Tokoroa

Tokoroa is midway between Hamilton and Taupō on State Highway One. It has one monitoring site, on Billah Street.

Tokoroa’s one active residential PM₁₀ monitoring station, at the Billah Street Reserve, was established in March 2001. PM₁₀ is measured using an FH 62 BAM along with collection of meteorological data. PM_2.5 is measured using a BAM 5014i. The PM₁₀ data is gravimetrically adjusted based on co-located sequential partisol monitoring.

The table shows the proportions of the main sources of PM₁₀ 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 PM₁₀ 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 PM₁₀ and other emissions.

What is this graph showing me?

The graph shows the monthly average PM₁₀ concentration at one representative site in this town for the year selected. In many towns in New Zealand, PM₁₀ 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.
