Measurements of lead and cadmium content by AAS, and fluorine content by spectrophotometry based on complexing with alizarin, were carried out in vegetables and fruits harvested in 1989 in Inowrocław region. The highest lead concentration (on an average from 0.553 to 1.003 mg/kg of fresh product) was noted in overground of vegetables. Lead concentration in subterranean shoots did not exceed the tolerance limit of 0.3 mg/kg of fresh product, recommended by the Polish Standard. Maximum contamination with cadmium (on an average 0.052 mg/kg fresh product) was found in vegetables harvested in city gardens (the control area) whereas that in allotments varied from 0.023 to 0.052 mg/kg. Plants contamination with fluorine was not large and concerned only overground parts of marjoran, parsley leaves, onion leaves, and celery.
