Effects Of Weathered Coal On Heavy Metal Content In Cabbage And Form In Soil By Combined Pollution Between Copper Zinc Lead And Cadmium

Currently,soil heavy metal pollution has caused widespread concern,but in the current study,more research single heavy metal pollution, or the pollution of heavy metals is a composite of the two studies,while the two heavy metal elements Study the above combined pollution is relatively small.In fact, when the heavy metal pollution problems occur in the soil environment,usually combined pollution of heavy metals.Research on combined pollution and contamination of soil chemical ecology is a fundamental problem,and has important practical significance heavy metal pollution prevention and control. But the study of complex pollution is a complex phenomenon currently found only a little,but also a lack of precise characterization of this compound can be an indicator of pollution,research in this area needs to be further explored.Research on this subject by studying the ultrasonic treatment weathered coal on heavy metals contamination of soil heavy and morphology,is designed to ease the weathered coal toxic heavy metals contamination provide a theoretical basis.The main experimental results are as follows:Add 40,60,80g/kg untreated weathered coal and ultrasonic treated weathered coal,may reduce soil in weak acid extractable,reducible,oxidizable of Cu,Zn,Pb,Cd content,reducing soil of Cu,Zn,Pb,Cdmobility,thereby reducing soil Cu,Zn,Pb,plant effectiveness and toxicity,soil Cu,Zn,Pb,Cd content increases,the plant for Cu, reduce the absorption of Zn,Pb,Cd’s.Under the same conditions the amount of weathered coal, weathered coal ultrasonic treatment compared with untreated weathered coal to a greater degree of reduction in weak acid soil extractable, reducible, oxidizable of Cu,Zn,Pb,Cd’s,improve residual Cu,Zn,Pb,Cd’s,reducing Cu,Zn,Pb,Cd mobility,thereby reducing soil Cu,Zn,Pb,Cd plant effectiveness and toxicity,reducing the plant to Cu,Zn,Pb,Cd absorption.
