Samples of moose (N = 431) and white-tailed deer (N = 225) liver and kidneys were collected during the 1985 hunting season from 14 zones south of the 50 degree latitude in Québec. Regional differences in cadmium level in the liver were detected and three homogeneous areas were delineated for each species. Uptake was greater for moose than for deer: in the liver, mean concentrations were 2.9-15.9 mg kg-1 (dry weight) for moose and 0.8-2.6 for deer, depending on the area and sex; in kidneys, means ranged between 31.8-100.5 and 20.9-39.0 mg kg-1, respectively. Female moose had lower levels than bulls. Less affected moose, in eastern Québec, contained cadmium concentrations comparable to the highest values measured in Scandinavia. Cadmium uptake in deer was on the same level or higher than in the United States. Our results indicate a widespread presence of this heavy metal in the environment that may be linked to acid precipitation. We do not recommend consuming wild cervid liver or kidneys in Québec for the moment. Further research is needed on the overall mechanisms involved in the cadmium contamination of the environment and on the actual intake of this metal in the human diet.
1985年狩猎季节期间，从魁北克省北纬50度以南的14个区域采集了驼鹿（N = 431）和白尾鹿（N = 225）的肝脏和肾脏样本。检测到肝脏中镉含量存在区域差异，并为每个物种划定了三个同质区域。驼鹿对镉的摄取量高于鹿：在肝脏中，根据区域和性别不同，驼鹿的平均浓度为2.9 - 15.9毫克/千克（干重），鹿为0.8 - 2.6毫克/千克；在肾脏中，平均浓度分别在31.8 - 100.5毫克/千克和20.9 - 39.0毫克/千克之间。雌性驼鹿的镉含量低于雄性。魁北克东部受影响较小的驼鹿体内镉浓度与斯堪的纳维亚半岛测得的最高值相当。鹿体内的镉摄取量与美国相当或更高。我们的研究结果表明，这种重金属在环境中广泛存在，可能与酸雨有关。目前我们不建议在魁北克食用野生鹿类的肝脏或肾脏。需要进一步研究环境镉污染的整体机制以及人类饮食中这种金属的实际摄入量。
