Copper in Surface Layer of Vineyard Soils on Island Hvar
Th e frequent use of copper fungicides in grape production results in increased accumulation of total copper in the surface layer of vineyard soils. Th e objective of this research was to survey copper concentration and determine degree of pollution or contamination with copper in surface soils of vineyards on island Hvar. Sampling was undertaken on anthropogenic colluvial soils, anthropogenic terrace soils on pleistocene calcareous aeolian sands and anthropogenic soils on quaternary alluvial, aeolian and diluvium depositions. Concentrations of total copper in the vineyard soils under research range from 50.60276.33 mg kg-1. Copper concentrations were signifi cantly (p<0.01) higher in anthropogenic soils on quaternary alluvial, aeolian and diluvium depositions than on other soils sites tested. According to the specifi cations provided within the “Regulations on Protection of Cultivated Land from Contamination by Hazardous Substances” (NN 9/14) sixteen out of twentyseven vineyard soils under research were polluted and fi ve were contaminated with copper. Th e results of this research provide further data relevant to the inventory of heavy metals in vineyard soils of this part of the Croatia.
