The hollow cathode lamp specific for lead was inserted into the ETAAS. The wavelength was adjusted to 283.3 nm and the instrument was standardized and calibrated with standard blank and lead standard.
As shown in Table 14, the most commonly used techniques to obtain the elemental concentration of heavy metals are AAS, AFS, AM A, CVAAS, CVAFS, ETAAS, FAAS, GFAAS, ICP-ES, ICP-MS, and ICPOES XRF [114-116].

Prepared samples were subjected to electrothermal atomic absorption spectrophotometer (ETAAS) for estimation of Pb and Cd.
Recently, various types of analytical techniques, such as electrothermal atomic absorption spectroscopy, (ETAAS) electrothermal vaporization inductively coupled plasma- mass spectrometry, hydride generation atomic- absorption spectroscopy and hydride generation atomic fluorescence spectrometry have been used for the determination of the low concentration levels of As [4].
Direct analysis using little or no sample preparation is most suitable for electrothermal atomic absorption spectroscopy (ETAAS) with a graphite tube furnace and X-ray fluorescence (XRF) [15, 16].

Pb was analysed by means of electrothermal atomic absorption spectrometry (ETAAS) using Varian 220 apparatus equipped with the Zeeman background correction.
In the laboratory the samples of liver and dorsal muscle tissue from the fish and the isopods were prepared for the analyses of Fe, Mn, Zn, Cu, Cd, Pb, and Ni content by electrothermal atomic absorption spectrometry (ETAAS; Varian SpectrAA400) and Hg by cold vapour atomic absorption spectro-photometry (CVAAS; Perkin Elmer MAS-SOB), see Voigt, 2004.
During the last decade one of the most promising possibilities for the determination of microelements by electrothermal atomic absorption spectrometry (ETAAS) in the environment, including seawater, was the use of a colloidal palladium modifier [10, 19].
