暂无分享,去创建一个
A new technique to sample dust on road surfaces is presented. It is based on the use of water to wash a road surface, hence the name wet dust sampler (WDS). The sample water is collected allowing for a range of analyses. The WDS is a prototype, and this technical note describes the development of the equipment, problems encountered, performance and repeatability, and suggested areas of use.
