Abstract:
Concentration of heavy metals and inorganic cations were measured in the soil and composite
samples of sugar beet pulp of bulk storage taken from two sites in Bačka and one in the Srem
region (Serbia). Inorganic cations (K+, Na+, Ca2+,
and Mg2+ in mg/kg) were determined by flame atomic absorption
spectrophotometric technique. The contents of Pb, As, Cd (μg/kg), Cu, and Fe (mg/kg) were a
nalysed by a flameless atomic absorption spectrophotometer equipped with graphite furnace and
Hg (μg/kg) with hydride generation. In the soil of the South Bačka region, the main
plant-available cations were Fe, Pb, Zn, and Cd and in the sugar beet pulp Fe, Zn, and Cd, while
the concentrations of heavy metals were negligible substantiating that sugar beet pulp was a safe
product for making either feed mashes or fiber rich food additives and other similar products.
