Within this paper, a study on physical and chemical features of white Jerusalem artichoke tuber’s (Helianthus tuberosus) cultivated in Southern Romania, Fetesti, Ialomita, was achieved. The Romanian Plain, where Fetesti locality is situated is characterized by unlimited fields, considered as first- class lands, namely with deep well drained and aerated soil, easy to work, presenting a good permeability and water stocking, with relative high natural fertility for most of plants of culture adapted to climate conditions and which are not difficult to be exploited as arable field. For this study, the tuber vegetal product, in fresh state, was used, being studied samples taken from the vegetal crop established near the road traffic, starting from the half part of cultivated area and from the farthest side, in order to identify the possible pollutant substances acting on minerals, oligoelements, but especially heavy metals contained by it; therefore, not only quality studies, but also complementary studies have been made in order to determine also the safety aspects of this potential source of raw active matter of natural vegetal origin for food industry, functional food, food supplements and pharmaceutical industry.
