Effect of illite and birnessite on thallium retention and bioavailability in contaminated soils.

The influence of illite and birnessite (δ-MnO(2)) amendments on the retention and bioavailability of Tl in contaminated soils was investigated. The efficiency of both phases was evaluated using Tl uptake by white mustard (Sinapis alba L.), sequential extraction and sorption experiments.

Thallium uptake by white mustard (Sinapis alba L.) grown on moderately contaminated soils--agro-environmental implications.

The work focused on Tl uptake by white mustard (Sinapis alba L.) grown on moderately contaminated soils with different characteristics. The data presented here clearly demonstrate the ability of white mustard to (hyper)accumulate Tl.
