English Abstract This report presents tabulated monitoring results from
the National Air Quality Monitoring Network for the Regions 4 (Zuid Holland)
and 5 (Noord Holland) 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.
