“…The volume of the resulting extract was measured and 1 ml was removed for subsequent analysis of lead and cadmium by GF-AAS. The remaining extract was used for arsenic determination according to Mindak and Dolan (1999). Briefly, the microwave extract was transferred to a glass beaker containing 2 ml ashing aid (2% MgO suspension in 20% Mg (NO 3 ) 2 .6H2O solution m/v) and carefully heated on a hotplate until dry.…”

Fifty-four canned tuna fish samples corresponding to 10 widely used different brands were purchased from local markets in Tehran, Iran during 2012-2013 and analysed on heavy metals. Mercury was determined by a direct mercury analyser without any sample preparation. For analysis of other elements samples were digested using a microwave apparatus. Lead and cadmium were determined by graphite furnace atomic absorption spectrometry and arsenic via hydride vapour generation. All samples had arsenic and mercury contamination. Arsenic levels showed a range of 0.25-1.42 mg kg(-1), which might be due to lack of national and international limits for arsenic in canned tuna fish. Lead and cadmium were measured in a small number of samples with a mean of 0.053 ± 0.058 mg kg(-1) and 0.013 ± 0.015 mg kg(-1), respectively. Results obtained for these heavy metals in all samples were lower than the corresponding limits, whereas arsenic and mercury contents might raise some attention.

“…To analyze trace selenium, there are various methods currently available (Foster and Sumar, 1995) including neutron activation analysis (Slejkovec et al, 2000), atomic fluorescence spectrometry (Pappa et al, 2006;Semenova et al, 2003;Tinggi et al, 1992), atomic absorption spectrometry (AAS) using either electrothermal atomization (Hussein and Bruggeman, 1999) or hydride generation method (Mindak and Dolan, 1999;Tinggi et al, 1992), and inductively coupled plasma spectrometry (ICP) (Kim et al, 1990;Masson et al, 2005;Featherstone et al, 2004) and ICP/ mass spectrometry (MS) (Park and Kim, 2001). For this study, ICP-MS for the analysis of selenium has been optimized and applied because of low detection limit and high efficiency.…”

“…Detection limit of 0.18 ng mL À1 was obtained by Rupasinghe et al (2004). Mindak and Dolan (1999) described a limit of detection of 0.05 ng mL À1 and estimated 10 mg kg À1 as a limit of quantification in samples based on 1 g aliquots of samples. These limits were smaller than those established in this paper.…”

“…In Brazil, the monitoring of this element in animal tissues (muscle, kidney and liver) is regulated by PNCRB, a Ministry of Agriculture and Livestock program for control of residues and contaminants in food of animal origin (Brasil, 2005). In spite of the fact that liver has been described as a difficult matrix (Mindak and Dolan, 1999), this tissue was selected by the PNCRB as a priority for validation studies. Several methods have been described for the determination of arsenic.…”
