KEY FACTS

  • National annual average sulphur dioxide concentrations decreased by 5.8% in 2010 remaining well below the EU critical level.
  • Average annual benzene concentrations declined by 32.8% between 2008 and 2010, and no locality average exceeded the EU limit value.
  • Malta experienced higher levels of particulate matter in 2010, and EU standards were exceeded in Msida, which is the site most dominated by traffic.
  • Annual average nitrogen dioxide concentrations decreased from 28.1µg/m3 to 26.3µg/m3, remaining well below the EU and WHO limit value in 2010, however 18 out of 131 individual sites measured registered levels higher than the limit value.
  • Annual average ozone concentrations increased marginally from 102.8µg/m3 to 102.9µg/m3 in 2010. The 8-hour limit value was exceeded in Għarb and Żejtun, but not in Msida. Ozone in Malta comes mainly from transboundary sources.
