Determination of pollutant elements in agricultural soil using X-Ray Fluorescence Spectrometry

Abstract

This study investigates the impact of agricultural practices on soil quality in Fundeni Commune, Galati County, with a particular focus on the potential contamination by heavy metals. Soil samples were collected from representative agricultural areas, including a vegetable garden, an alfalfa field, and two vineyards. The
concentrations of heavy metals were determined using X-ray fluorescence (XRF) spectroscopy, allowing both
qualitative and quantitative assessment. The analytical results indicated that, while the majority of measured
elements were within permissible limits, certain samples exhibited concentrations exceeding the normal
thresholds for arsenic (As), zinc (Zn), chromium (Cr), nickel (Ni), copper (Cu), and cadmium (Cd), suggesting
localized contamination potentially linked to agricultural inputs.
