Explain the Cause of pH Value Decreasing These Years in Precipitation of Shanghai City with Stepwise Linear Multi-variation Regression Mode

Huang Yinzhi1,Zhang Mingxu2(1.Donghua University,Shanghai 201620,China;2.Shanghai Environmental Monitoring Center,Shanghai 200030,China)  
On analysis of Characteristics of Chemical Composition of precipitation from year 2002 to 2007 in Shanghai city,it shows the pH value is decreasing dramatically these years,and both of the ratios of SO2-4/NO3-and Ca2+/NH+4 have decreased.Based on the concentration of the major ions in the precipitation of Shanghai city,a stepwise linear multi-variation regression model to predict hydrogen ion is established.The influence of the variation of the concentration of the main ions on the concentration of the H+ is analyzed based on the model established.Some conclusions were drawn from the modal:the concentration of H+ increases with the increasing of the concentration of SO2-4 or NO-3,while decreases with the increasing of the concentration of Ca2+ and NH+4.The influences of the 4 main ion to the concentration of H+ in the order from strong to weak is NO-3SO2-4Ca2+NH+4.Combine with the conclusion of analysis of characteristics of chemical composition of precipitation,it shows that the variation of the concentration of the major ions results in the dramatic decreasing of pH.
