Analysis of elements content in honey is important for honey quality and safety and for monitoring of environmental pollution. The levels of 22 elements, aluminum (Al), barium (Ba), calcium (Ca), cadmium (Cd), chromium (Cr), cobalt (Co), iron (Fe), copper (Cu), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), sodium (Na), lead (Pb), strontium (Sr), silver (Ag), bismuth (Bi), gallium ...

The aim of this study was to determine the level of heavy metals such as copper, iron, manganese, zinc, lead, nickel, cadmium and chromium concentrated in Juglans regia bark and leaf samples from different localities in Artvin, Turkey. Analysis of the heavy metals Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr in samples was carried out by inductively coupled plasma optical emission spectroscopy (ICP-OES; P...

Baseline blood concentrations of metals are important references for monitoring metal exposure in environmental and occupational settings. The purpose of this study was to determine the blood levels of manganese (Mn), copper (Cu), zinc (Zn), lead (Pb), and cadmium (Cd) among the residents (aged 12-60 years old) living in the suburb southwest of Beijing in China and to compare the outcomes with ...

In the present study. the metal-containing proteins in the roots ofCu-tole rant plant ElsllOltzia splendens were investigated. The proteins from the plant roots were extracted and separated by two-dimensional gel electrophoresis (2D GE). Las er ablation inductively coupl ed plasma mass spectrometry (LA-ICP-MS) was used to screen metal-containing proteins on the dried 2D gels. Images of Cu. Zn. ...

Novel single cell techniques are attracting growing interest for clinical applications, because they can elucidate the cellular diversity and heterogeneity instead of the average masked by bulk measurements. Herein, time-resolved ICP-MS for the determination of essential mineral elements in single cells has been developed and is used to analyze the contents and distribution patterns of Fe, Cu, ...

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 ...
