ABSTRACT

Trace elements (TE) occur naturally in soils, being the principal source for plants. The
TE content of the plant depends on soil formation and plant type. According to the plant
nutritional necessities, the concentration of trace elements is useful in plant nutrition,
but the plant growth and crop quality can be affected if trace element concentrations are
lower or higher than normal needs. The presence of potentially toxic TE (Cd, Cr, Pb, As)
caused by the long exposure of soil or plant to different agrochemical treatments is a great
concern for environmental and food chain contamination. In some conditions the
micronutrients can have toxic effects in the presence of elevated concentration which
affect the plant metabolism.
A number of 32 soil and leaf samples were collected from a vineyard area from Huşi
area (Eastern part of Romania), during July-August 2010. Analyses were performed
using ICP-MS after microwave digestion of the samples. Abundance of TE in soil is
described by following order Cd< As Cd The leaves/soil transfer coefficient is generally low (< 1) showing that bioaccumulation
of potentially toxic TE is not related to the soil-grapevine system. Contamination of
leaves is assumed to be caused by atmospheric deposition and repeated use of foliar
sprays in viticulture.

Keywords: trace elements, vineyard, transfer coefficient, potentially toxic elements,
ICP-MS.
