Über den bleigehalt in den ungarischen weinen

Abstract
The authors have investigated the lead content of 560 hungarian wines produced between 1969 and 1973 by atomic absorption spectrophotometry (Type of instrument: UNICAM SP 1900). The preparation of samples was made by wet digestion with HNO3- H2O2. For 94.12% of the investigated wines less than 0.4 ppm lead content was established. The 2.67% of wines contain 0.4–0.6 ppm lead. In case of 18 samples (3.21 %) more than 0.6 ppm lead content was found. 560 mit HNO3 veraschte ungarische Weine der Jahrgänge 1969–1973 wurden mit der Atomabsorptionsmethode auf ihren Pb-Gehalt untersucht. 94;1 % hatten einen Pb-Gehalt < 0,4 ppm, 2,7 % einen solchen von 0,4–0,6 ppm. Bei 18 Proben (3,2%) lag der Pb-Gehalt über 0,6 ppm.
