The lead concentration in different parts of cucumber plants, growing in "lead-free" and lead-contaminated nutrient solutions, was determined by the graphite furnace atomic absorption spectrometry technique after microwave-assisted acidic digestion of the dried plant parts. The lead accumulates first inion the roots, where its concentration can exceed 10 mg/g. In the upper parts of the plant...
Cucumber plants were grown in six different nutrient solutions with varying compounds of iron (FeCl3, Fe-citrate, or Fe-EDTA) with and without addition of lead. The concentrations of B, Ca, Cu, Fe, Mg, Mn, Ni, Pb, and Zn in the third leaves of the plants were determined by inductively coupled plasma-atomic emission spectrometry after microwave-assisted acidic digestion of the dried samples. In the...
