Abstract: |
The robust statistical analysis and factor analysis were used to study the contaminative sources in typical polluted urban soils by heavy metal contents (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn). It could be concluded that the distribution of heavy metal was mainly affected by transportation factors, industry factors and natural factors originated from human inputs. The locations of pollutant source obtained by our robust statistical method were identical with the true pollutant points.
