Analysis of hexavalent chromium uptake by plants in polluted soils
Concentration levels of hexavalent chromium in contaminated soil and in Zea mays plant parts were determined and Cr(VI) bioaccumulation and bioconcentration capacity of this plant were discussed. Zea mays seeds were sown in 40 mg Cr(VI)/kg dw polluted soil. After harvesting it was observed that hexavalent chromium concentrations in plant organs decreased in the following order: roots > stems > ...
متن کاملAccumulation of Lead and Arsenic by Lettuce Grown on Lead-arsenate Contaminated Orchard Soils
s: Lead-arsenate was used to control codling moth (Cydia pomonella) in apple (Malus sylvestris Mill) orchards from the 1900’s to the1960’s. Lead and arsenic are generally immobile and remain in the surface soil. Some orchard lands are being used for vegetable crop production. There are concerns of lead and arsenic accumulation in vegetables crops grown in these soils. Objectives were to 1) dete...
متن کاملPhytoremediation of arsenic contaminated paddy soils with Pteris vittata markedly reduces arsenic uptake by rice.
Arsenic (As) accumulation in food crops such as rice is of major concern. To investigate whether phytoremediation can reduce As uptake by rice, the As hyperaccumulator Pteris vittata was grown in five contaminated paddy soils in a pot experiment. Over a 9-month period P. vittata removed 3.5-11.4% of the total soil As, and decreased phosphate-extractable As and soil pore water As by 11-38% and 1...
متن کاملArsenic and Lead Uptake by Vegetable Crops Grown on an Old Orchard Site Amended with Compost.
The potential for lead (Pb) and arsenic (As) transfer into vegetables was studied on old orchard land contaminated by lead arsenate pesticides. Root (carrot), leafy (lettuce), and vegetable fruits (green bean, tomato) were grown on seven "miniplots" with soil concentrations ranging from near background to ≈ 800 and ≈ 200 mg kg-1 of total Pb and As, respectively. Each miniplot was divided into s...
متن کاملCalcium, Magnesium, and Potassium Uptake by Crested Wheatgrass Grown on Calcareous Soils
Forage intake with potassium/(calcium + magnesium) [K/(Mg + Ca)] values in excess of 2.2 are associated with grass tetany and Mg deficiencies in ruminants. This study was conducted to determine the degree to which forage K and Mg concentrations and K/(Ca + Mg) ratios could be predicted from soil bicarbonate (HCO3) extractable phosphate-phosphorus (PO4-P), and saturation extract Ca, Mg, K, sodiu...
