A STUDY REGARDING CORRELATION BETWEEN CONTENTS IN SOIL AND CONTENTS IN PARSLEY ROOTS OF CADMIUM, LEAD, ZINC AND COPPER IN SAMPLES COLLECTED FROM PRIVATE GARDENS IN COPSA MICA

Abstract

Food security is a high-priority issue for sustainable global development both quantitatively and qualitatively. The increasing contamination of heavy metals in vegetables is attributed to multiple pathways, such as industrial emissions, sewage sludge discharge, agrochemicals and fertilizers abuse, and it has become a serious issue worldwide, especially in developing countries. CopşaMicăhad the reputation of being the most polluted city in Europe until the Chernobyl nuclear accident. This was due to emissions from two factories Carbosin, which produced carbon black and Sometra, the other source of pollution, less visible, but much more serious from the point of view of the impact on the human health.For this study, were collected soil and parsley (Petroselinum crispum) samples from 36 households located in CopşaMică area. The obtained data were used to estimate the accumulation of cadmium, lead, zinc and copper in parsley roots. by correlation factor between contents in soil and contents in parsley roots. For cadmium and lead, the value of linear correlation coefficient is r = 0.571 for cadmium and r = 0.381 for lead and it is indicating a good correlation between the cadmium and lead content in parsley roots and the cadmium and lead content in soil. For zinc and copper, the value of the linear correlation coefficient is r = 0.139 for zinc and r = 0.035 for copper is not significantly different from zero, indicating that the estimation of zinc and copper accumulation in parsley roots cannot be described by simple power-type regressions.
