- Abstract:
- To understand the contents of lead and distribution of the promising new planning and old vegetable plantation in Beibei District of Chongqing, and provide basic data for vegetable production, in August 2010, we made an analysis of the lead contents of topsoil in vegetable plantation of Beibei District through field sampling and test in lab, and adopted single pollution index method to evaluate the pollution degree. Results show that: the average content of topsoil in vegetable plantation in Beibei is 43.92 mg/kg, the maximum value is 4.71 times of the lowest. Through calculating pollution index of Beibei vegetable plantation, it shows that vegetable plantation of Beibei District in that lead level can completely satisfy non-pollution vegetable production, and the basic satisfy green vegetable production. The main natural factors which can impact the lead content of study area are the types of soil, and the pH value, clay and organic matter content in basic properties of the soil, the artificial factor is the distance from the highway.
