Determination of Trace Elements in Sea Food by Solid Sampling Zeeman Atomic Absorption Spectrometry (SSZAAS)

Direct solid sampling Zeeman atomic absorption spectroscopic (SSZAAS) methods were developed and applied to the determination of cadmium, mercury, manganese, lead and tin in sea food. All elements but mercury were measured by a third generation ZAAS combined with an automatic solid sampler. In 3-field- and dynamic mode the calibrations concentration 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 (CRMs) of organic matrices. In case solid CRMs were not available calibration by aqueous standard solutions was proved to be an alternative. No matrix effects were observed under the optimised conditions. Results obtained were in good agreement with the certified values. SSZAAS proved to be a reliable, rapid and low-cost method for the determination of trace elements in sea food.
