Abstract

In New Zealand the main air contaminant of concern in urban areas is PM10. 

In the Waikato, concentrations of PM10 breach the National Environmental Standard ( 50 μg m-3 – 24-hour average with one allowable exceedence per year) in Tokoroa.  The areas of Hamilton, Putaruru, Taupo and Te Kuiti are all marginal with respect to NES compliance, with each of these areas recording one exceedence of 50 μg m-3 in 2011.

This report primarily focuses on emissions of particles (PM10) from domestic heating, motor vehicles, industrial and commercial activities and outdoor burning. Other contaminants included in this emission inventory are carbon monoxide, nitrogen oxides, sulphur oxides volatile organic compounds, carbon dioxide, benzene and benzo(a)pyrene.

Previous emission inventories in 2001 and 2005 for Hamilton have been conducted and in 2004 and 2007 for Tokoroa.
