| Project Summary | |
| The objective of this research is to develop and apply methods to better constrain the magnitude and the chemical nature of metals on particulates in natural settings. This is to be accomplished through in situ measurements of particulates in natural settings across Canada to determine the elemental chemical composition as a function of particulate size and through the development of micrometeorological techniques for flux measurements of aeolian dust. The equipment and experimental methods have been field-tested and modified as necessary. PIXE cascade impactor collections successfully showed that there were emissions of metal-bearing particulates from a remote site containing the same metals in the substrate. Total suspended particulate flux measurements revealed that hi-vol cascade impactors should be used in future studies in order to obtain enough particulates at various heights to determine the total particulate flux as well as the size-fractionated flux | |
