Trace metal (Fe, Co, Ni, Cu, Zn, Cd, and Pb) concentrations in zooplankton from the mixed layer were investigated at 8 coastal and 20 offshore stations in the western Bay of Bengal during the summer monsoon of 2003. The ecotoxicological importance of trace metal uptake was apparent within the Bay of Bengal zooplankton. There was a distinct spatial heterogeneity of metals, with highest concentra...

The purpose of the study was to investigate the mineralogical and Heavy Metals (HMs) present in the granite mining soils in Chimakurthy, India. The mineral exploration of mining soils were identified by X-Ray Diffractometer (XRD) pattern analysis. However, the morphological features and quantitative HMs were detected by Scanning Electron Microscopy/Energy Dispersed Spectroscopy (SEM/...

Concentrations of the elements Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, N, Ni, P, Pb, and Zn were measured in needles and bark of Taxus baccata from the urban environment of Wrocław, Poland, and from a control site relatively free from pollution. In Wrocław the concentrations of N, P, K, and Mg in needles were significantly higher than in bark, but concentrations of Cd, Co, Cr, Cu Fe, Ni, and Zn were...

dietary intake is the most important route of exposure to heavy metals for most people. rice is a staple food for iranians that, if polluted, threatens public health. cooking process may affect heavy metals content of rice. in this study, concentrations of cadmium (cd), lead (pb), chromium (cr), nickel (ni) and cobalt (co) were measured in 3 brands of imported rice available in shiraz-iran mark...

We examined the concentrations of chromium (Cr), nickel (Ni), cadmium (Cd) and lead (Pb) in Rook Corvus frugilegus eggshells from 43 rookeries situated in rural and urban areas of western (=intensive agriculture) and eastern (=extensive agriculture) Poland. We found small ranges in the overall level of Cr (the difference between the extreme values was 1.8-fold; range of concentrations=5.21-9.40...

Toxicity has occurred in workers exposed to nickel dust or nickel carbonyl formed in refining. Increased risk of nasal and lung cancers was linked to occupational nickel exposure before current workplace safety standards were set. Activated carbon with nano holes used for removing contaminants in environment. The purpose of this work is preparation a new nano-absorber, GZ-BAKI-TAC-Ni-88, for th...

Various morphologies of multi-walled carbon nanotubes (MWNTs) are grown catalytically on metalalloy probes in counterflow diffusion flames using methane as fuel. Carbon nanotube (CNT) properties and morphologies are investigated as functions of local gas-phase temperatures, C-related species concentrations (e.g. C2H2, CO), sampling positions, C2H2 adding to the fuel, and metal-alloy composition...

Over the years, there has been an obvious pollution problem in Lagos area, Nigeria with high population of over eleven million and the near absence of waste management infrastructures. Concentrations of some pollution parameters and trace elements (temperature, pH, salinity, SO42-, NO3-, PO43-, F-, DO, BOD, COD and coliform, Cr, Co, Ni, Ag, Cd and Pb) were determined from water bodies of Isolo ...
