Title: Mercury and methylmercury in the river Yare, Norfolk (1986 - 1992) : executive summary (OI/420/9/A)
Author: National Rivers Authority Anglian Region
Document Type: Monograph
The discovery that eels taken from the River Yare in 1985 contained elevated concentrations of mercury, almost twice the 0.3 mg kg-1 limit set by the 1984 EEC Directive (Council of European Communities, 1984), prompted a detailed investigation into mercury contamination within the River Yare system. The contamination was historical, originating from an industrial source that discharged (under licence) quantities of mercuric halides and copper to the public sewer during the late 1960s to mid 1970s. The original discharge consent for the chemical company permitted the emission of 2000 kg a-1 of mercury to the sewer.
