Mining activity practiced in Romania for centuries resulted in extended soil polluted areas, having negative effects on the environment and an increased risk for human health. Heavy metal density inside Romplumb Baia Mare was measured to a depth of 100 cm. Spatial distribution of heavy metals in soil layers is extremely varied. In some cases, there has been an excessive concentration of 27770 mg/kg and values 60 times higher than the accepted limit. In 2010 as compared to 2005, experimental results indicate that heavy metal concentration dropped at 0 - 10 cm depth - because this layer consists of filling material; in 2010 compared to 2005, heavy metal concentration increased between 75 - 100 cm depth, because pollutants migrated in time, leading to massive pollution.
