When School is an Asthma Danger Zone

But what can be done about this? In California, where over 10 percent of schoolchildren have asthma, and nearly 12 percent suffer breathing problems at least once a week, the state government took action. Back in 2003, it passed a law that says schools can’t be built within 500 feet of a major highway, unless there’s no other place to build, or unless the school board can prove that the air students and teachers are breathing is not risky.

Passing the law was the easy part; implementing it is another story. The Los Angeles Unified School District (LAUSD) was midway through a decade-long building plan to construct more than 100 schools when the new law passed.

By 2003, the LAUSD had already commissioned the design of one school in Hollywood – in an old TV studio right beside a major freeway. Helen Bernstein High School was supposed to relieve pressure on the overcrowded high schools in the middle-class neighborhood. Even before the roadway-pollution law, there were concerns about the close association of kids and traffic. The school board installed state-of-the-art filtration systems to clean the air in the $177 million school. It was a good compromise, says Scott Folsom, a retired filmmaker and former president of L.A.’s Parent Teacher Association. But in a state teetering on the financial brink, he wonders whether the government will maintain the air systems properly: “It’s hard to spend no money wisely.”

Since 2001, the LAUSD has built 101 schools. Two of them were relocated prior to construction because of the roadway-pollution law, and 11 were built near highways, with air-purifying systems to protect the children. Folsom argues that in a big city, you have to be realistic. “You can’t build away from streets. You can’t build in a perfect situation.”

There are still 180 schools in California sitting close to a major highway. Many of them are located just east of Los Angeles, where over four million people live in the vast urban area of Riverside and San Bernardino.

It was once a broad valley of dairy farms and vineyards set against an idyllic backdrop of mountains. No more. The Inland Empire, as the area is now known, has turned into a transportation hub of freeways and railways. Smog blots out the mountains, and families have to put up with some of the worst particulate air pollution in the country. Asthma is commonplace.

“We’ve created a major health crisis,” says Penny Newman, a community activist. Newman and fellow activists pressed authorities to install air filtration systems at five local schools, at a cost of $1 million. Air filters are also being installed in 40 schools between L.A. and the port. These filters cut most of the pollution out of the indoor air – but there’s nothing they can do about the outdoor air.

If you travel thousands of miles north and east to Toronto, you’ll find a similar problem. Over 11 percent of children in Grades 1 and 2 have asthma, according to a survey led by Toronto’s Hospital for Sick Children. But authorities have yet to pay any attention to the growing evidence that kids who live and go to school near transportation corridors are the most likely to have asthma symptoms.

In fact, they’re planning to make it worse. Ontario is set to increase diesel traffic on an 18-mile rail corridor that will link Toronto’s Pearson International Airport and the downtown railway station. There are 75 schools and numerous daycare centers along the tracks.

The trains will be powered by “clean diesel,” which emits far less soot and fumes than most cars and buses, but the trains will still put more soot in the air, and that’s bound to affect children living and learning along the corridor.

A couple of blocks from the tracks, on a prime spot by the waterfront, a daycare and an elementary and high school share a building. On one side, there’s a fine view of Lake Ontario. But behind the school, where children play on the concrete playground, you can see and hear the rumble of vehicles speeding along the Gardiner Expressway.

“We are concerned about the pollution and it doesn’t appear that the city or the province or the federal government care much about the pollution created in the neighborhood,” says Peter Morgan, a high school teacher. “There is next to no monitoring of traffic violations, in particular the idling.” Yet the province “could care less,” he says.

The emerging results of the schools research are bound to trouble any parent who’s sending an asthmatic child to school near a highway. But what are they supposed to do? What if your child’s school is already established near a highway?

University of Cincinnati professor Sergey Grinshpun has faced this dilemma. Grunshpun is the author of the report showing that 30 percent of U.S. schools sit close enough to highways to be affected by soot and fumes. The school he found for his own two kids is an example of that statistic. “What choice did I have? Move the kids to a less good school?” he says. He opted for the highway. As it turned out, neither child developed asthma.

Concerns about schools proximity to highways will only become a bigger issue and get on the school boards and politicians’ radar as this type of research gains media attention and as parents lobby for change. In the meantime, Grinshpun offers this practical advice as both a father and an expert: If your child’s school is beside a highway, check into its ventilation system. And do at least limit your child’s outdoor school activities during the rush hour.
