Cadmium (Cd) and its rate in soil have received lots of attention because it is easily taken up by plant root, making it 20 times more toxic in comparison with other heavy metals. Knowledge about the factors affecting Cd availability and conversion of its chemical forms is, therefore, important. Sequential extraction has been used as a suitable method for identification of chemical forms and th...
This research was conducted to study the effect of natural and polyacrylamide-modified montmorillonite on the sorption of Cd from aqueous solutions. The sorption of Cd on the sorbents was studied as a function of pH (Cd concentration: 10 mg L-1) in the range of 4-8.5, and as a function of metal concentration (Cd concentration in the range of 1-10 mgL-1) using a 24h batch equilibration. Experime...
Heavy metals including cadmium (Cd) and lead (Pb) are entering agricultural soils from different routes and mainly due to human activities. Accumulated Cd and Pb in the soil would eventually enter the human and animal food chains and pose threat to their health. Therefore, evaluating heavy metal accumulation is necessary to prevent soil and environmental pollutions and should be considered by r...
objective: celiac disease (cd) is developed via autoimmune reactions against gluten which is mainly found in grains. although hla dqb1 locus is the most important genetic susceptibility to cd, some other variants such as a49g and g1359t of ctla4 and cd14 genes respectively have been proposed as cd predisposing genetic factors in many various studies. we aimed to assess possible roles of a49g an...
A greenhouse experiment was conducted in 2013 in Research Lab of Karaj Islamic Azad University to determine the yield and activity of chemical markers as the response to different concentrations of Cadmium (Cd) (0, 5, 10 and 20 mg of Cd/kg of soil) in wheat cultivars (Karaj 1 and Karaj 2). Treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. The respon...
a greenhouse experiment was conducted to investigate the effects of mycorrhial fungus (glomus mosseae) on cadmium (cd) toxicity in pepper (capsicum annuum l. cv. zhongjiao 105) plants. half of plants were inoculated with arbuscular mycorrhizal fungi (amf). cd was supplied in the form of cadmium chloride at 0.0, 0.1 and 0.5 mm through irrigation water in the soil. mycorrhizal colonization was hi...
