Sadržaj teških metala u odabranim đubrivima koja su u upotrebi u Srbiji.

Levels of heavy metals Cd, Cr, Ni and Pb obtained by analysis of inorganic and organic fertilizers available on the Serbian market are discussed in this paper. The first estimation of the heavy metal input in soils due to use of phosphate fertilizers is also given. The heavy metal contents of all analysed inorganic fertilizers were below the MAC according to the current Serbian regulations. Elevated concentrations of Ni were detected in two and a high Cr concentration in one sample of the substrates. The average (theoretical) heavy metal input in Serbian soils was calculated based on the application of 20 kg ha-1 P2O5 per year. The calculated heavy metal input was lower than European average and it is similar to the inputs recorded in Finland and Denmark. [ABSTRACT FROM AUTHOR]
