Abstract:
The elevation and slope of tea garden were selected as the research objects of the transfer law of total arsenic content in soil. A regression model was established by analysing the correlation between the information obtained from the tea garden and the measured data in laboratory. The results showed that the total arsenic content in tea garden soil was significantly correlated with the elevation and slope of tea garden. With the decrease of elevation and the decrease of slope, the total arsenic content in tea garden soil increased gradually, and the trend of total arsenic content in tea garden soil increased to a certain elevation and slope, which exceeded the standard of screening value(40mg/kg) in risk management standard.
