Air Pollution Management

In today’s world, where the continuity of information gains more importance, The Ministry of Environment and Urbanization has established an Air Pollution Emission Management System (HEY) in 2017 through the TÜBİTAK Public Institutions Research and Development Projects Support Program (KAMAG) and the system is served by the Ministry via its server.

With the HEY System, it is aimed to carry out the monitoring process and controlling of the formation, spread of air pollutants within a certain national systematic framework.

Data are acquired from polluting sources, emission amounts are calculated, and emissions are determined with a temporal and spatial resolution of 1km*1km, using the “Air Emission Management Portal”. Therefore, street-level air quality maps are obtained in our cities.

With the “Air Emission Management Portal”; By obtaining data from polluting sources and calculating the emission amounts, the emissions are determined with the temporal and spatial resolution of 1km*1km. Thus, street-level air quality maps can be obtained in our cities.

The National Air Pollution Emission Management System provides the following:

  • classification of the main sources of air pollution,
  • combining source information in detail,
  • processing this information with the support of geographic information system,
  • making inventory calculations of air pollutant emissions,
  • distribution of emission totals by air quality models, and
  • monitoring all these relationships on spatial maps by making data entries on the web

The purpose of the AQI is to help us understand the link between our health and the air quality of the region we live in.

If the AQI value is 100, it usually corresponds to the national air quality standard. An index value below 100 generally indicates a good situation. The higher the AQI is, the higher the air pollution is and the higher the risk to public health risk. An AQI value over 300 indicates that the air quality is poor and, consequently, the risks to human health are high.

When AQI falls in the following range Symbolised by the following colors
Between 0-50 Good Green
Air quality is considered satisfactory, air pollution is low and poses little or no health risk.
Between 51-100 Moderate Yellow
Air quality is acceptable, but for some pollutants, there may be a moderate health concern for a small number of people. For example, some respiratory symptoms may be observed in individuals who are very sensitive to ozone pollutants.
Between 101-150 Unhealthy for sensitive groups Orange
Members of sensitive groups are particularly vulnerable to certain pollutants. This group is more likely to be affected, even at these lower levels, than the general public. For example, people with respiratory diseases will be exposed to higher risks due to their exposure to ozone pollutants; people with heart disease, for instance, will be at a higher risk due to their exposure to particulate pollutants in the air. The general public, however, is not likely to be affected by an AQI in this range.
Between 151-200 Unhealthy Red
Everyone may begin to experience health effects. Members of sensitive groups may experience more serious health effects.
Between 201-300 Very unhealthy Purple / Pink
It is a trigger point for the health alarm. Everyone is at risk of more serious health effects.
Between 301-500 Hazardous Brown
It is a trigger point for emergency health warnings. All segments of society will most likely be affected.
