Cadmium uptake by plants.
Food chain contamination by cadmium (Cd) is the most important pathway of Cd exposure to the general population, excluding smokers. Factors affecting transfer of Cd from soil and air to plants are reviewed. The direct deposition of airborne Cd in the plants has only a marginal influence on the crop Cd concentrations in rural areas with low atmospheric Cd deposition, i.e. < 2 g Cd ha(-1) y(-1). ...
متن کاملCharacteristics of cadmium uptake and accumulation by two contrasting ecotypes of Sedum alfredii Hance.
The mined ecotype of Sedum alfredii Hance has been identified to be a zinc (Zn) hyperaccumulator native to China. In the present article, the characteristics of cadmium (Cd) uptake and accumulation were compared with hydroponic experiments between the mined and the nonmined ecotypes of Sedum alfredii Hance. The results indicate that the plants of the mined ecotype (ME) have higher tolerance of ...
متن کاملEffects of full and limited irrigation and contaminated soil on cadmium uptake by corn
Using plants for the remediation of soils contaminated with heavy metals is an economical, cheap, and effective strategy. The goal of this research was to study the effect of sewage sludge and drought stress on the remediation of cadmium in soil, root uptake by corn plant. This study was carried out on corn in factorial design experiment based on completely randomized design with three replicat...
متن کاملsimultaneous uptake and accumulation of sodium and cadmium or lead by three halophyte plants in two calcareous soils
abstract nowadays, environmental pollution by heavy metals is one of the most serious threats of the world which needs effective remediation actions. the aim of this study was to investigate the potential use of atriplex [atriplex verucifera], salicornia [salicornia europaea] and chenopodium album in simultaneous uptake and accumulation of na and cd or pb in two calcareous soils with different ...
متن کاملCadmium, Nickel and Vanadium Accumulation by Three Strains of Marine Bacteria
Three marine bacteria, Pseudomonas putida PTCC 1664, Bacillus cereus PTTC 1665 and Pseudomonas pseudoalkaligenes PTCC 1666 isolated from the East Anzali wetland sediments of the Caspian Sea, were resistant to heavy metals of Cadmium (Cd), Nickel (Ni) and Vanadium (V). Pseudomonas pseudoalkaligenes PTCC 1666 was found to be resistant to all 3 metals Ni, Cd, V. Heavy metal uptake was determined ...
