The ability to predict the behaviour of pollutants in the environment in different contexts (calamities, accidental pollution) and time periods (hours, years) can bring great benefits to society and the economy. Pollutant monitoring programs running at international level aim at assessing their level in air, water and soil. At European level, precise and sufficiently comprehensive information on the distribution of many pollutants is collected and stored. Unfortunately, Romania’s contribution to the achievement of the European Atlas presenting the synoptic picture of the concentration of pollutants in the environment throughout Europe is almost insignificant, unsystematic and arrhythmic. This action is vital to the efforts of the European nations, which is also underlined in the Paris 2015 United Nations Framework Convention on Climate Change Conference. Trustworthy, objective and highly reliable data at European level should be provided to the local, national and European community in terms of the identified and quantified species. This will allow responsible actors to take appropriate action and to ensure that the population is correctly and in time informed on the real state of the environment. The enormous diversity of pollutants in all compartments of the environment makes their identification, quantification and control as complex and diverse as their huge number. The CERNESIM Centre, through its facilities, in a unique assembly at national and Eastern European level, can provide new data on the distribution of pollutants characteristic for the north-eastern region of Romania. CERNESIM can help increase the quality of environmental research. The newly created laboratories provide researchers suitable tools to carry out analyses, studies and simulations on environmental issues such as pollution levels, to investigate the applicability of clean technologies, investments and environmental projects, and the economic modelling of environmental processes.
