SAUGUS, Mass. -- There are growing health concerns at a local elementary school after one teacher tested positive for asbestos.

Parents fear the asbestos could also make their kids sick, but they said the school isn't doing anything about it.

NewsCenter 5's Shiba Russell reported that the big question for parents at the Lynhurst Elementary School in Saugus, Mass., is whether the air inside the school is safe to breathe.

Eight years ago, the school laid down new floor tile to cover asbestos and now that newer tile is also cracking, spurring parents' concerns over whether students will be exposed.

"Our fear now is that it's an unhealthy, unsafe for our children to go on a daily basis, five days a week, six hours a day. Teachers have asked for tennis balls for the bottom of their chairs so that they don't crack tiles," parent Paul Arnold said.

City leaders, however, said that tests indicate the school is safe.

"Air quality tests in the school have proven negative. In the past, most recently in 2005, and in the last several months, we've completed air quality tests for mold and other airborne bacteria and those tests also proved negative," town manager Andrew Bisignani said.

Several Linhurst teachers, however, told NewsCenter 5 that parents should be worried. Teachers at other aging Saugus schools are also worried. They said that faculty and students have been reporting symptoms associated with asbestos exposure.

"Sinus infections, pneumonia, liver. All kinds of issues coming up with the teachers, children coming in whose parents say they're getting sick when they're in the building every day," teacher Diane Walsh said.

The parents said they plan to raise their concerns again at a school committee meeting Thursday night.
