Schools across the United States are being urged to replace the electrical components in the older light fixtures. The light fixtures pose a threat of contamination that could lead to cancer later on in life. The Environmental Protection Agency say that the light fixtures contain a man- made chemical called polychlorinated biphenyls(PCBs). The PCBs can do harm to the reproductive and immune systems in the body and if they build up enough even cause cancer. Schools are to remove the electrical components immediately if they are leaking the PCBs.
