Health Impacts Of Exposure To Human-made Air Pollution

Emerging evidence shows that exposure to two
human-made air pollutants is associated with significant
health impacts, Stats NZ said today.

The indicator Human
health impacts of PM2.5 and NO2 reports on the health
impacts associated with exposure to PM2.5 (fine particulate
matter less than 2.5 micrometres in diameter) and NO2
(nitrogen dioxide) from human-made air pollution. It
supersedes the previous health impacts indicator, Health
impacts of PM10.

The new indicator:

• focuses
  on PM2.5 (particulate matter 2.5) and NO2 (nitrogen
  dioxide), the air pollutants now known to be of most concern
  in Aotearoa New Zealand
• expands the list of health
  impacts to cover estimated childhood asthma prevalence and
  hospitalisations associated with exposure to human-made NO2
  air pollution
• shows the proportion of Aotearoa New
  Zealand’s population living in areas with poor air quality
  (based on exposure to concentrations of air pollutants above
  the World
  Health Organization (WHO) 2021 global
  guidelines)
• presents health impact data at the
  territorial authority and national
  levels.
