The Characterisitic of the Strong Acid Rain in Lin''an
|
Abstract:
In this paper, the data of the strong acid rain from 1985 to 1994 is analysed, and compared with the common acid rain. The results show that the state of the common acid rain happened frequently. The numbers of the strong acid rain are increasing. The frequency of the strong acid rain differed with various seasons, the highest in autumn and the lowest in summer. The amount of the acidic deposition of the strong acid rain is increasing year after year. The annual average of conductivity in the strong acid rain is higher than that in the common acid rain. The negative relationship between conductivity and pH in the strong acid rain is very clear. The rainfall amount of each strong acid rain is usually lower than that of each common acid rain. The positive relationship between rainfall amount and pH is highly notable. The concentration of each ion in the strong acid rain is higher than that in the common acid rain.
