background: lead toxicity has been reported to affect hematopoietic, nervous, reproductive, cardiovascular and urinary tract systems. many investigators have so far studied the effects of high blood lead levels on pregnancy outcomes. objective: to investigate the effects of elevated maternal blood lead during pregnancy on some trace elements and pregnancy outcomes. methods: blood lead and plasm...

Flow injection analysis (FIA) system coupled with a computer-controlled auto-pretreatment (Auto-Pret) system (MGC Auto-Pret 018S) was newly developed for the determination of ultra-trace amounts of Pb(II) in aqueous samples. The solid phase material, Analig Pb-01 (GL Sciences), was packed in a mini-column (2 mm i.d. x 40 mm length), which was installed in the Auto-Pret system. In the mini-colum...

A new procedure is presented for the determination of low concentrations of lead and cadmium in water samples. Ligand assisted pseudo-stir bar hollow fiber solid/liquid phase microextraction using sol-gel sorbent reinforced with carbon nanotubes was combined with differential pulse anodic stripping voltammetry for simultaneous determination of cadmium and lead in tap water, and Darongar river w...

A very simple, ultra-sensitive and fairly selective direct spectrophotmetric method is presented for the rapid determination of lead(II) at ultra-trace level using 1,5-diphenylthiocarbazone (dithizone) in micellar media. The presence of the micellar system avoids the previous steps of solvent extraction and reduces the cost and toxicity while enhancing the sensitivity, selectivity and the molar...

This research aims to monitor the trace elements content (Cr, Cu, Pb, Cd, Ag, Al, Mn, Mg, Zn and Fe) in the tissues of the muscle and liver of silver carp (H. molitrix ) and stone moroko (P. parva) from Zarivar Wetland in western Iran. This research was cross-sectional. The research specimen was fish caught from Zarivar Wetland. Metal concentration analysis was carried out utilizing an ICP. Fin...

Background: A sensitive, accurate and precise method was developed and validated in regard to Council Directive 333/2007/EC, Commission Decision 657/2002/EC, ISO/IEC 17025:2005 and EURACHEM 1998 for the trace level determination of Lead (Pb), Cadmium (Cd) and Chromium (Cr) in fish feed samples using Graphite Furnace Atomic Absorption Spectrometry (GF-AAS). Methods: For method validation, select...
