Spain practises outside before World Cup final Smoke fills the air in New Jersey

With the sun obstructed by haze, Spain’s players practised on Thursday ahead of the World Cup final outside in northern New Jersey while air conditions are hazardous because of smoke from Canadian wildfires.

It was not clear how fast-paced a practice Spain held. Media members are only able to observe the first 15 minutes of what was scheduled to be a hour-long session in East Hanover.

Argentina remained in the Atlanta area to work out less than 24 hours after rallying to beat England and reach the final for a second consecutive tournament. Marietta, Georgia, is far enough south to avoid the effects of the fire, which are being windblown to the southeast from northern Ontario, triggering warnings from the United States Midwest through the Northeast.

Officials urged people to stay inside or wear masks outside as air quality reached unhealthy to hazardous levels, meaning it’s unhealthy for anyone, regardless of health conditions. Experts expressed concern over holding practice outdoors.

“These are high-level athletes who are moving a lot of air through their lungs during every practice in every game, and really they shouldn’t be practising outside if the air quality levels are at hazardous sort of ranges for wildfire-related air pollution,” said Dr. Courtney Howard, an emergency room physician and Global Climate and Health Alliance official.

“That’s the time to schedule a practice inside. You could put an N95 mask on them, but trying to make sure that everybody’s mask is well-fitted, I suspect that’s not the best choice. I would go find an air-conditioned indoor facility that’s a clean-air shelter.”

Messages sent to FIFA and the Spanish Football Association asking whether that was considered or possible were not immediately returned. The smoke is expected to clear the area well before the championship game on Sunday in East Rutherford, New Jersey, with kickoff scheduled for 3 p.m.

The air quality in East Hanover on Thursday started early in the morning as “unhealthy” but got cleaner, so by mid-afternoon it was merely “unhealthy for sensitive groups”, according to the US Environmental Protection Agency’s Air Now monitoring system. Particle pollution in New Jersey on Thursday was more than seven times higher than the World Health Organisation standard. The forecast calls for an improvement to “moderate” for Sunday.

“It’s not healthy for anyone to be in the smoke, especially if you’re exercising,” Harvard School of Public Health environmental health research scientist Mary Johnson said. “You’re exchanging more air, so you’re being exposed to even more pollutants, and even healthy individuals at some point will have some type of health effect from the exposure to the smoke. So, even though these are healthy, young individuals, it’s not a good idea to be exercising in this type of environment.”
