Assessing Heavy Metals in Sediment of Beijing-Hangzhou Grand Canal by Statistical and Geochemical Analysis

Abstract

Statistical analysis and geochemical approaches were exploited for the heavy metals (HMS) assessment in sediments from Beijing-Hangzhou Grand Canal. Single source (crustal) was identified using principal component analysis (PCA). Furthermore, enrichment factor (EF) denoted contaminated sites by HMS in the study area while EF value reveal minor enrichment or no anthropogenic enrichment from most sites. The anthropogenic activities that suggested to be primarily from agriculture and automobile repair discharge.
