There is growing concern about possible effects of exploitation of the Alberta Oil Sands on the ambient environment, including possible effects on populations of fishes in the Athabasca River and farther downstream in Lake Athabasca and the Slave River. In the present study, concentrations of metals in dorsal muscle tissue of 5 fish species—goldeye, northern pike, walleye, whitefish, and burbot—from the Slave, Peace, and Athabasca Rivers were quantified. A suite of 25 metals including As, Hg, Se, Tl, and V was analyzed. Most metals exhibited no significant variations in concentration among locations. Concentrations of 5 metals, As, Hg, Se, Tl, and V, revealed significant variations among locations and were of sufficient magnitude to be of interest. Concentrations of Hg did not vary significantly among locations; however, because it was detected at concentrations of concern and the use of the selected fishes was a local source of food for humans and pets, it was of interest. Concentrations of As, Se, Tl, and V in dorsal muscle of certain fishes in the farthest downstream sites on the Slave River were greater than those in the same tissues and species in the farther upstream sites on the Peace and Athabasca Rivers. This phenomenon was most prevalent with Tl and to a lesser extent with As and Se. Nevertheless, concentrations were not of concern for the health of human consumers. Although metals did not appear to be increased in fish in the Alberta Oil Sands region in the present study, further research is needed to understand the potential impacts.

加拿大北部阿萨巴斯卡河和奴河的鱼类中金属的浓度。

人们越来越关注开采艾伯塔省油砂对周围环境的可能影响,包括对阿萨巴斯卡河以及阿萨巴斯卡湖和奴河下游的鱼类种群的可能影响。在本研究中,定量分析了奴隶河,和平河和阿萨巴斯卡河中5种鱼类(金眼鱼,北梭鱼,角膜白眼鱼,白鲑和独眼鱼)的背肌组织中的金属浓度。分析了25种金属,包括As,Hg,Se,Tl和V。大多数金属在位置之间的浓度没有显示出明显的变化。5种金属的浓度(As,Hg,Se,Tl和V)显示出位置之间的显着变化,并且其大小足以引起人们的关注。各地汞的浓度变化不大;然而,因为它是在关注浓度下检测到的,并且使用选定的鱼类是人类和宠物的本地食物来源,所以它很受关注。在奴隶河最下游位置的某些鱼类的背肌中As,Se,Tl和V的浓度大于和平河和阿萨巴斯卡河较上游位置的相同组织和物种中的As,Se,Tl和V的浓度。这种现象在T1中最普遍,而在As和Se中则较小。然而,浓度并不影响人类消费者的健康。尽管在本研究中,阿尔伯塔省油砂地区的鱼类中金属似乎没有增加,但仍需进一步研究以了解其潜在影响。这很有趣。在奴隶河最下游位置的某些鱼类的背肌中As,Se,Tl和V的浓度大于和平河和阿萨巴斯卡河较上游位置的相同组织和物种中的As,Se,Tl和V的浓度。这种现象在T1中最普遍,而在As和Se中则较小。然而,浓度并不影响人类消费者的健康。尽管在本研究中,阿尔伯塔省油砂地区的鱼类中金属似乎没有增加,但仍需进一步研究以了解其潜在影响。这很有趣。在奴隶河最下游位置的某些鱼类的背肌中As,Se,Tl和V的浓度大于和平河和阿萨巴斯卡河较上游位置的相同组织和物种中的As,Se,Tl和V的浓度。这种现象在T1中最普遍,而在As和Se中则较小。然而,浓度并不影响人类消费者的健康。尽管在本研究中,阿尔伯塔省油砂地区的鱼类中金属似乎没有增加,但仍需进一步研究以了解其潜在影响。这种现象在T1中最普遍,而在As和Se中则较小。然而,浓度并不影响人类消费者的健康。尽管在本研究中,阿尔伯塔省油砂地区的鱼类中金属似乎没有增加,但仍需进一步研究以了解其潜在影响。这种现象在T1中最普遍,而在As和Se中则较小。然而,浓度并不影响人类消费者的健康。尽管在本研究中,阿尔伯塔省油砂地区的鱼类中金属似乎没有增加,但仍需进一步研究以了解其潜在影响。2020年《环境毒理学》; 39:2180-2195。©2020 SETAC
