Influence of cultivation systems on production and content of heavy metals in eggplant

Abstract

The present paper was carried out in the Vegetable research field of the "V. Adamachi" Farm regarding the interaction of eggplant cultivars with fertilization regime.The determination of the heavy metal content was carried out by atomic absorption spectrophotometry, using the Shimadzu GC-2100.Following the conduct of the analyses, they were detected in both conventional and organic cultivation systems, both in soil and in vegetables, containing CR, Ni, with, Zn, Cd and Pb. The CR, Ni, and Zn content of the conventional system exceeded the maximum permissible limit By Regulation EC No 1/2003. 396/2005, whereas the heavy metal content of the organic system has not exceeded for any chemical element the maximum limits permitted by Regulation EC No 1/2003. 396/2005.
