Our research and consultancy aim to identify anthropogenic and natural source contributions that cause air pollution in order to
improve air quality management.

Research and Consultancy Projects

  • Understanding air particulate matter pollution
    This project investigates wintertime air particulate matter (APM) source variations with hourly resolution at multiple sites within an airshed to identify the actual source contributions and particle transport (horizontal and vertical) within airsheds.
  • Air particulate sources and activity inside school classrooms
    Pilot study was undertaken to investigate the air quality in two primary school classrooms (ages 5 –9) over a three-week period, during August 2013. PM10was monitored and sampled (hourly, 24/7) in two classrooms and outside of thePalmerston North School, New Zealand.
  • Arsenic concentration in air
    Air monitoring work by GNS Science has found that atmospheric concentrations of arsenic, a known carcinogen, are above national and international guidelines in a number of New Zealand urban centres.
  • Regional Council airshed studies
    Councils are responsible for monitoring and managing air pollution according to the National Environmental Standards for Air Quality (NES).
  • Road tunnel and roadside studies
    NZTA commissioned GNS Science to monitor and collect air quality samples in a State Highway road tunnel. Traffic emissions were also studied at the Greater Wellington Regional Council air pollution monitoring station beside the Ngauranga motorway in Wellington.
