In "Pollution site being isolated" (Aug. 26) about the Hudson River controversy, you write that PCBs are "cancer-causing." More than 20 studies, mostly conducted by the federal Environmental Protection Agency and National Institute for Occupational Safety and Health, have failed to conclude that PCBs cause cancer in humans.
PCBs have only been associated with cancer through high-dose animal studies. And even this animal evidence is being reconsidered. In 1996, the EPA reduced the PCB cancer potency a factor by between 4 and 100.
