Anglers in Maryland will soon get new warnings about fishing in polluted waterways.
The signs, in English and Spanish, will advise anglers to avoid or limit the amount of fish they eat.
The Baltimore Sun reports that the Maryland Department of the Environment is providing signs to Baltimore County that indicate fish in certain waterways could have mercury, PCBs, and pesticides. The county has identified 20 locations for the new signs and is looking at other possible sites.
The department recently provided similar signs to Prince George's County to put near the Anacostia River.
All people are advised to aviod eating any blue catfish, channel catfish or common carp caught in the Anacostia River in Prince George's and Montgomery counties.
