THE ANALYSIS OF THE HEAVY METALS IN THE CORN AGRICULTURAL ECOSYSTEM IN THE AXENTE SEVER-COPSA MICA AREA (SIBIU COUNTY)

The invertebrates constitute important indicators in the appreciation of the soil. A first step in this respect is constituted by the analysis of the heavy metals in the corn fields in the Axente Sever and Copsa Micaƒ Area. Methods of researching: collecting the samples in the soil by using the agricultural drill; the determination of the heavy metals by spectroscopy of atomic absorption, using the spectrometer of atomic absorption ContrAA 700. As a result of the researches the average concentration of lead and cadmium in the soil of the agricultural ecosystems from the studied area is still high.
