“…Neither Parkpian et al (2003) in Thailand nor Ataro et al (2008) in South Africa was able to detect cadmium in analysed samples. Very low values are found by Tripathi et al (1999), Serdaru et al (2001), Licata et al (2004) and Vidovic et al (2005). Low values are also reported by Sola-Larrañaga and Navarro-Blasco (2009) in Spain, but in another area of the country.…”

“…On the contrary, the values obtained for lead are considerably lower than the obtained ones in India (Singh et al 1997;Swarup et al 2005), Argentina (Rubio et al 1998), Spain (Rodríguez Rodríguez et al 1999, Turkey (Simsek et al 2000;Ayar et al 2009), Romania (Serdaru et al 2001), Croatia (Pavlovic et al 2004), Chile (Muñoz et al 2005) or in Mexico (Rodríguez Fuentes et al 2008). The difference is a great deal more pronounced by the worrying results registered by Lopez Mahia et al (1991) in Spain, for Santos et al (2004) in Brazil, Baranowska et al (2005) in Poland and Swarup et al (2005) in India.…”

“…The determination of the residual concentrations of metals in milk could be an important direct indicator of the hygienic status of the milk and an indirect indicator of the level of pollution of the area in which the milk was produced (Simsek et al 2000;Serdaru et al 2001;Licata et al 2004;Pavlovic et al 2004;Ghindini et al 2005). It can be stated that high levels of cadmium and lead in milk could be a potential risk and a public health problem (Pavlovic et al 2004;Swarup et al 2005).…”

The levels of cadmium and lead in 36 raw bovine milk samples were analysed. These samples come from seven farms with a semi-extensive grazing system and were collected between the autumn of 2007 and the winter of 2008. All the farms were located in Asturias (Spain), a zone of great industrial and mining activity in the proximities of the Caudal River. The samples were collected in sterile precleaned polypropylene tubes and frozen until the analysis. After a lyophilization process, the samples were treated with nitric acid and microwave treatment. Cadmium and lead determinations were carried out using inductively coupled plasma mass spectrometry with sensibility under 0.2 ppb for liquid matrix. The lead content was found to vary from 0.71 to 16.06 μg/kg wet weight (w.w.), and the cadmium was lower than 2 μg/kg w.w. The levels of lead in milk are higher in those farms near zones of storage of mining waste depots, thermal power and areas with high levels of traffic. All the values found are in concordance with research carried out at non-polluted areas, and those for the lead are well below the European Union limitations.

“…Flame atomic absorption spectrometry (FAAS) is the most widely used technique for the metal determinations because most of the concentrations of metals in environmental samples are readily determined using this technique (Serdaru et al 2001;Bakirdere andYaman 2007, Kiptoo et al 2008). Furthermore AAS is cheap and its usage is easier than other instruments.…”

Cu, Ni, Pb, Fe, Mn, Cr and Cd contents were determined in 17 different brands of chewing gum and candy samples available in local markets of Kayseri, Turkey. Concentration of selected trace metals were estimated using flame atomic absorption spectrometer after dry and wet digestion methods. Out of 17 brands of chewing gums and candies analysed, four were cocoa based, two were sugar based and other were of fruit based. Copper level ranged from 0.219 to 2.455 microg/g with an average of 1.390 microg/g. Nickel ranged from 0.120 to 2.588 microg/g with an average of 0.846 microg/g. Lead level ranged from 0.031 to 2.46 microg/g with an average of 0.746 microg/g. Iron level ranged from 3.963 to 9.863 microg/g with an average of 6.618 microg/g. Manganese level ranged from 1.872 to 5.067 microg/g with an average of 3.196 microg/g. Chromium ranged from 0.740 to 6.265 microg/g with an average of 2.473 microg/g and cadmium level ranged from 0.027 to 0.825 microg/g with an average of 0.296 microg/g. Cocoa based samples were found to have higher contents of the analysed metals than sugar and fruit based samples.

“…The elements present in tea samples have been reported in the literature. [26][27][28][29][30] Furthermore AAS is cheap and its usage is easier than other instruments. The mineralization of biological and environmental matrices by microwave digestion has been gaining wider acceptance in recent years.…”

Comparison of Sample Preparation Procedures for the Determination of Trace Heavy Metals in House Dust, Tobacco and Tea Samples by Atomic Absorption Spectrometry

2004

The effect of wet ashing, dry ashing and microwave procedure for the determination of trace metal levels was investigated in house dust, tobacco and tea samples by atomic absorption spectrometry. The study of sample preparation procedures showed that the microwave method was the best. The recovery of trace metals was very good and precision and accuracy were compatible with standard reference material. The relative standard deviations for all measured metal concentrations were lower than 10%. The digestions of HNO3/H2SO4/HClO4 (4: 1: 1) mixture for house dust, HNO3/H2SO4/H2O2 (2: 2: 2) mixture for tea and HNO3/H2O2 (4: 2) mixture for tobacco were very efficient.
