Toxic Caulking in Schools 

Students and staff at hundreds of older schools across New England could be at risk for health problems because of toxic caulking in windows and masonry.That word comes from officials at the Environmental Protection Agency.They’ll soon be releasing guidelines to school officials and owners of other buildings on what to do about the problem.The agency says some caulk used in the 1960s and 1970s containspoly-chlorinated bi-phenyls, or PCBs, which were banned in the late1970s because of potential cancer risks. Officials say PCBs from deteriorating materials can end up in the air.The Boston Globe reports that the Massachusetts Department ofPublic Health is recommending that schools test their caulking andreplace it if it is deteriorating.
