o:269 A knowledge base as a monitoring system of environmental state in mining operations areas of the cross-border region of Romania and Serbia en ABSTRACT: In our opinion, more open knowledge systems are necessary to inform researchers and population about environmental challenges and to produce societal responses to environmental problems. We have developed a knowledge base to be used as a monitoring system of environmental state in the regions of copper mining operations from the cross-border area of Romania and Serbia. The knowledge base and its content are publicly available. The knowledge base hosts four sections: one section where the specific terms are defined (in English), one section containing information about the state of water, air and soil in the investigated area (in English), the third section enclosing remediation procedures (in English) and the fourth section comprising educational and awareness-building materials that are used in training sessions of youth on the subject of the environmental issues (in both Romanian and Serbian). The knowledge base can be accessed at the following link http://www.elearning-chemistry.ro/rosnet2/knowledge-base/ and a tutorial explaining how to use it is also available.
