Abstract A method has been developed for determination of arsenic in beer. Organic matter is destroyed by the dry-ashing technique, the ash is dissolved in HC1, and hydrides of arsenic are generated by addition of sodium borohydride prior to atomization in a flame-heated quartz cell and atomic absorption spectroscopy measurement. The analytical features of the method are detection limit 0.1 ng/g beer, precision 8%, and recovery 97 ± 7%. The arsenic contents of different brands from Spain and other European countries were analyzed. In all samples, the arsenic levels found were well below maximum levels allowed in Spanish legislation (100 ng/g). The quantities of arsenic in Spanish beers do not differ from those found in foreign beers. No differences were found between bottled and canned beers, and no correlation exists between metal content and original specific gravity of the beers.

Arsenic Determination

Amethod for the determination of traces of arsenic in food has been developed based on electrolytic arsine generation and atomic absorption spectroscopy detection. The essence of the method is the addition of copper and tin salts to the electrolyte solution, enabling a fast and effective arsine evolution. The advantage of this method lies in the fact that it enables the simultaneous concentration of heavymetals, such as cadmium and lead, on cathode. The applicability of themethod was illustrated by determining the arsenic content in some food samples based on vegetable oils and by comparing the results with those obtained by the classical technique of chemical hydriding with sodium tetrahydroborate.
