In situ bioremediation of high sulphide environments

加拿大的水供应正受到威胁，因为用于支持野生动物和家畜（如牛）的清洁无毒水的数量越来越少。在加拿大的一些地区，高浓度的硫化合物是造成对许多物种有毒的环境的原因。这些包括受地雷影响的环境，如矿坑湖和尾矿池。在其他地区，如不列颠哥伦比亚省的Okanagan，由于天然高硫酸盐浓度，牛的饮用水短缺。此外，一些硫化物含量高的分层湖泊的溶解度很低，鱼类无法居住。因此，我们的工作是针对研究生物和其他环境因素，调节这些系统中的硫循环，以期开发原位生物修复策略，以改善水质。

Canada's water supply is under threat due to diminishing quantities of clean, non-toxic water for supporting wildlife and also for domestic livestock such as cattle. In some parts of Canada, high concentrations of sulphur compounds are responsible for creating environments toxic to many species. These include mine affected environments such as mine pit lakes and tailing ponds. In other areas, such as the Okanagan, BC, there is a shortage of drinking water for cattle due to naturally high sulphate concentrations. In addition, some stratified lakes high in sulphide have very low diversities and are uninhabitable by fish. Thus, our work is directed at studying biological and other environmental factors that regulate sulphur cycling in these systems with a view to developing in situ bioremediation strategies for improving water quality.
