The geochemistry and mineralogy of samples collected along depth profiles from an As-rich tailing deposit with abundant calcite was studied to determine the processes that influence the mobility of Fe, Zn, Cu, Ni, Cd, As, Sb, Cr and Tl. In spite of their near neutral pH, almost all of them are acid potential generators. Total concentrations decreased as: Fe > As > Zn > Pb > Cu > Sb > Cd > Cr > ...

In order to determine effect salicylic acid and Zn on characteristics of pistachio nut (Pistacia vera L. cv. Owhadi), the experiment was carried out as factorial in the framework of CRD design with three replications. The results showed that salicylic acid and Zn increased nut fresh weight and decreased blank nut percentage. The application of salicylic acid decreased splitting percentage and k...

In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...

Heavy metal pollution has become an increasingly recognized threat to the aquatic environment. In response to heavy metal stresses, various terrestrial plants produce the hormone nitric oxide (NO), but minimal information is available about the role of NO in aquatic macrophytes under high zinc (Zn) stress. In this study, we measured physiochemical parameters in the leaves of Hydrilla verticilla...

Abstract The objective of this work was to evaluate the use bentonite as an additive in composting wastewater sludge from poultry agroindustry regarding nitrogen conservation, carbon degradation, and nutrient content increase. experimental design completely randomized with five treatments at 0, 0.5, 1.0, 3.0, 6.0%, three replicates. organic compost used consisted pine sawdust treatment plant. D...

Concerns over the possible increase in phytoavailability of biosolids-applied trace metals to plants have been raised based on the assumption that decomposition of applied organic matter would increase phytoavailability. The objectives of this study were to assess the effect of time on chemical extractability and concentration of Cd, Cu, Ni, and Zn in plants on plots established by a single app...

To asses the micronutrient status of soils under legume crop in arid region of Western Rajasthan a study was conducted. A total of 652 soil samples (445 samples of rhizosphere and 207 samples of non-rhizosphere) from farmer’s field were collected and analyzed for DTPA-extractable micronutrient status and soil properties. Content of micronutrient was in order of Mn> Fe> Cu> Zn. The DTPAMn, Fe, C...

Microwave digestion-inductively coupled plasma astigmatism (ICP-AES) was used to analyze the contents of mineral elements (including K, P, Mg, Ca, Na, Fe, Cu, Mn, B, Zn, Se, Li) in 54 Olecranon Peaches collected from Shangping town, Lianping County. The obtained data analyzed by Correlation analysis (CA), combined with fruit reducing sugar (RS%), sugar-acid ratio (S/A) and sensory scores. resul...
