Article

There is indirect evidence of heavy metal build-up in some agricultural soils due to long-term application of inorganic phosphate fertilizers (Ewa et al. 1999). Trace elements are normally found in phosphate fertilizers (Lee et al. 1997; Todorova and Dombalov, 1995), and fertilization for long periods increases their concentration in soils (He and Singh, 1993b; Taylor, 1997). These elements are absorbed by plants, and some are contaminants, which might become a risk for the environment and health. Among these elements is cadmium, which is considered to be one of the most dangerous heavy metals (Lee et al. 1997 because of its high mobility (Barcelo and Pochenrieder, 1992) and its ability to accumulate in plants in large quantities without any visible signs (Lehoczky et al. 1996).

The uptake of Cd by plants increases with an increased application rate of phosphate fertilizers (Pezzarossa et al. 1993). Thus, increased Cd in the soil leads to increased Cd in crop plants (Zarcinas et al 1999...
