Liverpool Bay supports a productive commercial fishery yet at the same time is also used as a site for the disposal of waste by dumping, as well as receiving discharge of effluent from pipelines, rivers and estuaries. This paper summarizes the results of the monitoring programme of fish and shellfish quality in Liverpool Bay carried out in recent years including two special surveys conducted in and around the sewage sludge dumping site in 1980 and 1981. The concentrations of trace metals are discussed in relation to inputs into the bay. Mercury concentrations in fish appear to vary with the two major imputs (sewage sludge dumping and industrial discharges). There is no evidence of widespread elevated concentrations of cadmium, lead, zinc and copper in fish and shellfish from the bay but there is some evidence of local contamination by these metals. None of the elevated concentrations of metals found appear to be significant from a public health viewpoint. |
