"The volume of toxic  chemicals that were released into the environment or sent for disposal in 2007  dropped 5 percent compared with 2006, the Environmental Protection Agency said  Thursday. But concealed within the overall numbers was good and bad news. For  example, the volume of released or disposed 'persistent, bioaccumulative and  toxic chemicals,' substances like lead, dioxin, mercury and PCBs, was up  slightly, the agency said. Most of those releases were not to air or water, the  agency said, meaning that the material was mostly buried in landfills, injected  into deep wells or held in impoundments. The number given for PCBs was up by 40  percent, but 'it's good news,' said Michael P. Flynn, acting deputy assistant  administrator for the Environmental Protection Agency's Office of Environmental  Information. The E.P.A. banned production of PCBs 30 years ago, so pounds  counted now, Mr. Flynn said, represent electrical transformers or other  equipment being taken out of service and PCBs disposed of in qualified  facilities."
