ABSTRACT
Monitoring air pollution is an important tool in environmental protection policies as it may reveal where air quality (AQ) should be improved and may determine the effectiveness of control programs. It provides background data useful in order to understand how the pollutants may affect population’s health and the environment, and also to keep communities informed about local AQ. In Romania, measurements for AQ assessment are performed by 142 automated stations that make up the National Network of Air Quality Monitoring (RNMCA). The stations are distributed in all counties being equipped with automatic analysers that should continuously provide data for the ambient concentrations of the main atmospheric pollutants. Present paper aims to evaluate the efficiency of current AQ monitoring system in Romania by analysing non-validated data from the official national site (www.calitateaer.ro) in one year period of catch (2014-2015), for all automatic stations in North East Region, Romania. The background data were evaluated by taking into account their location in relation to the main sources of air pollution, especially in urban environment, but also the consistency of provided data in order to describe their actual impact on population and ecosystems. The results of the assessment converge towards highlighting some major dysfunctionalities of the actual monitoring system: the insufficient number of stations that makes impossible any interpolation of data in order to describe differences in AQ within the city; their placement in areas that are not the most relevant for describing AQ for the city as a whole, as it sometimes depends on the availability of land owned by City Halls; limited data captures caused by the failure of sensors enhanced by lack a strict control and delays in maintenance etc. Therefore there are fewer stations providing less and less data, while, sometimes, there are counties with no data for rather long periods. The final conclusions lead to the necessity to rethink the efficiency of AQ monitoring system, but also the need to correlate the validated data with atmospheric conditions, emissions inventories, and population health studies in order to have an integrated approach that could be used for effective local and regional environmental policies.
