Title: Heavy Metal Pb and Cd Distribution in Winter-wheat with Reclaimed Water Irrigation
Abstract: The effect of reclaimed water irrigation on crops metal accumulation is a crucial issue for sewage water safely utilization on agriculture.The research studied heavy metal Pb and Cd content and distribution in soil and winter wheat under reclaimed water irrigation by using pot planting trails.The results showed that there was no significant difference in soil Pb,Cd content with reclaimed water irrigation compared with fresh water control treatment.Meanwhile,mixed and alternative irrigation of reclaimed water and fresh water could little reduce Cd and Pb soil content compare with purely using reclaimed water.Cd content order in different organ of winter wheat was root leaf stem grain,and it had somewhat increase compared with fresh water treatment.The Pb content order in different organ of winter wheat was leaf root stem grain,the higher Pb content in leaves was likely related with air pollution of experiment trail site.Both Pb and Cd content in different organ had no significant difference between reclaimed water irrigation and fresh water treatment.The Pb and Cd content in grains were lower than National Restriction of Pb and Cd content for food consumption,but Cd content was little higher with reclaimed water irrigation than fresh water which should be noticed in field practice.
