Introduction: Today, bottled waters have attracted the assurance of consumers as one of the important drinking water supply resources, such that in some regions, the use of bottled waters has replaced the drinking water distribution system. The present study was carried out with the aim of measuring and determining the heavy metals in bottled water across a number of brands produced in Iran and...
متن کاملDetermination of some trace metals by FAAS after solid-phase extraction with amberlite XAD-1180/TAN chelating resin.
A new chelating resin was synthesized by immobilizing 1-(2-thiazolylazo)-2-naphthol through the -N=N- group on Amberlite XAD-1180. The resin was used for the preconcentration of Cd(II), Co(II), Cu(II), Mn(II), Ni(II), and Pb(II) ions and their determination by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters, such as the pH, volume of the sample, flow ra...
متن کاملBlood concentration of essential trace elements and heavy metals in workers exposed to lead and cadmium.
The aim of the study was to determine blood concentration of essential trace elements (Se, Zn, Cu) and toxic metals (Pb, Cd), markers of antioxidant (activities of glutathione peroxidase (GPx), superoxidase dismutase and ceruloplasmin) and prooxidant processes (thiobarbituric acid reactive substances (TBARS)) in workers exposed to Pb and Cd. Forty three male workers of the lead-acid batteries d...
