Sažetak
During a period of eleven years (2004-2015), as part of comprehensive monitoring of mercury levels in the vicinity of the natural gas production and treatment plant CPS Molve, biological samples from cows from households in the village of Molve were collected. The samples of milk, blood, urine, faeces, and hair from three cows were taken on ten occasions and analysed for total mercury concentration. Due to the implementation of a new analytical method in 2009, the results are presented separately for the samples collected 2004-2008 (analysed by CV-AAS) and for the samples collected 2010- 2015 (analysed by AMA254). Median mercury concentrations in milk, blood, urine (μg ml-1), faeces (μg g-1 on wet weight basis), and hair (μg g-1) in 2004-2008 monitoring were 0.001, 0.001-0.009, 0.001- 0.002, 0.001-0.041, 0.001-0.049 and in 2010-2015 0.00001-0.0031, 0.00002-0.0002, 0.00002-0.0019, 0.0027-0.0075, 0.0024-0.015, respectively. The highest concentrations of mercury were found in hair and faeces, and the lowest in the blood of tested animals, which corresponds to the toxicokinetics of inorganic mercury after long term exposure to normal ambient air concentrations. Generally, the measured concentrations are very low and below the formerly prescribed maximum permitted concentration of mercury in milk. Also, they do not represent a danger to the health of the people and cows that live in the area potentially contaminated with mercury due to natural gas production.
