Council’s Environmental Scientist Sarah Brand gave a presentation at the recent Guardians of the Sounds AGM about the Picton Air Quality Study, a joint study by the National Institute of Water and Atmospheric Research (NIWA) and Council, which started in July and finishes in September 2020.
Thirteen air quality monitors and meteorological instruments have been set up to measure Picton’s air pollutants, including nitrogen dioxide, sulphur dioxide and carbon monoxide, as well as air temperature, wind speed and wind direction. NIWA will analyse the data and undertake air flow modelling to better understand the quantity and variability of air pollutants.
Sarah says Picton’s air movement is complex. “The town’s confined coastal, hilly location means its air quality is affected by a wide variety of sources including transport, industry and domestic sources, as well as dust, sea salt and pollen. It’s too early to draw any conclusions yet but we will keep the community informed as we progress.”
