Screening the Levels of Lead, Cadmium, Arsenic, Chromium, Zinc, Mercury, and Thallium in the Traditional Food-Lobster of Eel River Bar First Nation
The purpose of this project was to examine the concentrations of heavy metal contaminants: cadmium, lead, arsenic, and mercury as well as chromium, thallium and zinc within the lobster traditionally consumed by the Mi’gmaq of Eel River Bar, New Brunswick.
A total of 44 lobsters we tested, where 22 were cooked and 22 were raw. Due to high laboratory analysis costs, a decision was made to test both lobster meat and tomalley together for each lobster.
The mean concentrations for all 44 lobsters were found to be lower than the maximum allowed levels according to International standards for arsenic, cadmium, lead, and mercury. However, when observing the levels of heavy metals in individual lobsters, five (5) lobster had levels of cadmium that were in excess of its respecting International standard of 0.5 mg/kg set by the Commission of the European Communities. There were no International standards identified for chromium, thallium and zinc in lobster. There was no observed correlation on the concentrations of heavy metals between raw and cooked lobster.

Kelt tagging started on the Restigouche River earlier this week, as staff from the Gespe’gewaq Mi’gmaq Resource Council (GMRC) begin outfitting Atlantic salmon with either acoustic monitors or satellite tags. The tagging process will help us understand the migration patterns of this species as they move from the rivers into the Atlantic Ocean. The acoustic receivers have a specific identification number, and as the kelt migrates, acoustic receivers deployed from the Restigouche River, throughout the Bay of Chaleur, Newfoundland and Labrador will record their incredible journey. This tagging research will also tell us about their survival rates. Kelts, are an important part of the Atlantic salmon life cycle because they have successfully returned from the ocean to spawn in the river and pass along their strong genes.
