One of the most important aspects regarding food safety is the heavy metal content of food and agricultural products. Due to the rapid development of different industries and other anthropogenic activities, the environmental contamination suffered an exponential increase. The assessment of the soils and crops heavy metal content is unavoidable nowadays, even mandatory for specific products. Also, it provides important information regarding the characterization of a specific area, of the soils properties variations and allows correlations between different elements and agricultural practices. Our study aims to evaluate some of the most common heavy metals (Pb, Cd, Ni, Co, Zn, Cu, Mo, As and Cr) found in one calcaric alluvial soil from Buzau county used for tomato cultivation in organic farming system. We aimed both to establish the compliance with national and European legislation and determine a correlation between these elements, in the context of using microbial inoculants for crop protections. The soil samples were taken only from the surface layers (0-20 cm depth), from plots planted with Florina 44 tomato variety, microwave digested and the elements were quantified using ICP-MS method. The obtained values showed that the soil content is within the legislation limits and allowed us to illustrate some correlations between different heavy metals.
