Abstracts: ISEE 22nd Annual Conference, Seoul, Korea, 28 August–1 September 2010: Outdoor Air Pollution From Residential Wood Combustion and Associated Health Effects
A Geographical Approach to Assessing the Contribution of Domestic Woodsmoke PM10 to Respiratory and Cardiovascular Mortality
Parts of New Zealand have significant air pollution problems, specifically particulate matter, with which health effects have been associated. The highest pollution levels are found in areas where woodsmoke from domestic home heating is the main source.
In this research, we used regression-based estimates of particulate matter (PM10) at census area unit level sub-divided by sources of emissions (domestic, vehicle, industry, and background). We divided these into quartiles and compared mortality rates for respiratory and cardiovascular diseases for these quartiles, controlling for age, gender, socioeconomic status, and ethnicity. Then, the mortality rates for different source components were compared to see what impact these have on mortality rates.
Respiratory and cardiovascular mortalities show different associations with the air pollution estimates. This suggests that the source of PM10 is important in understanding the nature of the health effects.
This study has used pollution data subdivided into the relevant emissions sources and has found that the contribution of different emissions sources may result in different dose-response health effects.© 2011 Lippincott Williams & Wilkins, Inc.
