"Noranda Mines Limited started operation of Bell Mine on the Newman Peninsula of Babine Lake in 1972. The mine stopped operations in 1982 and resumed in 1985. A previous report was produced in 1985 to address the mine discharges during the close-out period. The present report is intended to address the state of the environment in Babine in light of a report sponsored by the company in 1988. Various major sub-basins of the lake close to the mine were surveyed; supplementing information provided by the company. Work included examination of benthic invertebrates, surface sediment chemistry, and sediment cores. In addition, sediment sequential extractions and sediment bioassays were performed"--Introduction, page 1.
