Sažetak
In the last two decades (1990-2012), as part of a comprehensive monitoring of the eco-system, earthworms were collected from four locations in the vicinity of the natural gas production and treatment plant Molve, Croatia. Their tissues were analyzed for total mercury concentration by cold vapour AAS. The range of the median mercury concentration values (wet weight) in earthworms were 0.004-0.283, 0.013-0.260, 0.005-0.317 and 0.009-0.191 μg/g for Molve 9, Molve 10, Molve 11 and Molve 12 location, respectively. Although the results of mercury measurements in earthworm tissues from different locations vary in a wide range of values, integrated results of all measurements during last twenty years period demonstrate small but constant decline in concentration values, especially after the year 2004. Comparing our results with results published in available data from Europe and some areas of Croatian on mercury concentration in earthworms it can be concluded that area investigated in this research belongs to moderately mercury contaminated region. Nevertheless, further eco-monitoring and mercury measurements in various biological samples are important for more complete interpretation of results and will be continued.
