Israel’s Air Monitoring Network EEA visit – 5 July 2011 Dr. Levana Kordova Air Quality & Climate Change Division Ministry of Environmental Protection
Objectives of the National Air Quality Monitoring Network • to characterize air quality in Israel • to inform the public and publish alerts when necessary • to identify the major pollution sources • to analyze air pollution episodes • to develop a national database for: • long-term policy planning • formulation of standards and legislation • environmental research
The National Air Monitoring Network • early 1970s – first monitoring stations near power plants in Tel Aviv and Ashdod • 1994 - MoE initiated a plan to develop a wider national network and a national control center • 2002 – completion of the national network & control center • 2011 – a total of 140 stations • Stations operated by MoE: 26 stationary & 2 mobile • Additional stations operated by municipalities & large industries, under MoE quality control ; ISO standards for uniform operation& maintenance
Air Quality Monitoring Station Sampling system – Manifold (Jerusalem, “Safra” station) Meteorological mast
General Monitoring Station • Representative locations, usually not adjacent to specific sources • Many stations in open urban areas, at roof height, on schools or public buildings • Monitored pollutants: SO2, NOx, O3, CO, PM • Meteorological parameters recorded: wind speed, wind direction, air temperature, humidity, solar radiation, precipitation
Transportation Monitoring Station • Located near primary traffic junctions, at ground level. • Monitored pollutants are those originating from traffic: NOx, CO, PM, BTEX, Butadiene (1,3) • Total of 11 stations

Annual PM2.5 Data for 2010 Annual Target Standard: 10 μgr/m3 (WHO Guidelines)
Annual PM10 Data (2008) The annual concentration of particles ranges between 50-55 micrograms per cubic meter. In the Beersheba region in the south of the country, particle concentrations range between 55-60 micrograms per cubic meter.
ANNUAL AVERAGE OF NITROGEN OXIDES CONCENTRATION (2008) MAXIMUM HALF-HOUR NITROGEN OXIDES CONCENTRATION (2008) Half – hour standard 500 ppb
MAXIMUM EIGHT-HOUR OZONE CONCENTRATION (2008) Eight-hour standard 82 ppb ANNUAL AVERAGE OF OZONE CONCENTRATION (2008)
Publications (clean air website) • On-line map of air quality parameters • Air quality index, twice a day • Air quality forecast, on a daily basis • Detailed data tables for each station • Monthly and Annual reports
