Synopsis

This report presents the tabulated results of the regional stations of the National Air Quality Monitoring Network in the regions 4 (Zuid-Holland) and 5 (Noord-Holland) for the calendar year 1998, summer 1998, winter 1997-1998 and 1 April 1997 - 31 March 1998 (tropical year: EU reference period). The components measured were: NH3, fine dust (PM10), CO, oxidant (Ox , which is NO2+O3), O3, NO2, NO, NOx (=NO2+NO), black smoke (which is suspended matter measured by the black smoke method) and SO2. The fine dust (PM10) measurement data are multiplied by a factor 1.33 to correct the systematic underestimation when compared to the EU reference method for PM10.
