Town Summary
Air quality in this town

Henderson monitoring stations was established in December 1993 and we currently monitor NO2, PM10 and Black Carbon.

Air quality is generally good for most of time. Air pollution sources are mainly from residential home heating (during winter) and vehicle emissions (particularly at busy roadside). The monitored NO2 concentrations meet national environmental standards for air quality. PM10 concentrations usually meet national environmental standards for air quality.

    The table shows the proportions of the main sources of PM in this town from home heating, industrial activities, outdoor burning and traffic.  (Indoor sources and natural sources of air pollutants are not included in this breakdown). 

    These values come from 2013 data sourced from MfE’s data service.  Consistent methodology was used to calculate these estimates of PM emissions, which allows comparison between towns throughout New Zealand.  Some regional council published emissions information might differ if they were prepared in a different year or used another method. Contact your regional council for more information about PM and other emissions.

What is this graph showing me?

The graph shows the monthly average PM concentrations at one representative site in this town for the year selected. In many towns in New Zealand, PM peaks in the winter when air temperatures and wind speeds are lowest as more people heat their homes during colder weather, and still conditions mean that there is no wind to disperse the air pollutants.
