Abstract

This report presents tabulated monitoring results from the National Air Quality Monitoring Network for the city stations and street stations in all regions for the calendar year 1992, the summer of 1992, the winter of 1991-1992 and the period 1 April 1991 - 31 March 1992 (tropical year: EC reference period) ; SO2, black smoke (= suspended matter measured by the black smoke method), fine dust (PM10), NO2, NO, NOx (=NO2+NO), O3, Ox (=NO2+O3) and CO are the components concerned. This year for the first time results of measurements of PM10 are presented. Since the monitoring of this component at most stations started in the first months of 1992, no statistics are calculated for the periods 'winter' and 'year April/March'. Furthermore, for every station in the network it was checked whether Dutch limit values were exceeded. Nationally exceedances of the limit values for black smoke, PM10 and NO2 were observed. The draft limit value for O3 was not exceeded.
