Surface water contains a large number of pollutants, particularly human pathogens, organic toxicants and heavy metals. Due to the toxic nature of heavy metals towards marine organisms, its removal from the environment has been a growing issue. The biosorption of heavy metal ions from surface water using fish scales has emerged as an environmentally friendly technique. This study assessed the de...

Iron (Fe) and copper (Cu) metabolism are closely intertwined, and a deficiency of Cu may lead to a secondary Fe deficiency. The impact of a severe Cu deficiency on proteins involved in Fe metabolism in the bovine has not been studied. Therefore, a 493 day study was conducted to determine the effect of a severe long-term Cu deficiency on Fe metabolism in beef cattle. Twenty-one Angus calves were...

in this research, the spatial distribution of fe, cu, zn and mn on agricultural lands of golestan province were evaluated using different interpolation methods such as, kriging, inverse distance weighted, local polynomial, inverse multiquadric and radial basis function. thus, 505 soil samples were provided from fields during 2008 and micronutrients rates were measured for each sample. the perfo...

mapping based on total concentrations of micronutrients may be useful in fertility management including fertilizer and/or wastewater application. the aims of this work were to (1) investigate the spatial distribution of total concentrations of copper (cu), zinc (zn), manganese (mn) and iron (fe); (2) to select the suitable spatial estimator; and (3) to understand the effect of wastewater irriga...

To evaluate the effects of chelated Zn/Cu/Mn on redox status, immune responses and hoof health in lactating Holstein cows, 48 head in early lactation were divided into healthy or lame groups according to their gait score. Cows were fed the same amount of Zn/Cu/Mn as sulfate salts or in chelated forms for 180 days, and foot-and-mouth disease (FMD) vaccine was injected at day 90. The results show...

metals concentrations in lumbricus terrestris and soil samples from the dumpsites located in zaria metropolis, nigeria were measured spectrophotometrically. mean metal content in dumpsite soils were: 25.95 - 75.17, 8.33 - 382.94, 124.84 - 206.96, 34.24 - 666.67 and 111.11 - 488.10mg/kg for cd, cu, mn, pb and zn respectively. while the concentration ranges recorded in l. terrestris samples were;...

in order to evaluate the effect of foliar application of micro nutrients on physiological growth indices and total dry matter yield of forage corn. field experiment was conducted in 2006 at bersian village isfahan. a randomized complete block design with four replications was used. plant treated with 8 foliar application treatments (fe, zn, cu, mn, fe + mn, cu + zn, fe + mn + cu + zn and contro...

BACKGROUND Sweet fennel (Foeniculum vulgare Mill.) is one of the precious spices. Almost all parts of fennel plant are edible. The herb is used as carminative, digestive, diuretic, cosmetic and medicine. METHODS A 0.5 g of the oven dried fennel fruit and soil samples were digested by wet-digestion method. The levels of selected elements (Ca, Mg, Fe, Mn, Cu, Cr, Co, Zn, Ni, Cd and Pb) were det...
