Influence of waste dump remediation on the levels of mercury in the air.

Mercury concentrations in air were measured at three measuring sites in the vicinity of a waste dump Jakusevec in Zagreb, Croatia over a 4-year period, from the beginning to the end of remediation. Measurements at the beginning of the remediation show that the concentrations of mercury at all three measuring sites were relatively high. Annual mercury mass concentrations in 2001 were between 17 and 445 ng m(-3). Annual mercury averages in 2004 ranged from 8 to 10 ng m(-3). Mercury variations were analysed with regard to the meteorological conditions. The results of this investigation show that in regard to mercury, the remediation was successful.
