Development of a risk rank model for environmental risk assessment of abrupt water pollution accidents
In recent years, abrupt water pollution accidents have broken out frequently in watersheds and caused huge environmental and economic losses. These accidents have become one of the most serious environmental problems in China. Abrupt accidents in watersheds involve large scale, multiple sources, multiple stressors and complex risk spread relationships. An appropriate environmental risk assessment method that can solve these problems is needed to protect water quality and the safety of people and property. In this paper, we have adopted a risk rank method in ecological risk assessment and modify it to assess the risk of abrupt water pollution accidents in watersheds, and take a reach of Laoguan River in Xichuan County, Nanyang city as an example. After identifying risk factors and their relationships, the risk rank model is established accordingly, and then risk values are calculated. Finally, the assessment result is displayed and specific risk management decisions are provided.
