The main air contaminant of concern in Taupō is PM10 (particles in the air less than 10 microns in diameter).
Concentrations of PM10 have exceeded the National Environmental Standard (NES) limit of 50 μg/m3 at the Taupō monitoring site since monitoring commenced in November 2000. However a decrease in concentrations has been observed in more recent years, and it now appears that the site may be close to NES compliance.
A previous emission inventory for Taupō was carried out in 2009. This report assesses changes in PM10 emissions in Taupō since 2009, and compares them with the observed reduction in concentrations. The report primarily focuses on emissions from domestic heating, motor vehicles, industrial and commercial activities and outdoor burning. It also looks at carbon monoxide, nitrogen oxides, sulphur oxides volatile organic compounds, carbon dioxide, benzene and benzo(a)pyrene.
