[Study of fluorine and lead levels in selected vegetables and fruit grown within the range of emission of these elements by the household glass plant "Irena" in Inowrocław].

The content of fluorine and lead was determined by spectroscopic methods in the vegetables, fruit and flowers gathered in 1987 from the "Transportowiec" Garden Plots situated in the range of emission of these elements by the plant. Fluorine was isolated from plant materials by microdiffusion and determined spectrophotometrically as a triple complex: alizarine complexon + lanthanum + fluorideion. Lead was determined by atomic absorption spectrophotometry (ASA). Vegetables and fruit were raised in the range of 500 m from the emission source of the "Irena" plant. In only several vegetables the content of fluorine calculated for dry mass exceeded the Polish permissible level. On the other hand, the lead content in vegetables exceeded in 18.5% the Polish normal value and the suggested normal value of the Council of Mutual Economic Aid countries in 55.5%. The obtained results of fluorine and lead determinations were compared with those in the years 1981-1983 stressing the health hazards caused by consumption of vegetables and fruit from the gardens and fields situated in the vicinity of glass plant emission sources.
