Microanalysis of Airborne Lead Particulates in an Urban Industrial Environment
Automated SEM-EDX of particulates is a technically viable and economically feasible analytical technique in environmental modelling. A case study involving the microanalysis of lead particulates on aerosol filters from the Weston community of northwest Winnipeg is detailed. The sampling requirements and analytical restrictions inherent in the technique provide a complementary rather than competitive method to conventional chemical analysis techniques. Additional software enhancements to assist in database management are described for use with existing commercial particle analysis hardware/software packages.
