Meetactiviteiten in 1996 in het kader van het Landelijk Meetnet Luchtkwaliteit

The Dutch National Air Quality Monitoring Network is one of the responsibilities of the Laboratory for Air Research of the National Institute of Public Health and the Environment. The main objectives of the air quality network are to monitor ambient air quality, supervise implementation of air quality standards, alert authorities and the public to pollution episodes, provide validation of model results, support diagnosis using model simulation, support short-term model prognosis and assist in quantifying atmospheric deposition. As part of the information on the monitoring network an annual report is published in which surveys of the monitoring stations per component are provided, along with maps of their locations and information on the measurement methods. The measurement programme is established annually in consultation with the Air Directorate of the Ministry of Housing, Physical Planning and Environment. The programme for 1996 includes the gaseous components ammonia, carbon monoxide, ozone, nitrogen oxides, sulphur dioxide, Volatile Organic Components, Very Volatile Organic Components and fluorides. Further elements in the programme are particulate matter like heavy metals (arsenic, cadmium, lead, zinc), acidifying components (ammonium, chloride, nitrate, sulphate), black smoke and PM10, as well as the chemical composition of precipitation (acidifying components, heavy metals, mercury, lindane and a supplementary set of pesticides).
