The San Jose Mercury News reports:
LOS ANGELES—The nation's second-largest school district has dumped plans to build two new campuses near a freeway after concerns about the impact of air pollution on youngsters.
The Los Angeles Times says the L.A. Unified School District has halted plans to put a high school and middle school within 500 feet of Interstate 10.
More than 60,000 students already attend schools near freeways and five new campuses are being built.
Those buildings will have air filters to strip out road toxins but health experts say filters can't remove ultra-fine particles linked to asthma and bronchitis.
