valverde was not at practice due to the head knock.

Both players are set to play in the World Cup next month, with Tchouaméni playing for France and Valverde for Uruguay. 

Chaotic end to a poor season

===================

The run-in between the players, who for seasons have played side by side in Madrid's midfield, came after they argued this week in previous training sessions. But tempers boiled over on Thursday. Spanish media was rife with reports that the players previously disagreed over the club's decision to let coach Xabi Alonso go after just months on the job.

It was not the only altercation involving Madrid players during training this week. Álvaro Carreras confirmed he was in a “minor” incident with a teammate. Spanish media said he and fellow defender Antonio Rüdiger got into a scuffle.

Álvaro Arbeloa, the coach who was promoted from Madrid's reserve team when Alonso was fired in January, will face tough questions on what went wrong inside the changing room when he gives a press conference on Saturday ahead of the clasico at Camp Nou.

Madrid is facing a second consecutive campaign without a major trophy amid rumors in the Spanish media that club president Florentino Pérez is considering bringing back Jose Mourinho to straighten out his underperforming team.
