Municipal Water and Sewage Enterprise in the Capital City of Warsaw confirms the use of fish and mussels for biomonitoring. They explain that they use biomonitoring at Warsaw Waterworks to increase the safety of the water treatment process. The mussels of the sharpened scallop species used are very sensitive to water pollution.
