Consecutive and single Tenax extractions were applied to characterize the effectiveness of activated charcoal (AC) amendments to reduce the phytoavailability of dieldrin in a natively contaminated horticultural soil. Dieldrin desorption from untreated and 800 mg(AC) kg(-1) soil was well described by a model with three dieldrin fractions of different kinetics: a rapidly (F(rap)), slowly (F(slow)), and very slowly (F(v.slow)) desorbing fraction. The AC amendment resulted in a transfer of dieldrin from the F(slow) to the F(v.slow) fraction. The F(v.slow) increased by nearly 10% compared to the control soil. Dieldrin extractability by Tenax from AC amended soils was not influenced by the cultivation of cucumber plants indicating the stability of this remediation technique. Dieldrin extractability by Tenax at the beginning of plant growth correlated only weakly with the dieldrin content of the cucumbers at harvest. Therefore, the potential of Tenax extractions to predict the uptake of dieldrin by cucumbers appears to be limited.
