“…However, the natural or anthropogenic sources have produced very high levels of arsenic in certain regions around the world. Foods are also considered an important part of the arsenic intake and there are only few reports of arsenic content in vegetables grown in non-polluted soils (Chakraborti et (Jonge et al 2010), fl ame atomic absorption spectrometry (F-AAS), (Tang et al 2012) electro-thermal atomic absorption spectrometry (ET-AAS), (Mizuguchi et al 2011, Mohammadi et al 2012 and cold vapor atomic absorption spectrometry (CV-AAS), (Skoog et al 2002) are used for the determination of heavy metals in environment samples.…”

Abstract:In this study, heavy metals pollutions in waters, soils and vegetables were investigated from farms, near oil refi nery in south of Tehran city, Iran (Shahre Ray). The most important heavy metals in Iranian oil are vanadium, cobalt, nickel, arsenic and mercury (V, Co, Ni, As, Hg). In this region, the concentration of heavy metals in soils, well waters and leafy edible vegetables were evaluated in ten different points of farms. Geographic information systems (GIS) were used to estimate the levels of heavy metals concentration at unmeasured locations. After sample preparation, concentrations of heavy metals in vegetables, soils and waters were determined by atomic absorption spectrometry (AAS). Five different leafy edible vegetables from farms, i.e., Persian leek, dill, parsley, spinach and radish were sampled in spring, summer and autumn 2012. In vegetables and well water samples, the concentrations of V, Ni and Co were above the permissible limit of heavy metals as compared to WHO guidelines and the concentrations of these metals in agricultural soils were found to be lower in accordance to soil references. The industrial waste waters had high concentration of heavy metals in this area. In consequence, the results of this study indicate that industrial waste water can cause pollution in well waters and edible vegetables. So, this region is not suitable for cultivation and growing vegetables.Unauthenticated Download Date | 5/13/18 2:45 AM

“…It is necessary and important to develop sensitive methods for determining heavy metals in soil, and water samples and then, the results must be compared with World Health Organization (WHO) and Environmental Protection Agency (EPA) [25,26]. Various techniques such as, inductively coupled plasma mass spectrometry [27,28], flame atomic absorption spectrometry (F-AAS) [29], electrothermal atomic absorption spectrometry (ET-AAS) [30,31] and cold vapor atomic absorption spectrometry(CV-AAS) [32] have been applied for the determination of soil and water samples. The aim of this study was to monitor the toxic heavy metals such as, Cd, Cr, Ni, Co, and Pb in well waters, drinking waters, waste waters and soils in Isfahan's industrial regions and evaluation of environmental pollution in this area.…”

In this study, soils, well waters, drinking waters, and waste water in the Isfahan industrial area were sampled in spring and summer 2018. In 8 points of industrial zone, important toxic heavy metals such as, lead (Pb), Cobalt (Co), Nickel (Ni), Chromium (Cr), and Cadmium (Cd) were sampled from surface soil (up to 2 m), well/drinking waters and waste water. After sample preparation with micro-wave digestion technique, the concentration of heavy metals was determined by electro-thermal atomic absorption spectrometry (ET-AAS). According to the well water analysis, the mean concentration of Cr, Ni, Co, Cd, and Pb in well water were 95 μg L-1, 146 μg L-1, 185 μg L-1, 12 μg L-1, and 11 μg L-1, respectively. In well water, the concentrations of Cd, Ni, Cr and Co were found much higher than Pb in comparison with the references of World Health Organization (WHO).

“…Various techniques such as inductively coupled plasma mass spectrometry [15], luminescence quenching [16], voltammetry [17], co-precipitation [18], flame atomic absorption spectrometry (faas) [19], neutron activation analysis (naa) [20], inductively coupled plasma optical emission spectrometry (icpoes) [21] and electro-thermal atomic absorption spectrometry (et-aas) [22,23] have been applied for the determination of lead in water samples. Among them, faas has been a very attractive technique for routine metal determinations, due to ease of operation, and low acquisition and operating costs compared with others.…”

In this study, a simple, sensitive and accurate method was developed for the determination of lead ion by combining ionic liquid dispersive liquid-liquid extraction (IL-DLLE) with flame atomic absorption spectrometry. Tetraethylthiuram disulfide (TETD), acetone and 1-octyl-3-methylimidazolium hexafluorophosphate [(C8MIM) (PF6)] were used as the chelating agent, dispersive and extraction solvent, respectively. Under the optimal onditions, the calibration graph was linear in the range of 5-190 μg L-1 of lead and the detection limit was 0.8 μg L-1 with a sample volume of 200 mL. The proposed method was validated by the analysis of one certified reference material and applied successfully to the determination of lead in real water samples.
