chemical exposure lawsuit against three companies over potential harm caused by high levels of PCBs.
The lawsuit seeks damages on behalf of Lexington and other school districts of Massachusetts that have school buildings affected by polychlorinated biphenyls (PCBs) made by Pharmacia Corp., Solutia Inc., and Monsanto Co., according to Boston.com.
The suit alleges that the makers of PCBs were aware of the risks that the chemical posed to public health and the environment when it was being used in the construction of schools spanning almost three decades, starting from the 1950s. The class action seeks to represent Massachusetts schools that were built between the 1950s and the 1970s. Monsanto says that the suit lacks merit.
The manufacturing and use of PCBs was banned by Congress in 1976.
