| Abstract: | The use of reclaimed water for environment and recreation is one of the important ways of water reuse.A key problem for this way is how to assess the risk of the reclaimed water.According to the major pollutants in reclaimed water and their possible exposure ways,the key assessment indicators of reclaimed water for recreational and environmental use were discussed with considering the related criteria of domestic and foreign countries.The significance and applicability of human health risk indicators(including chemical indicators and microbiological indicators)and ecological risk indicators(including integrated toxicity indicators and eutrophication indicators)were analyzed.The scientific indicators and quantitative assessment methods for reclaimed water used in environmental and recreational fields should be studied further in future. |
