THE CONTENTS OF SELECTED METALS IN CARROT CULTIVATED USING CONVENTIONAL, INTEGRATED AND ORGANIC METHOD

The experiment was conducted in the years 2006-2008. The research covered carrots, Flakkee 2 c.v. cultivated according to the principles of conventional, inte-grated and organic production.
Organic cultivation was conducted on a certified organic farm.
The vegetables were grown on the farms situated in close vicinity to each other and in similar soils.
The contents of Pb, Cd, Zn, Ni and Cr were determined in the harvested carrot yield and the effect of cultivation method on their concentra¬tions was assessed.
The permissible content of three of the analyzed elements: lead, cadmium and zinc has been determined for vegetables.
The values were not exceeded in any case of the analyzed carrots.
Carrots produced by means of organic method contained signif¬icantly lower quantities of Pb, Cd and Zn than cultivated using conventional method.
The carrots contained also lesser amounts of this metal than the ones grown using integrated method.
No effect of the cultivation method was found on Ni or Cr concen¬trations in carrot roots.
