Mercury in hares (Lepus europaeus Pallas) collected around gas treatment plant

For the last eighteen years (1990-2007), as part of a comprehensive monitoring of the eco-system, hares (n=5) were collected around natural gas processing plant – GTP Molve on eight occasions. Their organs (muscle, liver, kidney and brain) were analyzed for total mercury concentration by cold vapor AAS. The range of the median mercury concentration values (wet weight) in hares organs were 0.001-0.005, 0.010-0.045, 0.020, 0.130 and 0.001-0.015 µ ; g/g for muscle, liver, kidney and brain, respectively. Comparing our results with results published in available literature on mercury concentration in hares it can be concluded that area investigated in this research belongs to low contaminated region by mercury. Achieved results also point to the fact that closed mercury removal system installed in 1993 is effective in mercury removal from natural gas.
