Sources of carbon monoxide in air

Why we monitor sources of carbon monoxide

This indicator estimates the proportion of carbon monoxide (CO) in the air coming from industry, motor vehicles and domestic heating in the Waikato Region. In Hamilton and Te Kuiti motor Photograph of people sharing a car journey to workvehicles contribute the highest amounts of CO to the air.

Carbon monoxide (CO) is a poisonous gas that is colourless, odourless and tasteless. It’s absorbed into the bloodstream of people and animals, causing health effects ranging from headaches and dizziness to loss of consciousness and death. Tokoroa, Waihi, Matamata, Putaruru, Ngaruawahia, Te Awamutu and Turangi home heating contribute the most carbon monoxide. In Taupo motor vehicles and domestic heating contribute almost equally to carbon monoxide concentrations.

What's happening?

The main sources of air pollution in the Waikato region are motor vehicles, home heating and industry.

Waikato Regional Council monitors air pollution from motor vehicles, home heating and industry in:

  • Hamilton
  • Tokoroa
  • Taupo
  • Te Kuiti
  • Putaruru
  • Matamata
  • Waihi
  • Te Awamutu
  • Ngaruawahia
  • Turangi

We usually monitor air pollution in winter, as levels of air pollution are usually highest during this season. We estimate where carbon monoxide in air comes from and how much is coming from each of the three main sources. This information helps us to identify potential impacts on air quality in different parts of the region and changes in air quality over time.
