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.
在格鲁吉亚，没有批准的标准来确定土壤中重金属的最大允许浓度(MPC)的值。考虑到欧盟国家重金属总含量标准化的经验，建议为格鲁吉亚选择MPC，考虑到每种金属的环境危害，根据荷兰生态学家的数据，这是由最大允许添加剂(MPA)决定的。在格鲁吉亚，对于高度危险的Cd，建议使用欧盟使用的MPC的最小值。对于低风险的金属——锌和铅——使用的是欧盟使用的最大MPCs值。对于中度危险的- Cu, Ni -使用欧盟使用的MPC平均值。
