A method used to determine Pb in unknown matrices by isotope dilution mass spectrometry (IDMS) was previously published by NIST [1]. IDMS is considered the most accurate method for total blood metals analyses, mainly because it eliminates the blood’s matrix effect [2, 3]. However, the IDMS method is relatively expensive, and cannot be used for mono-isotopic metals such as Mn or As. Alternativel...

It is well-documented that organic compounds form strong complexes with most metals in aquatic systems, and that seawater is a complex medium which contains a large variety of organic and inorganic ligands, including colloidal matter. We suggest that most trace metals are complexed in seawater and that some inorganic metals complexes are either labile or not stable. In contrast, metal-organic c...

The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from various places in Bielsko Biata and the neighbouring area. Samples were digested by the wet method in a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified refere...

background: in the present study, blood serum level of metals were determined in malarial pa­tients and compared with those in the normal subjects without complication using atomic absorp­tion spectrometer. methods: for the determination of these metals twelve intravenous blood samples each from re­ferred malarial patients and a group of normal subjects were collected and immediately centri­fug...

background: exposure to heavy metals in development of many diseases has been investigated previously, specially created by oxidative stress. the etiology of rheumatoid arthritis (ra) is still not fully understood but oxidative stress created by heavy metals may have role in development of ra. the aim of present study was to compare serum level of heavy metals in ra and healthy control individu...
