This is an investigation of the trace constituents in arctic aerosols,          using the Instrumental Neutron Activation Analysis (INAA) technique.            The technique is extremely sensitive and powerful, capable of                   determining the concentration of about forty elements, including many           environmentally crucial ones such as aluminum, zinc, arsenic and                antimony that are present in very low concentrations.  The project will         make use of 700 filtered samples obtained on Ellesmere Island over an           eight-year period.                                                                                                                                              The occurence of arctic haze, the general term for aerosol                      concentrations in the lower troposphere, reaches a seasonal maximum in          late winter when it becomes widespread through the arctic.  The                 variation is the result both of seasonal differences in the northward           transport, and in the removal process through wet and dry deposition.           Multivariate factor analysis, cluster analysis, and source contribution         functions, combined with air mass trajectories will provide advective           patterns that will refine our understanding of the transport mechanism          and atmospheric pathways from the source regions to Ellesmere Island,           and allow the investigations of trends in the relative composition of           the arctic aerosol trace constituents.
