Aquatic Toxicity Associated with Diamond Ore (Kimberlite) Mining (Enviro-Test Laboratories, December 1998)
This comprehensive toxicity study examines the aquatic effects of kimberlite ore from BHP Diamonds Inc.'s diamond mining operations in the Northwest Territories. The study includes acute and chronic toxicity testing on multiple species, toxicity identification evaluation, and 30-day fish exposure experiments assessing sublethal effects, concluding that the water licence limit of 25 mg/L kimberlite discharge is adequate for environmental protection.
