3.1 Data description | |
The data provide users with information on pollutant emissions (nitrogen oxides, sulfur dioxide, ammonia, non-methane volatile organic compounds, carbon monoxide, particulate matters PM10, fine particulate matters PM2,5) by type of economic activity per calendar year. Furthermore, the data on emissions of major pollutants (solid emissions, nitrogen oxide, sulfur dioxide, carbon monoxide) from stationary sources by regions and districts per year, as well as specific territorial emissions. |

3.4 Statistical concepts and definitions | |
The pollutant is any substance present in the air or introduced into the air that has or may have harmful effects on human health or the environment as a whole. Emission means the release of a pollutant from a point source or diffuse source into the air. Emissions of air pollutants are classified according to their origin into natural (forest fires, volcano eruptions) and anthropogenic (related to human activities). Anthropogenic pollutant emissions are released into the atmosphere from stationary point sources (heat and electricity generation, domestic heating, industrial combustion and technological processes, fossil fuel extraction and waste incineration), areal or fugitive sources and mobile sources (transport). The main pollutants are: particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOC), ammonia (NH3) and carbon monoxide (CO).

10.7 Quality documentation | |
SO SR internal documentation to ensure the quality of statistical outputs: - Methodological guideline for applying mathematical-statistical methods for the statistical survey - Methodological Instruction - Quality Indicators of Statistical Outputs and Statistical Processes - Code of Practice for European Statistics: https://slovak.statistics.sk/wps/portal/ext/aboutus/key.documents/code.of.practise
|
11 Quality managementUp | |
---|---|
11.1 Quality assurance | |
The SO SR has a quality management system in place. The Quality Manual includes a description of the quality management system and the fulfillment of ISO 9001 requirements. The application of the Manual ensures that all activities that affect the quality of the products being produced are planned, managed, reviewed, evaluated and meet the requirements accepted in the order. The Quality Guide is available at: The basis of the whole quality management system is the Code of Practice for European Statistics: https://slovak.statistics.sk/wps/portal/ext/aboutus/key.documents/code.of.practise
