摘要
In this study,the environmental impacts of six commercial chloride-based de-icer products,including Rock Salt and Salt Brine,were evaluated.The nutrients,oxygen demand,heavy metal concentration,corrosion and toxicity of all six de-icers were analysed.With an assumed 500-fold dilution,the test results were compared to the public water-quality criteria.The results show that the selected chemical de-icers have little chance of severely damaging the environment and ecosystem under a normal dilution scenario.However,attention needs to be paid to small water bodies and sensitive receiving water.
