A Case Study of Cd, Hg and Pb Spatial Distributions by RS and GIS in Agriculture Soil

Abstract:

The objective of this agricultural geochemistry survey project was to study the enrichment distribution of Cd, Pb and Hg in the agricultural soil in Mianyang City, sichuan Province China. More and more geochemists in field of agricultural geology become to concern heavy metal (Cd, Pb and Hg) pollution problems in soil. Basing on geochemical investigation method, and employing remote sensing ( RS ) and geographic information system (GIS) techniques and methods, it indicates that the distributions of soil Cd, Pb and Hg are controlled by the terrain and landform features, and human constructions in working site. The study shows as well that distributions of Cd, Pb and Hg contents are influenced by highway and river, and there is enriching tendency of Cd in the project site with the risk of contamination.
