Heavy metal determination in agricultural soil collected from Brăila County

Abstract

This is a study conducted on agricultural soil collected from village of Dudescu, Zăvoaia Commune, Însurăței City, Brăila County. In this case soybeans, sunflowers, corn and wheat have been cultivated prior the soil sampling. The soil was analyzed using an ED-XRF and the results indicated, in general, elements concentrations within normal values, indicating a good soil quality. The exceptions in this study, which have exceeded the normal legal values, were: chromium (Cr), nickel (Ni) and arsenic (As). To assess the level of soil pollution, different types of indexes were calculated such as the migration index (MI) and the ecological risk potential (RI).
