| 【Objective】 The study was to investigate the content characteristics and correlations of pH, Cd
and Pb in Cd and Pb contaminated soils in Anhui Province.【Methods】According to the determination method
of soil heavy metal elements, the contents of pH, total Cd, available Cd, total Pb and available Pb in the Cd and Pb
contaminated alluvial soil, red soil, yellow cinnamon soil and paddy soil in Anhui Province were analyzed.【Results】
The results showed that there was a significant positive correlation between the available Pb and the total Pb in Cd and Pb
contaminated alluvial soil, red soil and paddy soil in Anhui Province, with significant levels of 0.685, 0.348 and 0.730,
respectively. There was a significant positive correlation between available Cd and total Cd in red soil and paddy soil, with
significant levels of 0.365 and 0.899, respectively. There was a significant positive correlation between pH and available
Pb in alluvial soil, with a significant level of 0.555. There was also a significant positive correlation between available Cd
and total Pb in red soil, with a significant level of 0.352.【Conclusion】Among the four types of tested soil, the contents
of available Cd and available Pb of red soil were mainly affected by total Cd and total Pb. The available Cd and available
Pb in paddy soil were mainly determined by their total amount. The content of available Pb in alluvial soil was greatly
affected by the total Pb and pH. |
