Concentrations of heavy metals and cyanide in water and sediments were determined from December 1974 to February 1976 in Yellowknife Bay situated in northern Canada. The bay receives a continuous discharge of liquid waste effluents from an operating gold mine. Arsenic reached a maximum concentration of 3100 mg kg(-1) in sediments near the waste source and decreased to minimum of less than 12 mg kg(-1) moving away from this area; corresponding ranges for Pb, Cu, Zn, Hg, and Fe were 13-800 mg kg(-1), 45-785 mg kg(-1), 23-935 mg kg(-1) 35-505 mg kg(-1) and 1.9-6.3% respectively. Although most pollutants were recorded at low levels in the water, arsenic and copper rose to 0.75 and 0.29 mg L(-1) coincident with maximum discharge from the waste source. Overall, water movement (generated by inflowing rivers and wind) was the most important factor governing the distribution of metals in the bay. Although surrounding islands also restricted the movement of pollutants through the bay, water depth, slope of the bottom and organic content of the substrate did not have a measurable impact on concentrations in sediments.
1974年12月至1976年2月，对位于加拿大北部的耶洛奈夫湾的水和沉积物中的重金属及氰化物浓度进行了测定。该海湾持续接收来自一座正在运营的金矿的液体废物排放。在靠近废物源的沉积物中，砷的浓度最高达到3100毫克/千克（-1），从该区域向外移动时降至最低，低于12毫克/千克（-1）；铅、铜、锌、汞和铁的相应范围分别为13 - 800毫克/千克（-1）、45 - 785毫克/千克（-1）、23 - 935毫克/千克（-1）、35 - 505毫克/千克（-1）和1.9 - 6.3%。尽管水中大多数污染物的含量较低，但砷和铜在废物源最大排放量时分别升至0.75毫克/升（-1）和0.29毫克/升（-1）。总体而言，水的流动（由流入的河流和风产生）是控制海湾中金属分布的最重要因素。尽管周围的岛屿也限制了污染物在海湾中的移动，但水深、底部坡度和底物的有机含量对沉积物中的浓度没有可测量的影响。
