  • GNS Science air particulate matter (APM) research helps improves air quality and health outcomes in New Zealand. We aim to identify where air particulate pollution is coming from, so regional councils can work out ways to stop it. Our science supports better air quality monitoring, management and reduction. Since 1998 GNS Science has analysed over 40,000 air samples collected from monitoring stations across New Zealand and around the world. GNS Science is the New Zealand representative on the International Atomic Energy Agencies (IAEA) Regional Cooperation Agreement air monitoring programme for Australasia and South East Asia.
