Risk assessment and prediction of heavy metal pollution in sediment of Biliuhe reservoir

Abstract: The Biliuhe reservoir, which is one of the most important water sources in Dalian, is the "source of life" of Dalian. To explore the characteristics of heavy metal pollution in Biliuhe reservoir, the potential ecological risk of these heavy metal elements were evaluated by two methods, i.e. geo-accumulation index and potential ecological risk index, and the risk values of heavy metals in sediment were predicted one year later in the future by grey forecasting model GM (1, 1) and RBF neural network. The compreh… Show more

“…Heavy metals are considered an important indicator of water pollution because, in sediment, they have characteristics such as high abundance and easy accurate detection [18][19][20]. The studies of domestic scholars on the reservoirs of iron and manganese pollution show that: the distribution of iron and manganese changed with seasons as well as reservoir temperature stratification.…”
