Pesticide and Toxic Metal Pollution in Waters, Fish and Wild Animals in Vojvodina, Serbia

Abstract

High concentrations of pesticides and toxic metal pollutants in the environment, often present in surface waters in nature, can accumulate in wild animals and are a significant public health concern. Serbia is a moderately developed, south European country in transition, with a long tradition in agriculture, particularly in the northern part, Vojvodina. Our study aimed to assess the presence of pesticides and to measure concentrations of toxic metals in the district of Backi Petrovac, Vojvodina. Water samples were analyzed from canals, ditches, fish from the canals and wild animals caught in the Backi Petrovac district. We identified nine pesticides in water samples. Of all detected pesticides, one was a hormonal disruptor. There were no pesticides in animals, fish and organs in a concentration above the limit of detection (LOD) in observed periods. The concentrations of toxic metals detected in superficial water (Cd, Pb, Hg, As, Mn, Cu) were below the permitted limits, as well as the concentrations of Cd, Pb, Hg, As and Mn in the whole bodies of fish. Concentrations in kidneys and livers of wild animals (rabbit and roe deer) were below the permitted limits, with the exception of cadmium, whose concentrations in some animal samples were above the permitted limit. Based on the obtained results, we concluded that in the developed agricultural region unencumbered by heavy industry, pollution by pesticides and heavy metals can be controlled.
