Groundwater Pollution Hazard by Heavy Metals Following the Explosion at an Ammunition Depot near Oštarije, Croatia

Slobodan Miko, Ladislav Palinkaš, Božidar Biondić, Ksenija Namjesnik and Suzana Stiglić


7.1INTRODUCTION

The surroundings of the village of Oštarije, near Ogulin, were struck by an intentional blast from an ammunition depot during the retreat of the Yugoslav army on 13 October 1991. The disastrous explosion of 6000 tonnes of ammunition produced a severe pollution impact on the rural environment within 50 km2. A reconnaissance survey revealed heavy metal contamination of soil and biota, reaching ten times the background values at the explosion site [ 1 , 2 ]. Although the regional contamination may not appear to be catastrophic, except for the highest values of mercury (5.0 µg g−1) and cadmium (12.5 µg g−1), the average heavy metal contents, determined by aqua regia digestion, are in the range of those measured in the area of the Zagreb city limits (cadmium, chromium, lead, mercury, manganese and nickel) [ 3 , 4 ].

The purpose of the current investigation is to determine a possible groundwater pollution hazard due to heavy metal remobilization from the soils at the polluted areas. Soil samples (37) were analyzed further to determine other possible heavy metal contaminants (cobalt, copper and zinc), and the amount and distribution of the bioavailable and exchangeable metallic ions fraction by 1M ammonium acetate extraction. Recent experiments using ammonium acetate leachates on the same samples show, however, a small mobile fraction of copper, lead, manganese and zinc, suggesting that the major part of the pollutants is present as metallic particulate matter, or as weathered resistant oxides, hence the natural recovery of the area is likely to be a long term, gradual process. Mobilization of the metals depends greatly upon the local karst hydrography, as leaching of the contaminated soil is likely to occur through water action.
