Emerging and priority oxyanionic contaminants such as antimony, chromium, vanadium and tungsten present a significant environmental hazard. They are often associated with mining, and numerous contaminated sites have been identified within Australia. In order to manage these contaminants appropriately, there needs to be suitable methods to analyse them. Passive sampling technology will be developed that will allow the measurement of these contaminants and their speciation in water, and sediment and soil pore waters. This project will use these new samplers to investigate the geochemical mechanisms of mobilisation of these contaminants in laboratory mesocosm experiments, as well as at selected contaminated field sites within Australia.

新出现的和优先的氧阴离子污染物，如锑、铬、钒和钨，对环境具有重大危害。它们往往与采矿有关，澳大利亚境内已查明许多受污染的地点。为了适当管理这些污染物，需要有合适的方法来分析它们。将开发被动取样技术，以便测量这些污染物及其在水、沉积物和土壤孔隙沃茨中的形态。该项目将使用这些新的采样器来调查这些污染物在实验室围隔实验中以及在澳大利亚境内选定的受污染现场动员的地球化学机制。
