Monitoring of PM10 in New Zealand
This report provides a summary of the results of air quality monitoring
of fine particules (PM10 - particles less than 10 micron
in diameter) in New Zealand from 1988 to 2001. Historical measurements
of total suspended particles (TSP) over the period 1964 - 2000 (Auckland)
and 1983 - 2001 (Hamilton) are also presented to analyse trends.
The resports highlights that PM10 concentrations frequently
breach the Ministry for the Environment's ambient air quality guideline
value of 50 µg/m3 (24 hour average) in many areas, both rural
and urban. Note: The graphs and images in this document
are best printed out in colour.
