Description: Das Projekt "Weltweite Sanierung von Quecksilber-Schäden mit Hilfe der Biotechnologie" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum für Infektionsforschung GmbH durchgeführt. Mercury is a priority pollutant because of its extreme toxicity, global atmospheric transport and accumulation in the food chain. Removal of mercury from current industrial emissions as well as from previously polluted sites is therefore mandatory and should take into account the latest achievements in science and technology. A unique biotechnological process for removal of mercury from wastewater based an the enzymatic transformation reactions of live mercury resistant bacteria has been developed and operated in full industrial scale at a Czech chloralkali electrolysis factory. Another recent achievement are specially coated voltammetric electodes able to detect femtomolar amounts of mercury in a quick and simple way. These new technologies are environmentally friendly and cost effective and have a much broader potential than that realized to date, which, however, needs to be assessed carefully an a case by case basis for each new application. In the case of microbes, fundamental barriers of understanding and acceptance also must be overcome in order to promote their application. For full scale remediation, microbiological technologies have to be integrated into a complete process remediation scheme which also includes physical and chemical technologies, pre-treatment steps and waste disposal strategies. The aim of the specific support action BIOMERCURY therefore is - 1. to evaluate the applicability of the new, microbe based technology, for clean-up of contaminated air, wastewater, groundwater, soil, solid waste from past industrial operations (e.g. electrolysis factory buildings), contaminated rivers, lakes, swamps, coastal areas, and gold and mercury mines, and mine tailings - 2. to monitor the Operation of the first industrial microbe based mercury removal plant, and to collect data an longterm performance - 3. to compare costs, safety and efficiency of the new biotechnological approach to traditional methods - 4. to transfer knowledge an the new biotechnological approach into countries were the problems are most urgent, e.g. Eastern and Southern Europe, Asia, South America and Africa - 5. to coordinate activities and to exchange information with US agencies currently actively involved in implementing new control technologies, e.g. for coal fired power plants 6. to communicate relevant information to governments, decision makers and international agencies. These goals shall be approached by an international consortium which will first conduct case studies an hot spots of pollution as well as an current mercury emitting industries. On this basis, integrated engineering concepts will be developed in cooperation with partners in affected countries. They will be communicated to Governments and International Agencies with the aim of implementing demonstrations or full scale remediations. Research deficits will be identified in the process and will lead to new R and D projects within the European Community.
