Industry Report to the Community

Pasminco Metals-Sulphide Pty. Ltd.
Community Report Extract from Issue 4, Nov 1992

The Public Health Unit (PHU) conducted a review of research into heavy metal concentration in fish in Lake Macquarie, in response to requests from residents.

Furner (1979) found liver (not flesh) concentration of lead in mullet and bream to be markedly higher in Cockle Creek samples than for the rest of Lake Macquarie. Only marginal increases of lead in the muscle of the same fish was found. This follows research by Wharfe and Vanden Brock (1977) which notes that heavy metals tend to accumulate in the soft organs (liver, kidney, spleen).

The Environment Protection Authority and PHU warned that molluscs and oysters should not be eaten from any estuary (including Cockle Creek) entering Lake Macquarie because of possible pesticide contamination from urban runoff. Commercially grown oysters, however, do not pose a risk.
