In order to determine the effects of cadmium on growth, physiological parameters, and nutritional elements’ concentration in tomato organs in a soilless system, an experiment was conducted in greenhouse of Isfahan Agricultural and Natural Resources Research Center in 2008 with a complete randomized block design with two treatments and 6 replications. The treatments were nutritional solutions of...
Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...
Zinc is one of the essential elements in biological system. The role of this element in many enzymes has been proved. Zinc has an antagonistic effect on the toxic elements such as cadmium, as both binds to a carrier protein called metalothionein . Zinc can be found in atmosphere of different industrial environment. Due to its importance, it's concentration in the serum of 399 Male workers of sa...
In a pot experiment, the effect of soybeans, mung beans and beans on the corn and sunflowers in a cadmium contaminated soil was studied in a completely randomized design with three replications. The treatments consisted of intercropping of corn and mung bean corn and beans, corn and soybean, sunflower and mung bean, sunflower and beans, sunflower and soybean monoculture of corn, and monoculture...
the effect of different levels of zinc and copper organic supplements on performance, plasma copper plus zinc status, serum alkaline phosphatase (alp), ceruloplasmin (cp) activity as well as vitamin ¬a concentration was studied in 25 mehraban male lambs each of 5-6 months of age and 30/64±3/47kg of live weight. the following five dietary treatments were used: 1) control (base diet with no addit...
Cadmium is classified as a human carcinogen, and its disturbance in zinc homeostasis has been well established. However, its extent as well as molecular mechanisms involved in cadmium carcinogenesis has yet to be fully clarified. To this end, we used the zinc specific probe Zinquin to visualize and to quantitatively evaluate changes in the concentration of labile zinc, in an in vitro model of h...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Abstract The scientific report assessed the impact of Nalla Lai wastewater on groundwater quality Rawalpindi city, Pakistan. A total 19 and 49 samples were collected during September October 2016 have been analyzed in laboratory to detect different water parameters. results revealed that BOD (biological oxygen demand), COD (chemical iron, cadmium values many beyond recommended value National En...
cadmium is a highly toxic heavy metal and one of the most important environmental pollutants. cadmium has a particular interest among the heavy elements due to the high mobility, solubility, and toxicity for human, plants, and other organisms. in order to study cadmium toxic effect on green pepper, a completely randomized design was performed with three levels of cadmium (0, 0.25, and 0.5 mm as...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
