Vascular calcification is a prominent feature of atherosclerosis. The mineral composition and quantity within calcified arterial plaques remains unelucidated; therefore, the aim of this study was to analyze the mineral composition of such plaques. Calcified arterial plaques were obtained from patients with abdominal aortic aneurysms (AAAs) and carotid artery stenoses. Calcified aneurysmal plaqu...

BACKGROUND The aim of this paper was the validation of a new analytical method based on the high-resolution continuum source flame atomic absorption spectrometry for the fast-sequential determination of several hazardous/priority hazardous metals (Ag, Cd, Co, Cr, Cu, Ni, Pb and Zn) in soil after microwave assisted digestion in aqua regia. Determinations were performed on the ContrAA 300 (Analyt...

background: cold-induced aggregation micro extraction based (ciame) based on ionic liquid was used as a rapid and simple method for determination trace amounts of cadmium and lead in milk powder by analysis with flame atomic absorption spectrometry (faas). methods: sample solution containing of cd2+ and pb2+ in dynamic range, phosphate buffer (ph = 9, 3 ml), diethyl dithiocarbamate (complexing ...

In this study, potassium vapor was prepared by using carbonate (K2CO3) and activated carbon (C) reagents to simulate the actual situation of adsorbing from sinter in blast furnace. The potassium-rich characterized X-ray diffraction (XRD), flame atomic absorption spectrometry (FAAS), scanning electron microscopy (SEM-EDS). effects content on enrichment ratio, adsorption rate, low-temperature red...

Landscape parks are protected areas, attractive to live close and relax in. In parks, economic agricultural activities allowed a limited extent. The high interest in these areas is the cause of unfavorable changes, including environmental contamination. This paper presents results soil quality research Wzniesienia Łódzkie Park (Poland). analyses were performed 2008, before construction highway ...

A new and simple flame atomic-absorption spectrometric (FAAS) method is proposed for simultaneous determination of iron and copper in children's sera. It is based on single-step sample pretreatment (deproteinization with 3 mol L-1 HCl, ratio 1:1) and single-step calibration using 1.5 mol L-1 HCl standard. During method's optimization a short multifactorial design experiment was used. The propos...

A rapid vortex assisted-cloud point extraction (VA-CPE) method was developed to separate cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) in accordance with important parameters. Cd Pb determined personnel care products (PCPs) by Electrothermal Atomic Absorption Spectrometry (ETAAS), however Cu Zn Flame (FAAS). Triton X-100 xylenol orange were used as a chelating agent. The factors including ...

OBJECTIVES The objectives of this study were to determine the lead levels in blood samples from nielloware workers, to determine airborne lead levels, to describe the workers' hygiene behaviors, and to ascertain and describe any correlations between lead levels in blood samples and lead levels in airborne samples. METHODS Blood samples and airborne samples from 45 nielloware workers were coll...

Polystyrene (PS) was extracted from Styrofoam (expanded polystyrene foam) waste, so called white pollutant. The PS was functionalized with N,NBis(2-aminobenzylidene)benzene-1,2diamine (ABA) ligand through an azo spacer. The resin was characterized by FT-IR spectroscopy and elemental analysis. The PSN=N-ABA resin was used for the enrichment and speciation of Cr(III)/Cr(VI) ions and total Cr dete...
