The Department of Environmental Resources said Monday, relatively high levels of toxic chemicals known as PCBs have been found in carp and eels taken from the Schuylkill River.

DER and Fish Commission officials said the PCB levels were higher than the health limits set by the U.S. Food and Drug Administration.

Richard Boardman of DER's Bureau of Water Quality, said nobody should "make a steady diet" of fish from the Schuylkill, but that there was no reason to stop eating fish altogether.
