Background & Aims of the Study: Tea is one of the most important beverages that consumes in several parts of the world including Iran. Tea plant can be contaminated during manufacturing processes and growth period by pollutants such as heavy metals. In this study, the concentration of some heavy metals in different brands of both Iranian and imported black tea to Iran was inves...

since they may expose to inorganic pollutants, drinking waters should be investigated andmonitored in industrialized regions. in this study, drinking water samples taken from eight different locationsin heavily industrialized region of turkey, namely marmara region, were analyzed to determine heavy metaland harmful trace element (fe, co, cd, hg, pb, zn, sb, cu, ba, mo, cr, mn and v) concentrati...

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

Cadmium is a potentially toxic heavy metal that enters food chain from the soil through various anthropogenic sources. Availability of metal ions in contaminated soils can be reduced by the addition of organic amendments. In this study, effect of organic matter -farm yard manure (FYM) amendment on fractionation and availability of Cd to maize was evaluated. A green house experiment was conducte...

introduction: vermicompost is one of the important bio-fertilizer which is the product of the process of composting different organic wastes such as manures and crop residues using different earthworms. vermicomposts, especially those are derived from animal wastes,contain the large amounts of nutrients compaired with the composts prepared from crop residues. vermicomposts contain plant availab...

The foliar diagnosis can be considered as a useful tool to assess the nutritional status of plants. The diagnosis and recommendation integrated system (DRIS) has been developed for this purpose. In this study DRIS norms were determined for wheat plant (Triticum aestivum L.) in the Moghan region, northwest of Iran. A data bank created from nutrients concentrations of flag leaf and yield was use...

Genotoxicity of Cu and Zn was assessed by use of the micronucleus (MN) test on Vicia faba roots. Plants were exposed to various leachates of raw and anaerobically digested pig slurry, with maximum total concentrations of 200microM Cu and 600microM Zn. The results indicated stabilisation of the organic matter during anaerobic digestion of the slurry and bioconversion of some phytotoxic organic c...

the concentration of cu, mn, ni and zn were determined in tomatoes and onions samples using atomic absorption spectrometry. a total of 32 samples each of tomatoes and onions were collected from the exposed and control sites for analysis. the trace metals (cu, mn, ni and zn) concentration in tomatoes wee found to be 6.2406, 6.5521 , 5.7375 and 8.9297 mg/kg-1, respectively. while those of onions ...
