Distribution of the elements Cu-Pb-Zn in soils map 168 (Algeria)

Abstract

The aim of this study was the spatial analysis of the elements copper, lead and cinc in soil of the plate 168 (Algeria), located in the southeastern region of Antioquia Colombia. The samples used are part of the "Survey and compilation of information-Map Regional Geochemistry-Ingeominas (Colombia)" and were facilitated by Ingeominas for the project "Geochemical Map of Antioquia". For the preparation of the corresponding baselines, were applied lognormal kriging geostatistical techniques. The assessment of pollution by heavy metals Cu-Pb-Zn in soil horizon plate 168, was developed taking into account the analysis of the background level, Environmental Accumulation and the Index enrichment. The results obtained indicate that content available for the elements Cu-Pb-Zn in these soils pose no real danger to be lower than its content phytotoxicity threshold given by some authors.
