Atmospheric deposition of Pb onto plants has often been considered to be of greater importance than root uptake and translocation to edible portions of plants. However, Pb has an index of accumulation of 10 −1 –1.0, which is in the same range as Cu and Zn (Kabata-Pendias and Pendias, 1992). Therefore genotypic differences in accumulation ...
