Infiltration of outdoor smoke into homes has become very topical recently, especially when bushfire smoke was blanketing parts of Australia, and public were being advised to stay indoors for some protection. A similar situation occurs in many southern Australian and New Zealand, towns and cities, where outdoor smoke levels frequently exceed air quality guidelines during cold calm winter nights.

Children are particularly vulnerable to the health effects of air pollution and as they spend a large proportion of time at school, this is an important environment for children’s exposure to air pollution. Understanding the factors that influence indoor air quality in schools is critical for the assessment and control of indoor air pollution.

This seminar-style course provided an essential introduction to what air pollution is and what issues are unique to New Zealand. This course explored how air pollution affects the health and wellbeing of people and what factors we can change to reduce the numbers of hospital admissions and deaths due to air pollution.
