FACTS National annual sulphur dioxide concentrations fell by 38% between 2004 and 2007. Particulate matter concentrations exceeded EU daily limit values in certain locations in 2007, with peak concentrations in March and October 2007 corresponding with weather events when Sahara dust was being transported to Malta.National annual average nitrogen dioxide concentrations were well below the EU annual limit value in 2007 but exceeded the limit value in 27 localities.Ozone concentrations exceeded EU standards in certain rural areas in 2007. The majority of Malta’s ozone is of transboundary origin.Sub-reportAir Sub-reportIndicatorsA1 Particulate matter concentrationsA2 Ozone concentrationsA3 Concentrations of Benzene and other volatile organic compoundsA4 Nitrogen dioxide concentrations A5 Sulphur dioxide concentrationsDatasheetsParticulate matter concentrationsAnnual average concentrations of major air pollutants MapsAnnual average ozone concentrationsAnnual average benzene concentrations Annual average nitrogen oxides concentrationsAnnual average sulphur dioxide concentrations Background documents & LinksFor additional information click here.Interim Report on the Preliminary Assessment of Arsenic, Cadmium, Mercury, Nickel and Polycyclic Aromatic Hydrocarbons in Ambient Air in MaltaReporting of National Programmes under the National Emission Ceilings Directive (2001/81/EC)
