Statistics

stat-4.jpgThe air quality in Cyprus is in general quite good; yet there are still episodes of high air pollution in inhabited areas each year. The government and national authorities are working hard to improve the situation.

During 2006 a complete new set of air quality management and information tools started to operate in Cyprus, accompanied by 4 new air quality monitoring stations. With the aid of these new tools and by making use of the data that were being added to the ones being made available to the past, better statistics and assessments are expected to enrich and suport air quality surveillance, management and thus improvement.

 


There are three site categories in Cyprus cities where the traffic caused pollutants NO2 and Benzene reach average concentration values higher than the Upper Assessment Threshold and even higher than the future EU limit values.

  • These site categories are city areas with high traffic load, e.g. Makarious Avenue in Nicosia. 
  • Bad ventilated inner city areas (urban background and commercial places, e.g. Municipality market in Larnaca). 
  • The most serious problems exists if both categories occur together: Bad ventilated high traffic areas. 
  • Ozone has higher values in high elevated background areas like in Troodos mountains. This ozone is an overall transboundary problem. 
  • In the cities the ozone concentrations are lower than in the background because of the depletion by the primary emitted pollutants there

Examples of model results of effected areas:

NO2-winter-300.jpg During winter an increased NO2 level in and around the cities can be seen. Rather high concentrations occur in Nicosia due to stable atmospheric conditions including inversion layers, that are characteristic for the cold season
SO2-summer-300.jpg The most important SO2 sources are the power plants of Kyrenia at the north coast and Vassilikos, Moni and Dhekelia at the south coast. All of them cause average concentration values in their close vicinity of 8 to 12 µg/m³ (yellow), respectively up to 20 µg/m³ (orange) in the case of the power plants of Moni and Vassilikos.
Benzene-300.jpg The map presents the mean annual interpolated Benzene concentration distribution over Cyprus is shown. Similar to the case of NO2, the highest concentrations are expected in the cities, where major emission sources are located, including the transportation sector.
03-300.jpg The map shows the intrapolated Ozone distribution during summer. As can bee seen ozone is a typical high in rural elevated areas and low in urban areas.
