The article “Mobility of Heavy Metals Originating from Bombing of Industrial Sites” reports measurements of heavy metal concentrations at several industrial sites in June1999,just after the bombing, and again in March of2000.At the Smederevo site, on the banks of the Danube River, eight soil specimens taken in 1999 had an average lead concentration (in mg/kg) of 10.7 with a standard deviation of 3.3. Four specimens taken in 2000 had an average lead concentration of 33.8 with a standard deviation of 0.50.
