ABSTRACT
The study reports on the amount of lead and cadmium in selected samples of vegetables obtained directly from Warmian-Masurian producers, and commercial samples from a deep-frozen food producer. Concentration of analysed compounds after dry mineralisation of biological material and organic phase extraction (APDC/MBIK) has been determined using the atomic absorption spectrophotometry (AAS) in a UNICAM 939 AA apparatus.
There has been significantly high concentration of lead in the samples of cauliflower (0.95 mg/kg) and carrot (0.98 mg/kg). In commercial samples the difference was statistically significant. Whereas significantly higher concentration of cadmium has been detected in spinach both in producer and commercial samples (0.092 and 0.086 mg/kg respectively). Generally, concentration of metals determined was similar in vegetable samples obtained from the suppliers and in commercial ones.
The researched vegetables were characterised by lower concentration of particular compounds compared to valid legal regulations.
