Badania zawartosci niektorych pierwiastkow sladowych w produktach spozywczych krajowego pochodzenia. Cz.XIX. Zawartosc olowiu, kadmu, chromu, cynku, manganu, miedzi, niklu i zelaza w miodach pszczelich

Metodą spektrometrii atomowo-absorpcyjnej oznaczono zawartości kadmu, ołowiu, chromu, cynku, manganu, miedzi, niklu i żelaza w siedmiu odmianach miodów pszczelich pochodzących ze wschodniej części Polski.

Concentrations of lead, cadmium, chromum, zinc, manganese, copper, nickiel and iron in seven bee honey grades were determined by flame atomic absorption spectrometry. Lead, cadmium and nickel levels were assayed using extraction technique after the metals had been complexed with APDC. Methyl isobutyl ketone was used as the organic phase. The contents of the remaining elements were determined directly from the mineralizates. The following average concentrations were determined: lead from 0,044 mg/kg to 0,118 mg/kg; cadmium from 0,004 mg/kg to 0,016 mg/kg; nickel from 0,042 mg/kg to 0,500 mg/kg; copper from 0,14 mg/kg to 1,37 mg/kg; zinc from 2,69 mg/kg to 19,37 mg/kg; iron form 2,30 mg/kg to 9,46 mg/kg; manganese from 0,51 mg/kg to 10,43 mg/kg and chromium from 0,017 mg/kg to 0,053 mg/kg. The determined values were comparable to, or lower than, the values reported by others authors.
