  • Effect of 137Cs gamma radiation on the system bioindicator Tradescantia pallida

    The use of the bioindicator Tradescantia clone 4430 as a biomonitor is limited to a short period of time in regions of hot climate. This paper describes the use of Tradescantia pallida as a bioindicator, to verify its sensitivity to gamma radiation from a 137Cs source and to monitor places of low doses of ionising radiation in tropical climates. Specimens of the T. pallida were exposed to ...

  • Cysteine synthesis in Scorpiurum circinatum as a suitable biomarker in air pollution monitoring

    Heavy metals enter ecosystems by both natural and anthropogenic processes. An excess of metals in the environment damages plant metabolism, leading to oxidative stress in the cell. Most metal ions present in the cell are bound to low molecular mass ligands. The major types of S-containing ligands involved in metal binding are derived from cysteine. The authors show, for the first time in ...
