4. Conclusions
This study characterized carbonaceous aerosols during the
winter in Masterton, New Zealand. Wood combustion for residential
heating is common during the winter in Masterton and the
results of this study suggest that biomass burning is the dominant
source of PM2.5. PM2.5 was the largest contributor to measured
PM10 concentrations, with an average contribution of 64%.
Carbonaceous species made up 47 and 77% of the PM10 and PM2.5,
respectively. Organic carbon and elemental carbon concentrations
showed excellent correlation with PM2.5 concentrations, suggesting
