A Quantitative Determination of Atmospheric Deposition Sources in the #x201C;Campo de Gibraltar#x201D; Region, Using Factor Analysis and Chemical Element Balance

摘要

Factor analysis and chemical element balance were employed to identify and quantify the major atmospheric deposition sources at 12 sampling stations in the #x201C;Campo de Gibraltar#x201D; Region. The data were best represented with 5 sources: soil, marine aerosol, residual fuel oil, refuse and limestone. Predicted concentrations account for about 80 of measured total deposition.
