The recent invasion of the Dressenid species, the quagga mussel, Dreissena bugensis, into Lakes Mead, Mohave and Havasu has raised questions about their ability to alter contaminant cycling. Mussels were collected from 25 locations in the three lakes. The overall average was 0.036 +/- 0.016 microg g(-1) Hg dry wt. The range of the three lakes was from 0.014-0.093 microg g(-1) Hg dry wt. There were no significant differences in mercury concentrations among the three lakes (F = 0.07; p = 0.794). From this baseline data of contaminants in quagga mussels from the lower Colorado River, this species may be used to biomonitor lake health.
最近，Dressenid 物种——斑马贻贝（Dreissena bugensis）入侵了米德湖、莫哈维湖和哈瓦苏湖，这引发了人们对于它们改变污染物循环能力的质疑。研究人员从这三个湖中 25 个不同的地点采集了贻贝样本。整体平均值为 0.036 +/- 0.016 microg g(-1) 汞干重。三个湖的汞含量范围从 0.014-0.093 microg g(-1) 汞干重。这三个湖中汞的浓度没有显著差异（F = 0.07；p = 0.794）。基于科罗拉多河下游斑马贻贝中的污染物基线数据，这种贻贝可能被用于监测湖泊健康。
