Projektinformationen
The valley of the Mashavera River, about 100 km south of the capital Tbilisi, is an area with very fertile soils of more than 300 km2 in size. Cereals, vegetables and fruits are grown for the conurbations of Eastern Georgia under irrigation due to the aridity of the climate in Eastern Georgia. The river water used for irrigation is polluted with mining waste from a Cu and gold mine in the mountainous region of the middle reaches of the Mashavera River. Furthermore, wastewater from a floatation plant, erosion material from floatation waste deposits, and acid mine drainage has led to high concentrations of dissolved and suspended sulfidic heavy metals (HM). The proposed cooperation project aims at a detailed investigation of the mechanisms and the extent of the transfer of HM from weakly alkaline soils into the food chain. Furthermore, the suitability and effectiveness of a remediation strategy will be tested in field and greenhouse experiments, and the effect of the HM pollution and the remediation on the sensitive habitat function of soils will be evaluated on the basis of microbiological investigations. The project intends to transfer knowledge as well as important impulses for the introduction of environmental standards for soil conservation and food hygiene in Georgia.
