The Study Of Plant In Local Smelting Heavy Metal Pollution Area, Guizhou Province

The soil heavy metals pollution is make local pollution of the environment of important factor, this text take the lead zinc ore native method smelt zinc location in a region of the expensive state province of Hezhang as the research object, study the local native method smelt zinc result in of the soil pollution and growths are on that soil of the pollution circumstance of the plant . Different from growth plant the quilt in the nature of the mineral area, soil is circumstance by the heavy metals pollution to be withdrawn the lead, zinc, cd within the method(total three step) research soil continuously by the simplification that the Maiz put forward of appearance of the plant main research farm crop of that region.Have two aspects to the research of the plant: The farm crop and natures plant the quilt. The farm crop mainly studied the main farm crop corn, potato, soybean , etc. of the region, pass as to it's three kinds of heavy metals chemical elements of the measurement assurance lead, zinc, cd of the content of the heavy metals in the body chemical element are in each farming object of distribute the circumstance and fruits in the content of the heavy metals .Root, caulis leaf, fruit three parts of content of the farm crop can see an above-mentioned three kinds of heavy metals chemical elements in the farming object of migration circumstance and each part of farm crop be degree by the heavy metals pollution. Combine the farming object inside the different from soil in appearance of the heavy metals content of each part of heavy metals content pass to their the related analysis can get a heavy metals at each appearance in the soil to farm crop of the influence and the contribution degree.1, the relation between corn and heavy metalsThe appearance of Cacl2 and content of Zn in the corns of the soil didn't related relation that display to show the relation , the content of Zn...
