In this study, some metals (aluminium, chromium, copper, iron, manganese, lead, zinc and vanadium) and metalloid (silicon) were determined in water, sediment and some tissues of fish Cyprinus carpio from Mogan Lake. Fish samples were caught in March 2007. As a result of the examination of metals in the water aluminium has the lowest and silicon has the highest concentration. In sediment samples...

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

Background & Aims of the Study: Leachate production is a major problem for solid waste landfills and causes important threat to health public and environment. One of the typical properties of heavy metals is that they cannot easily decompose in the environment. The aim of this study was to measure of heavy metals concentrations in old-age leachate from Qazvin landfill site, Ira...

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...

zinc (zn) and copper (cu) are essential elements and increased plant growth in low concentrations. while high concentrations of these elements as a limiting factor, can cause adverse symptoms on the plants. in the present study, the uptake of micronutrient and macronutrient by pennyroyal were studied in a zn and cu deficiency and toxicity in soil. three levels of copper (0, 5 and 25 mg/kg) and ...

levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...
