About rationing of the heavy metals in soils of Georgia

Abstract

Abstract In Georgia, there are no approved standards that determine the values of Maximum permissible Concentrations (MPC) for heavy metals in soils. Taking into account the experience of normalizing the gross content of heavy metals in the EU countries, it is proposed to select the MPC's for Georgia, taking into account the environmental hazards of each of the metals, which is determined by the maximum permissible additives (MPA), according to the data of Dutch ecologists. In Georgia, for the highly dangerous Cd, it is proposed to use the minimum value of the MPC used in the EU. For low-risk metals - Zn and Pb – is used the maximum values of MPCs used in the EU. For moderately hazardous - Cu, Ni – is used the average value of the MPC used in the EU.
