Heavy metal content in soil and in tobacco leaf in Croatia

In Croatia tobacco is produced on soils of different physical and chemical characteristics, which has a direct reflection on tobacco quality. For this reason, systematic field and laboratory investigations of soil and plant material were conducted in the tobacco growing region of the Drava River Valley in the period 2006-2008 with the aim to get a better insight into the soil status and tobacco quality and to eliminate the detected restraints. As luvisol on loess is the prevailing soil type on which tobacco is grown in the Drava Valley, this paper presents the investigation results relating to the contents of some heavy metals (Cd, Cr, Cu, Mn, Mo, Ni, Pb, and Zn) in this soil type and to their accumulation in tobacco leaf. Soil and plant samples were taken from 22 locations, i.e., 22 family farms. Concentrations of particular elements were determined by inductively coupled plasma optical emission spectrometry. Comparison of concentrations of the investigated metal with allowable threshold values showed that soils used for tobacco productions are not contaminated by heavy metals, since their concentrations are below allowable threshold values and that the heavy metal content in dried tobacco leaf is in accordance with literature values.Comparison between the content of heavy metal contents in soil and tobacco leaf, suggests that there is no significant statistical dependence, which shows that accumulation of studied metals in leaf is not influenced by their content in the soil, but is rather a consequence of the interaction of pedophysical and pedochemical parameters, as well as of the applied technology.
