Background & aims: Lead poisoning is a global problem and considered to be the most important environmental disease in children. Exposure to even low amounts of lead is dangerous. Lead containing eye make ups due to the long time contact with skin and eye mucosa can lead to blood and eye symptoms. The purpose of this study was to evaluate the amount of lead in powders of kohl in Kerman. Method:...

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

extraction of trace amounts of toxic heavy metals from complicated environmental matrixes is a  challenging task. the aim of this investigation is the comparison of the extraction efficiencies and other related experimental variables ( chemicals, effect of ph, potential interfering ions) on the determination of inorganic lead ( ) which is present in waste water of dye industries. compared techn...
