施加水铁矿对不同蔬菜富集砷的影响
Ferrihydrite Application Affects Arsenic Accumulation in Different Vegetables
摘要
Abstract
This study aimed to investigate the effect of ferrihydrite on arsenic accumulation in four vegetable species:Brassica campestris L.,Daucus carota var.sativa Hoffm.,Apium graveolens L.,and Capsicum annuum.The synthesized ferrihydrite was applied to arsenic contaminated soil for pot experiments.The results showed that the percentage of available arsenic in soils decreased with the increase in ferrihydrite dose.The application of ferrihydrite resulted in decreases of 72.41%,63.72%,and 92.74%in arsenic content in the edible parts of D.carota var.sativa,A.graveolens,and C.annuum,respectively.Moreover,the changes in As(Ⅲ)and As(Ⅴ)content in these three vegetables were consistent with that in arsenic content.The ferrihydrite application did not significantly affect the arsenic content in B.campestris.The optimal dose of ferrihydrite applied to D.carota var.sativa,A.graveolens,and C.annuum were 0.5%,0.5%,and 1%,respectively.Therefore,ferrihydrite could be applied to limit the accumulation of arsenic in edible parts of vegetables in arsenic contaminated areas.关键词
