Concentrations of lead, cadmium, nickel, zinc, copper and chromium in chilled fruits were determined by atomic absorption spectrometry (AAS) The following average values, related to the wet weight, were determined: lead - from 0,085 mg/kg (strawberry) to 0,205 mg/kg (five-fruit compote composition); cadmium - from 0,009 mg/kg (plum) to 0,032 mg/kg (Aronia melanocarpa); nickel - from 0,074 mg/kg (plum) to 0,345 mg/kg (Aronia melanocarpa); zinc - from 0,95 mg/kg (sour cherry) to 3,10 (raspberry); copper - from 0,54 mg/kg (plum) to 1,44 mg/kg (blueberry); chromium - from 0,128 m/kg (raspberry) to 0,470 mg/kg (five-fruit compote composition). Our results comparable with the literature data. The concentrations of the toxic elements (lead and cadmium) were found to remain within the limits specified by relevant standards.
