| Abstract: | The article gives an account of the natural content of some elements, 666 and DDT, of soil and plant in Yi Zheng Chemical fibre area, and gives a current assessment of soil. The concentration of elements in soil is dependent on their parent meterials and types of soil. The content of some elements in soil is in relation to the physicoehemical composition of soil. The content of some elements in the surface soil derived from self area was higher than that in the substratum. The content of some elements in soil and plant was smaller. It can be regarded natural content of some elements, 666 and DDT in soil and plant of most part of the area as background values. The chlorinated hydrocarbon contents of soil and plant were lower than at home and abroad. The order of contents in plant were as follows: natural plant>fruit tree>green vegetables>wheat seedling; leaf>leafstalk. The current assessment of soil in most parts of the area is that it is a clean and passable region. |
