Traces of mercury and PCBs, or toxic chemicals, are widespread among sport fish in California's urban coastal waters, according to a report by the California Water Board.

The report said 19 percent of the coastline which was tested harbored fish with mercury in such high concentrations that they should not be eaten by children and young women.

Mercury and PCBs can cause cancer, nervous system and liver damage and developmental problems in children and reproductive issues.

The most elevated concentrations of mercury and PCBs were found in San Francisco and San Diego bays.
