ATSDR Releases Report about Exposure to PCBs at Oak Ridge Reservation, TNMonday, December 04, 2006 Geographic Location: Oak Ridge, TNExposure to polychlorinated biphenyls (PCBs -- a chemical used as a coolant and lubricant in electrical equipment) from the Oak Ridge Reservation does not pose a public health hazard, says the public health assessment released by the Agency for Toxic Substances and Disease Registry (ATSDR). However, as a public health precaution, the agency suggests residents limit eating certain types of local fish. ATSDR conducted the report to evaluate whether past and current exposures to PCBs in the air, fish, geese, turtles or nearby off-site waterways could cause illness. The waterways examined in the report are the Clinch River, East Fork Poplar Creek, Poplar Creek, Lower Watts Bar Reservoir and the Tennessee River. Based on the levels of PCBs detected in fish, geese and turtles, it is safe to eat up to one meal of any type of fish per month. One adult fish meal is considered to be 8 ounces (1/2 pound). Children are assumed to eat one-third this amount. However, ATSDR suggests limiting the consumption of certain species of fish:
PCBs in local waterways came from plant operations at the Oak Ridge Reservation's Y-12, K-25, X-10 and S-50 sites where a large amount of electrical energy required the use of the chemical. During these operations and because of former waste disposal practices, oily PCB fluids were spilled onto the ground and released into nearby creeks and ponds. The public health assessment is available to the public for review and comment, however ATSDR will not be able to address comments or make this report final unless additional U.S. Department of Energy funds are received. Community members are encouraged to submit comments during the public comment period, as public comments are an important part of the public record. The public health assessment is available at the following locations:
