background: this study was carried out to determination of heavy metals (cd, cr, cu, fe, pb, ni and zn) concentration in upstream and downstream of the entry of the wastewater (untreated urban, traditional slaughterhouse waste, leachate from solid wastes has accumulated in river and  run off waters flowing across the city ) to the tembi river. methods: samples were collected for 1 year, before ...

A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...

in order to investigate the effects of applying three and five continuous periods of municipal solid waste (msw) with and without npk chemical fertilizer on the amount of micronutrient uptake by different parts of wheat, a pot experiment was conducted in split plot based on randomized complete block design with four replications in 2009. the main plot was a six-fertilizers level including contr...

Taro (Colocasia esculenta) is an important root crop in the humid tropics and a valuable source of essential mineral nutrients. In the presented study, we compared the mineral compositions of four main parts of taro corm: the upper, marginal, central and lower (basal) parts. The freeze-dried taro samples were analysed for eleven minerals (K, P, Mg, Ca, Zn, Fe, Mn, Cu, Cd, Pb and Cr). The upper ...

A metal-accumulating willow was grown under greenhouse conditions on a Zn/Cd-polluted soil to investigate the effects of sulfur (S(0)) application on metal solubility and plant uptake. Soil porewater samples were analyzed 8 times during 61 days of growth, while DGT-measured metal flux and O2 were chemically mapped at selected times. Sulfur oxidation resulted in soil acidification and related mo...

The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried o...
