Metodą spektrometrii atomowo-absorpcyjnej oznaczono zawartość kadmu, ołowiu, chromu, cynku, manganu, miedzi, niklu i żelaza w jednoskładnikowych przyprawach roślinnych najczęściej używanych w procesach kulinarnych i przemyśle spożywczym.

Cadmium, lead, chromium, zinc, manganese, copper, nickel and iron contents of some vegetable spices were determined by atomic absorption spectroscopy using air-acetylene flame. Cadmium, lead and nickel were assayed using extraction technique after the metals had been complexed with APDC. Methyl isobutyl ketone was used as the organic phase. There were considerable differences between the results for the individual spice grades, which were attributable probably to the origin of the material (local or foregin), the organ of the vegetable form which the spice had been made, and processing method used to produce the spice (e. g. grinding). The following average concentrations were found: cadmium form 0,008 to 0,520 ppm, lead from 0,165 to 6,238 ppm, chromium from 0,000 to 3,160 ppm, zinc from 5,65 to 107,80 ppm, manganese from 5,00 to 590,00 ppm, copper from 4,67 to 15,30 ppm, nickel from 0,250 to 5,850 ppm, and iron from 20,00 to 1092,00 ppm.
