Meenambal Computación Geo Heavy metals accumulation Spatial analysis Universal kriging Coimbatore is a fast growing city, Manchester of Tamil Nadu, India. In Coimbatore Industry effluents and wastes being discharged randomly on soil, river, lake and road side without any treatment. They pollute productive soil, natural water system as well as ground water. Assessment of heavy metal content in soil and wetland from various localities of Coimbatore, Tamil Nadu was undertaken. Heavy metal pollution generally a non-stationary variable, the technique of universal kriging is applied in preference to ordinary kriging as the interpolation method. Topsoil samples (0-20 cm) were taken at various locations with reference to latitude and longitude. The concentration of heavy metal As, Hg, and Cd were analyzed in the Atomic Absorption spectrometer. Universal Kriging model was developed with suitable empirical semivariogram model. The model having the least error was selected by comparing the observed water-table values with the values predicted by empirical semivariogram models. It was determined that the presence of As is high at SIDCO. Presence of Hg is high in Sanganur road. Presence of Cd is high at Sanganur and townhall were because of electroplating industries. The aim of this analysis is to investigate the level, causes of heavy metal contamination in soil and prediction of heavy metal at various locations in the vicinity of industries and around Coimbatore city. 2013 artículo científico 2007-1558 https://www.redalyc.org/articulo.oa?id=265229633004 en http://www.redalyc.org/revista.oa?id=2652 International Journal of Combinatorial Optimization Problems and Informatics application/pdf International Journal of Combinatorial Optimization Problems and Informatics International Journal of Combinatorial Optimization Problems and Informatics (México) Num.2 Vol.4 |
