this study was conducted in halgheh darreh waste disposal site in karaj in order to determine the concentration of ni and pb in halimocnemis pilifera and in region’s soil. three 50*50 m plots in the direction of the prevailing wind were selected. the first plot was close to the leachate ponds and the next two plots were located at 500 and 1000 m from the first plot, respectively. ten random sam...

concentrations of six heavy metals including cr, mn, ni, pb, v and zn were determined in topsoil (from 47 grid cells), surface water (4 streams) and groundwater (8 wells and 4 qanats) from an agriculturalarea located at south part of the iranian capital, near the tehran oil refinery. concentrations of the elementswere measured using flame and flameless atomic absorption spectrometry. based on t...

the major aim of the present study was to investigate element (fe, ni, pb, v, zn) concentrations in sediment and different tissues of phragmities australis and typha latifolia in hor al-azim wetland southwest iran. sampling of sediments and aquatic plants was carried out during spring and summer 2014. results showed that the mean  concentrations of elements in phragmities australis  in root and...

This study investigated the influence and interactions of geochemical fractions toxic metals in sediments River Ogun Nigeria. Fe, Mn, Zn, Pb, Cr, Co were significantly present across area, while Cu, Ni, Cd negligible. All metals, except found highly above their permissible limits sediments. The bulk metal concentrations followed trend: Fe >> Mn > Zn Pb Cu ? Cr ?Ni Cd. At p = 0.05, (ppm...

Sampling of sediments and aquatic plants was carried out during spring and summer 2014. Results showed that the mean  concentrations of elements in Phragmities ...

the objective of the present study was to evaluate the effect of metal mobilizing agents, ethelynediaminetetraacetic acid (edta) and salicylic acid (sa), on the accumulation and translocation of lead (pb) and nickel (ni) by fenugreek ( trigonellafoenum-graecum l . ) plants in contaminated soil. edta and sa were amended at 100 mm and 1.0 mm respectively. pb and ni content were estimated using ic...

Freshwater quality criteria for iron (Fe), lead (Pb), nickel (Ni), and zinc (Zn) were developed with particular reference to aquatic biota in Malaysia, and based on USEPA's guidelines. Acute toxicity tests were performed on eight different freshwater domestic species in Malaysia which were Macrobrachium lanchesteri (prawn), two fish: Poecilia reticulata and Rasbora sumatrana, Melanoides tubercu...
