The below stated work scrutinizes ecological risks that are related to mining and metallurgical industries. It analyzes problems caused by pollution of air, soil and water and suggests new possible ways of resolving those problems. Namely, such innovative and energy-efficient technologies are argued as phytoremediation and exothermic self-propagating high-temperature synthesis of solid-phase recovery of metals (SHS). Visual arguments in support of the efficiency of the selected methods are provided.

Environmental pollution increases from year to year and concentrations of pollutants reach a colossal point, which ultimately affects the health of the living organisms. Industrial pollution and old mining methods are one of the sources of harmful agents in the environment. It is important to study and monitor environmental pollution in dynamics. During several years we have been researching heavy metals distribution in soils in the South East part of Georgia. “RMG Gold and Copper” mine in Kazreti is one of the biggest enterprises in Georgia. As a result of open-cast mining aerosols containing heavy metals are ejected which causes harmful effects of the environment. Within this research 21 villages in Bolnisi and Dmanisi municipalities were investigated;analysis of agricultural soils showed that the concentration of cadmium in the vicinity of the enterprise was significantly increased and exceeded maximum allowed concentrations. Through the wind, cadmium-containing dust spreads out to the 22

The Zemo Imereti (Chiatura) Structural Plateau covers the easternmost part of the western Georgia limestone belt and is the only region of the platform karst in the entire Caucasus. Zemo Imereti Plateau’s complex structural studies revealed that the karst landscape has been completely transformed due to human strong economic activities, mainly related to the manganese unplanned, predatory extraction. The ore mining process completely destroyed the soil and vegetation cover thus creating “anthropo-badlands”. Due to manganese open-cast mining, the layers located over limestones are almost totally removed and heavy rains stipulate intense washout of substances from loose rocks. Intense washout of manganese extracted from mines and high contamination of river water streams take place directly in the river beds. Karst sinkholes and wells are common in the plateau, which are often used as waste fills-storages by the local population. Contaminated underground karst waters flowing into the above mentioned landforms are directly related to the karst springs used by the population and occasionally cause their turbidity and contamination, which is also confirmed by our indicator tests. As a laboratory study of the samples showed, mineralization of underground karst waters in the study area is 1.5 - 3 times higher than similar values in neighboring karst areas, which should be explained by the widespread of manganese open pits in the feeding basins of underground karst waters. According to the materials obtained from our surveys and calculations carried out, karst (chemical) denudation (surface 64.2 - 190.6 m3/km2/year, underground 1.5 - 117.0 m3/km2/year) has been increased in the study area than in other karst regions of Georgia, which is also related to technologic factors.

Karst groundwater is the major natural resource of drinking water for many countries in the world. Especially in karstic regions, karst water requirements for settlements are provided from karst aquifers. Also, we should consider, that karst groundwater is becoming more and more valuable for drinking water supply. Thus, karst groundwater quality and permanent ecological monitoring are very important for populations. Moreover, if we consider that the karst landscape is the extremely sensitive system towards anthropogenic activities, since exaclty the anthropogenic activities largely identify the karst water pollution-turbidity causing factors. This paper presents a new study regarding the quality of the karst groundwater of the study area, which contains important resource of drinking water. In the mentioned study, 12 water samples were collected from different locations of the 4 main karst springs (Krikhula, Dolabistavi, Kidobana and Sakishore) during the spring and summer of 2014 and 2015 years. The main aim was to identify chemical compositions (Ni, Ag, Co, Cd, Zn, Pb, Al, Mg, Fe, F, Cu), and also, it was important to detect Escherichia coli (E. coli). Our research regarding all these chemical compositions shows that all the values are low and under the environmental limit according to the Georgian standards. We measured chemical parameters of all these samples by Atomic Absorption Spectroscopy (AAS) in the chemical laboratory of Ivane Javakhishvili Tbilisi State University, country of Georgia.
