"The project ORCHESTRA has the main aim to disseminate and exploit the European research activities dealing with computer models for the environment. These models have a huge potentiality for dissemination, for their nature, based on information technologies. This area is multidisciplinary, because it deals with environmental science, health, chemistry and information technology. The general impact of information technology is proceeding in an exponential way. Specific use is often limited by a poor knowledge about the availability of suitable tools, cultural scepticism, and lack of training. We will address the strategies for a broad, systematic dissemination and exploitation of the research results of a number of EU projects. Specific dissemination and exploitation measures will be identified for the different stakeholders, including regulators, industry, citizens, international bodies, scientific and other associations. Dissemination towards regulators of all EU member and associated states will be provided. We will also address industry, with special attention to SME, which may gain from the software we are dealing with. We will communicate to citizens, their associations, scientists and other publics with different tools. In the consortium we have representatives of all major stakeholders involved, and a number of partners expert in efficient communication strategies. A sustainable strategy will result from the project. The software products from the different projects will be organised in a web-based system open to the public for continuous access and promotion. Links with other initiatives will exploit results at the regulatory level and in the information technology community, making results living and evolving. The mathematic approach we will disseminate will be also useful to generate simple indicators of regulation impact. ORCHESTRA will promote a repository of software and databases, suitable for updated information on European research on chemicals."
