Impacts of exposure to dust from unsealed roads

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: 1. Characterise the dust and quantify the impacts of dust from unsealed roads on people. 2. Determine the effectiveness and cost of dust mitigation measures. 3. Estimate the costs of the health impacts of dust and estimate the benefits of mitigating the dust. 4. Propose a methodology to support decision making about mitigation options. 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.
