Zawartosc rteci we wlosach mieszkancow Warszawy narazonych i nienarazonych zawodowo

Abstract

Określono stopień narażenia na rtęć ludzi zamieszkałych na terenie Warszawy i okolic na podstawie oznaczeń tego pierwiastka we włosach osobników nienarażonych oraz narażonych zawodowo. Oznaczenia wykonywano metodą spektrofotometrii atomowo-absorpcyjnej.The concentrations of mercury in the hair of workers employed in the fluorescent tubes plant in Warsaw were determined and compared with the results obtained in our previous studies in the years 1970/1980. Total mercury in the hair was analysed by means of flameless atomic absorption spectrometry. The average mercury concentrations in the non-exposed population was at a similar level (0.17 µg/g) as in the results obtained in 1970/80. The average concentrations of total mercury in the hair of exposed subjects were approximately 30 times lower than in the years 1970/80 and ranged from 0.38 to 1.42 µg/g. This substantial reduction in Hg concentration in the hair of exposed people was due to improvements in the technological process
