艾伯塔省的研究发现,老煤矿污染水,尽管进行了清理工作,但水生生物仍受到损害。 Alberta study finds old coal mines polluting water, harming aquatic life despite cleanup efforts.

艾伯塔省政府科学家最近进行的一项研究表明,该省旧煤矿正在造成水污染,并由于等高浓度污染物而危及水生生命。 A recent study by Alberta government scientists reveals that the province's old coal mines are causing water pollution and endangering aquatic life due to high levels of contaminants like selenium. 尽管作出了开垦努力,但三枚地雷下游河流的这些污染物的浓度仍不安全。 Despite reclamation efforts, rivers downstream from three mines still show unsafe concentrations of these pollutants. 作者认为,现行法规和做法不完善,要求采取更强有力的措施保护水质和水生生态系统,强调对艾伯塔省未来煤炭项目的关切。 The authors argue that current regulations and practices are inadequate and call for stronger measures to protect water quality and aquatic ecosystems, highlighting concerns for future coal projects in Alberta.
