Government Decision No. N 1142-N validating the Procedure for air quality assessment criteria, pollution measurement methods and standardized measurement methods, as well as unified criteria for the locations and quantities of pollution measurement stations.

This Government Decision focuses on establishing standardized methods and criteria for assessing air quality and pollution levels. It aims to define uniform standards for measuring air pollutants, including particulate matter, gases, and toxic substances, with the overarching policy goal of environmental protection and public health safeguarding. The resolution explicitly sets out principles for evaluating air quality concerning human health and ecological impacts, emphasizing the importance of scientific basis and international standards. Key measures include the approval of specific air quality assessment criteria, measurement methods, and the placement and quantity of pollution monitoring stations. It details the permissible and target concentration levels for various pollutants, such as SO2, NO2, PM10, PM2.5, benzene, CO, and toxic metals, along with their respective averaging periods and exceedance thresholds. The document prescribes the use of stationary, indicative, and modeling measurement techniques, with specific standards for sampling and analysis, and stipulates minimum requirements for monitoring station locations based on population density and emission sources. It also delineates the minimum number of monitoring sites required for different regions and pollutants. The document further addresses procedural aspects, including the organization of monitoring activities, responsibilities of relevant institutions, and the necessity of compliance with international standards. It specifies the minimum number of sampling points for various pollutants, the criteria for station placement, and the timelines for establishing monitoring networks. Secondary themes include the enforcement of measurement procedures, stakeholder involvement, and the integration of modeling techniques to supplement physical measurements, all aimed at ensuring effective air quality management in accordance with the outlined standards and timelines.
