Air quality monitoring report for Hamilton, Tokoroa, Taupo, Te Kuiti, Putaruru, Matamata, Ngaruawahia and Turangi – 2012

Report: TR 2013/33

Abstract

Air quality monitoring in the Waikato region focuses primarily on concentrations of PM10, the main air contaminant of concern. The National Environmental Standards for Air Quality (NESAQ) has set a maximum concentration limit for PM10 of 50 μg/m3 when averaged over 24 hours (referred to as an ambient air quality standard). The NESAQ allows for one exceedance of this standard per rolling 12 month period. More than one exceedance within a rolling 12 month period is a breach of the standard. The NESAQ requires air quality monitoring to take place in areas that are likely to exceed the standard for PM10.
