Samples of zebra mussels, Dreissena polymorpha, from populations infesting two power generating stations on Lake Erie were subjected to tests assessing the potential for leaching of metals and other (inorganic and organic) contaminants from mussel waste destined for disposal in conventional landfills. These tests revealed that mussels collected from Ontario Hydro's Nanticoke Thermal Generating Station and Niagara Mohawk Power Corporation's Dunkirk Steam Station did not release hazardous materials in excess of limits set forth in Canadian and U.S. regulations, respectively. A variety of metals and inorganic materials leached from Nanticoke mussels at levels significantly lower than the registration limits for those analytes. Detectable levels of chloroform (0.080 mg/liter) and barium (3.3 mg/liter) leached from Dunkirk mussels at > 30-fold lower levels than U.S. regulatory action limits for those materials. Whole body analyses revealed a lack of detectable levels of herbicides and pesticides in either population with a variety of metals and inorganic constituents in all samples from both populations. The physiological condition of Dunkirk mussels appeared to be consistent with that of other Lake Erie populations based on percentage water and total fat content of soft tissues.
从伊利湖两座发电站采集的斑马贻贝（Dreissena polymorpha）样本，接受了相关测试，以评估来自贻贝废弃物的金属及其他（无机和有机）污染物在常规垃圾填埋场处置时的潜在沥出可能性。这些测试表明，从安大略水电公司的南蒂科克热电厂和尼亚加拉莫霍克电力公司的敦刻尔克蒸汽站采集的贻贝，分别释放的有害物质未超过加拿大和美国法规规定的限值。从南蒂科克贻贝中沥出的多种金属和无机物质的含量，显著低于这些分析物的登记限值。从敦刻尔克贻贝中沥出的可检测水平的氯仿（0.080毫克/升）和钡（3.3毫克/升），比美国对这些物质的监管行动限值低30倍以上。全身分析显示，两个种群的贻贝中均未检测到除草剂和杀虫剂，且两个种群的所有样本中都含有多种金属和无机成分。基于软组织的含水量和总脂肪含量，敦刻尔克贻贝的生理状况似乎与伊利湖其他种群一致。
