The ultimate goal of the research is to determine the efficacy of non-proprietary products in reducing road dust pollution on gravel roads in Nepal, in terms of social and economic impacts. The project made a literature study of the recent history of dust on roads, identified a number of potential suppressants and procured appropriate equipment for measuring dust. This report summarises the equipment trials and proposes a methodology and research matrix for a future phase of the project, where the effectiveness of suppressants will be measured and the potential effects of dust on rural communities will be assessed.
