Simultaneous determination of trace lead and cadmium in water samples by adsorptive stripping voltammetry using gallic acid as a selective chelating agent
This work describes a procedure for the simultaneous determination of cadmium and lead in some food and water samples using an adsorptive stripping voltammetric method. The method is based on the adsorptive accumulation of 2,3,4-trihydroxybenzoic acid (gallic acid (GA)) complexes of these elements onto a hanging mercury drop electrode, followed by the reduction of the adsorbed species. ...

Guidelines for drinking water quality Addendum to Vol 2 Health Criteria
In 1984 and 1985, the World Health Organization (WHO) published the first edition of Guidelines for drinking-water quality in three volumes. The development of these guidelines was organized and carried out jointly by WHO headquarters and the WHO Regional Office for Europe (EURO). In 1988, the decision was made within WHO to initiate the revision of the guidelines. The work was again shared ...

Concentrations of heavy metals in plants grown on polluted mining soils (Loma Charra mine, Spain)
Evaluation of heavy metal accumulation in plants is of environmental importance due to its toxicity effects in humans and other biota. Soils and plants were sampled in a polluted site around a Pb-Zn(Cd) mine. Total metal contents in the soil indicate a gross degree of pollution in relation to background levels. Soil Cd shows high mobility and availability and consequent high environmental risk. ...

Solid phase extraction of trace amounts of cadmium(II) ions in water and food samples using iron magnetite nanoparticles modified by sodium dodecyl sulfate and 2-mercaptobenzothiazole
A new, simple and rapid method for solid phase extraction and preconcentration of trace amounts of cadmium ions using 2-mercaptobenzothiazole/sodium dodecyl sulfate immobilized on magnetite nanoparticles (MBT-SDS-MNPs) was proposed. The method is based on the extraction of cadmium ions via complexation with MBT immobilized on SDS-coated MNPs and their determination by flame atomic absorption ...

Measurement of Trace Elements in Fruit Juice and Various Food Matrices Using Ultrasonic Nebulization with ICP-AES Detection
Consumers have become more concerned about the levels of potentially toxic trace elements such as arsenic, cadmium, and lead in beverages and food. Of specific concern are products intended for consumption by children. Reliable and precise methods of food analysis are important to maintain the safety of the food supply. In addition, accurate data is necessary to comply with food labeling ...
