On the content of arsenic, lead, copper, zinc, tin and iron in bottled fruit, strained fruit pulp and bottled jam produced in Poland.

One hundred and fifty-three samples of bottled fruit, strained fruit pulps and jams contained in glass jars were analysed for heavy metals. All arsenic concentrations were less than the limit of detection of 0.04 mg/kg as were all tin concentrations for which the limit of detection was 8 mg/kg. The concentrations of the lead were all below 0.2 mg/kg for bottled fruit and 0.3 mg/kg for stained pulps and jams. In bottled fruit 98% of samples contained less than 3 mg/kg of copper, 98% less than 5 mg/kg of zinc and 97% less than 10 mg/kg of iron. In strained pulps all samples contained less than 2 mg/kg of copper and less than 5 mg/kg of zinc, 41% of samples contained less than 20 mg/kg of iron. In jams all samples contained less than 2 mg/kg of copper and less than 5 mg/kg of zinc, 96% samples contained less than 20 mg/kg of iron.
