“…The solid sampling has been utilized for determination of mercury in several matrices as: contaminated soils [51], airborne particulate matter [52], polymers [53], biological samples [54,55], but its application for food analysis has been limited. Methods have been established for determination of mercury in fish [56], tuna fish [50], milk powder [50], spinach [57], seafood [58] and fish [59]. The Table 3 shows analytical parameters of methods proposed for determination of mercury in food samples.…”

“…In a recent study (Grobecker and Detcheva 2006), we have already referred to the good agreement of liquid and solid calibration for mercury measurements. A linear calibration curve produced by the application of organic and inorganic materials for solid calibration indicates also that direct SS-ZAAS mercury determination is matrix independent.…”

“…The instrument is equipped with a specially designed furnace (Grobecker and Detcheva 2006) permanently heated at a constant temperature of 1,000°C. Samples are weighed on a micro-balance (Sartorius 4503 MP6, Germany) in platinum transport boats of 250 ll volume.…”

Direct solid sampling Zeeman atomic absorption spectrometric methods were developed and successfully applied to the determination of mercury, cadmium, lead and manganese in aquatic plants. Mercury was determined using a specially designed furnace. The other elements were determined by a third generation spectrometer. In 3-field-and dynamic mode the working range was substantially extended and high amounts of analyte were detectable without laborious dilution of solid samples. The measurements were based on calibrations using certified reference materials of organic origin. No matrix effects were observed under the optimised conditions. Results obtained were in good agreement with the certified values.

“…Analyses of slurries (1-50 mg mL −1 ; i.e., injection into the graphite atomizer of 10-20 μL of 1-5% m/v slurry) and solid microsamples (0.05-1 mg) have been successfully commercialized and automated in ETAAS. This approach exhibits numerous advantages and is highly valued in the literature-see recent reviews and discussions on SS-ETAAS (141,150,158,159) and SoS-ETAAS (133,150,160). Multielement analysis of slurries (five to six elements) is possible with SS-ETAAS (158) and by true simultaneous SS-ICP-AES (133,161) and ETV-ICP-AES (162) as recently reviewed by Resano et al (150).…”

The study of the ionome (ionomics) is defined as quantitative and simultaneous measurement of the element composition of living organisms and changes in this composition in response to physiological stimuli, development stage, and genetic modifications (Salt et al., Ann. Rev. Plant Biol., Vol. 59, 2008). The necessity of understanding the regulation processes of elements in the organisms demands determination of many elements in the organism, tissue, and cell (Baxter, Plant Biol., Vol. 12, 2009) . A prospect for ionomics is environmental pollution where great variety of conditions and pollutants exist resulting in concentration and interelemental changes in the plant ionome. The capabilities of and problems with several multielement analytical techniques, including instrumental neutron activation analysis (INAA), X-ray fluorescence, inductively coupled plasma-atomic emission spectrometry (ICP-AES), inductively coupled plasma-mass spectrometry (ICP-MS), and atomic absorption spectrometry (AAS), which are adequate and most promising in ionomic and environmental studies of plants, are reviewed. References are confined mainly to the last 10-15 years. Information about concentrations, roles, binding forms, and pollution sources of the elements and comparison between methods with respect to limits of detection, determined elements, interferences, and economic considerations are tabulated. Some combinations of instrumental techniques supplementing each other are highly valued, namely, ICP-MS and ICP-AES and INAA and AAS or ICP-AES.
