| Abstract: | In order to find the Cd pollution and impact factors on the migration in soil-rice system in Yangtze River Delta Region,66 groups of soil,rice shoot and rice grain from typical area were sampled;contents of heavy metals and major elements,soil pH,soil total organic carbon of those samples were measured;Cd pollution in soil and rice grain were evaluated by the means of relevance analysis,and the distribution of Cd were shown;impacts of soil pH and organic carbon,and other metal elements on Cd accumulation in... |
