The present investigation was aimed to study the distribution, enrichment and accumulation of heavy metals in soil and Vigna mungo (Black gram, var. Pant U-30) after irrigation with distillery wastewater. A field experiment was conducted in the experimental garden of Gurukula Kangri University, Haridwar during the year 2012 and 2013. Treatments of distillery wastewater viz. 20%, 40%, 60%, 80% a...

Natural dark mink kit were fed a diet supplemented with 0, 25, 50, 100 or 200 ppm Cu from CuSO4 . 5H2O for 153 or 357 d. The shorter term Cu supplementation had no significant beneficial or adverse effects on mink body weight gains or hemoglobin or hematocrit concentrations, although plasma Cu concentrations were slightly elevated in the mink fed added Cu. Liver Cu concentrations were significa...

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 order to improve the shoot proliferation rate of ‘Dwarf Cavendish’ banana shoot tip cultures, polyethylene glycol (PEG6000) was employed at concentrations of 2, 4, and 6% (w/v). The medium without PEG was considered as negative control. An increasing of shoot proliferation was achieved in MS medium containing 2% PEG. Furthermore, application of 2% PEG significantly increased the shoot dry we...

concentrations of major nutritional and trace elements (ca, p, mg, na, k, fe, zn, cu, mn, se,co, cr, ni, sr, ba) and toxic heavy metals (cd, pb) were analyzed in the meat of limousin, red angus andsalers bulls. elements were determined using inductively coupled plasma emission atomic spectrometry. theconducted research showed that the meat of compared breeds differed in the concentrations of cu...

An attempt was made to unravel further the mechanism by which high dietary concentrations of ascorbic acid influence copper metabolism. The addition of ascorbic acid to the diet of rats caused about a twofold increase in plasma ascorbate concentrations and reduced group mean plasma and tissue concentrations of Cu. The effect of 10 g ascorbic acid/kg diet was greater than that of 1 g/kg. Ascorbi...

In this study, the effects of non-hazardous levels of heavy metal (Zn, Cu, Cr and Cd)-enriched organic waste on biomass partitioning and heavy metal accumulation in plant organs in July and October were determined for two poplar clones (Populus deltoides × maximowiczii—clone Eridano and P. × euramericana—clone I-214) commonly used in Italian poplar plantations. Soil amended with the industrial ...

to evaluate the effects of various concentration of carbon dioxide and salinity stress on morphophysiological characteristics of amaranthus tricolor l. an experiment was conducted in greenhouse conditions in faculity of agriculture ferdowsi university of mashhad. the experiment was split plot based on completely randomized design with three levels of co2 (380, 700, 1050 µl/l) and three concentr...

The absorption characteristics of Cd(2+) by 10- to 12-day-old soybean plants (Glycine max cv Williams) were investigated with respect to influence of Cd concentration on adsorption to root surfaces, root absorption, transport kinetics and interaction with the nutrient cations Cu(2+), Fe(2+), Mn(2+), and Zn(2+). The fraction of nonexchangeable Cd bound to roots remained relatively constant at 20...
