Pollutions of Nutrient Salts and Heavy Metals of Groundwater in Xihe River Basin in Shenyang
Abstract:
In order to evaluate the groundwater quality in the Xihe River Basin, the concentrations of fluoride (F-), chloride (Cl-), nitrite (NO2-), nitrate (NO3-), mercury (Hg), cadmium (Cd), zinc (Zn), lead (Pb) and barium (Ba) of the groundwater were investigated in the three sections, Section I, II and III for the upstream, midstream and down stream, respectively. A method of Nemero composite index was used to evaluate the groundwater quality. The concentrations of nutrient salts of groundwater in the Xihe River basin decreased from the upstream to the midstream and downstream. The values of heavy metals were higher in the midstream than in the upstream and downstream. The groundwater had obvious nutrient-salt pollutions in the upstream and midstream. According to the Nemero composite index the F-values of groundwater were 9.5, 5.7 and 0.3 in the up-, mid-and downstream, respectively, indicated that the groundwater in the midstream and the upstream of Xihe River basin was polluted and extremely polluted, respectively.
