The primary purpose of this research was to improve our understanding of the impacts that dust emissions from unsealed roads have on people and investigate dust mitigation measures. The project’s key research objectives were:
A two month road dust monitoring campaign was undertaken on a section of Mataraua Road, 10km southwest of Kaikohe in the Far North District, during February, March and April 2015.
The monitoring results indicated that potential adverse human health impacts might occur due to the dust discharged from untreated unsealed roads. A comparison of the PM10 concentrations monitored at the untreated and treated sites showed that the application of a dust suppressant significantly reduced the impact of dust discharged from the road.
Keywords: dust PM10, dust suppression, health effects, unsealed roads.
In the original version of the report, Golder had incorrectly presented the health costs calculated for the Kiakohe CAU rather than the Ngapuhi-Kaikou CAU within which Mataraua Road is located. A review by Emission Impossible Ltd highlighted the issue and enabled Golder to amend the report. We acknowledge this error and appreciate the opportunity to correct it.
Incorporating the correct health cost calculations into the report has resulted in a slight change to the conclusions. The BCR values have changed (improved) as follows:
