Particulate matter from wildlife smoke and asthma related outcomes

09 Oct 2019

This important new study conducted a systematic review of wildfire smoke from all over the world and the association between PM from smoke and presentations to emergency departments for asthma and admissions to hospital for asthma.

The main results were that:

1) Associations were present in all age-groups but increased with age. The group with the greatest size of the association was people over 65 years. For ED presentations it was also possible to evaluate results by sex and there were much clearer associations between fire smoke and asthma presentations for females than there were for males.

(2) The overall size of the associations between smoke-specific PM and asthma presentations and admissions were around 5 times higher than what is generally found in studies of background air pollution from multiple sources, eg in urban environments, and these outcomes.

Study develops LUR models for estimating markers of air pollution

31 Jul 2019

A study involving CAR researchers has developed separate intra-city land use regression (LUR) models for estimating NO2 and NOx, both markers of traffic pollution, for the western half of Sydney, NSW.

Hazelwood: Study identifies long-term effects on infants

25 Jul 2019

A new paper from the Hazelwood Health Study has explored the long-term impacts of the Hazelwood coal mine fire on markers of lung function in young children.  The study, published in Respirology, found a modest association between infant exposure to elevated particulate matter (PM2.5) during the six-week coal mine fire and reduced respiratory system reactance (increased lung stiffness), measured three years after the fire.

Even low-level pollution associated with increased risk of early death

03 Apr 2019

A new CAR study has found that even the low levels of air pollution in Sydney are associated with increased risk of premature mortality. The study is the first in the world to assess a cohort at such low concentrations, and provides further evidence that there is no safe level of air pollution.

Air pollutants linked to increased medication dispensing

11 Feb 2019

A new study from the Hazelwood Heath Study has found that air pollutants from the mine fire are associated with increased dispensing of prescription medications for respiratory, cardiovascular and psychiatric conditions.

Extended database a resource for studying health impacts of biomass smoke

06 Dec 2018

The Biomass Smoke Validated Events Database is a community-driven collection of air pollution events caused by vegetation fires such as bushfires. This latest paper describes how the database has been extended to allow the research community to add to the history of these events. 

Low-level exposure to air pollution linked to hospitalisation for asthma

15 Nov 2018

Long-term exposure to fine particulate matter and nitrogen dioxide, at concentrations well below the current standards, is linked to hospitalisation for asthma, new CAR research has found.

Links between air pollution and diabetes found

15 Oct 2018

The association between air quality and heart and lung diseases is well known, but new CAR research has shown links with blood glucose levels and therefore diabetes.

First national model of particulate matter developed

01 Oct 2018

Our latest paper describes a new method that mapped the concentration of particulate matter at the 2.5 micrometer scale (PM2.5) across large regions of Australia. The method integrates data from two sources: satellites and how land is used (Land Use Regression).

Fish oil may protect against childhood allergies in areas with traffic-related air pollution

27 Aug 2018

CAR researchers studied 400 children in the Childhood Asthma Prevention Study and found that for those living in areas with high traffic-related air pollution, taking fish oil protected them from allergies and poor lung function.
