The state of NZ's air quality
The Ministry for the
Environment’s latest environmental report shows that air
quality in New Zealand is generally good, but some issues
persist
Released yesterday, the report is a synthesis of data on air quality, pollutants and quality-of-life impacts. Wood and coal burners continue to be a major cause of poor air quality, but the report also highlights gaps in our data, including for PM2.5 and methyl bromide.
GNS Science air particulate specialist Dr Bill Trompetter said the report highlighted that while we spend 80 to 90 per cent of our time indoors, we know little about indoor air quality in New Zealand.
Preliminary results from GNS Science research has supported overseas studies that "outdoor air pollution does indeed find its way indoors," Dr Trompetter said. "Particularly the smaller, more harmful particles from wood fires and vehicle combustion sources."
"At the same time, we have found that air pollution generated indoors, mainly from cooking and household dust, adds to this to generate high particle concentrations that are inhaled indoors. Therefore, individual exposures may be higher than outdoor air monitoring suggests, with a consequent greater impact on our health outcomes.”
The report also touched on light pollution and its impact on wildlife and our ability to view the night sky. Otago Museum director Dr Ian Griffin welcomed the report, which he said provided an important baseline for future measurements of light pollution.
"While it is encouraging to note that, when measured in 2014, 74 per cent by land area of the North Island and 93 per cent by land area of the South Island were minimally impacted by light pollution, as most New Zealanders live in cities, it has been estimated that over half of New Zealanders are unable to see the Milky Way.
"A generation of Kiwis is growing up potentially disconnected from the beauty of night sky."
The SMC gathered expert reaction to the report.

we know at the moment I can’t see any reason for the
current state of play to change."

Top researchers
honoured
Exceptional New Zealand researchers were
acknowledged at Research Honours Aotearoa in Wellington on
Wednesday.
Royal Society Te Apārangi, which hosted
the event, handed out 21 medals and awards and the Health
Research Council presented three awards.
The top award,
the Rutherford Medal, was awarded to Professor Rod Downey
of Victoria University of Wellington for his revolutionary
research into mathematical logic and computer science.
His
work has been applied to efforts as varied as studying
aboriginal children in Australia, reconstructing the "tree
of life", understanding the evolution of European languages,
and even designing better ways to distribute donated food to
charities, the NZ Herald reported.
"There's
this wondrous wholeness of mathematics, that as soon as you
understand something well enough, it leads into other things
and that's what good science is about," he told 1 News.
In addition to the medal, he received a $100,000 prize from the Government.
The Callaghan Medal for science communication was awarded to Dr Helen Taylor from the University of Otago for her work around conservation genetics and threatened species.
One of her
initiatives, ‘The Great Hihi Sperm
Race’, raised more than $11,000 for hihi conservation
and drew supporters from 17 countries, spreading the message
about potential fertility problems for inbred birds.
For
the first time, the Society issued an award for contribution
to Te Ao Māori and indigenous knowledge – named the
Te Puāwaitanga Award, given to
Professor Linda Tuhiwai-Smith of the University of
Waikato.
The Health Research Council of New Zealand also
introduced a new award, Te Tohu Rapuora, for Māori health
excellence and leadership, which was given to the Te Kotahi
Research Institute of the University of
Waikato.
Associate Professor Pitama, of Ngāti Kahungunu and Ngāti Whare, was awarded the Metge Medal for her influence on indigenous health education and Lisa Matisoo-Smith has been awarded the Mason Durie Medal for her research on human migration into the Pacific. Both women are from the University of Otago.
The full list of winners is on the society's website.
