Caesium-133 Accumulation by Freshwater Macrophytes: Partitioning of Translocated Ions and Enzyme Activity in Plants and Microorganisms

The potential of aquatic plants to accumulate Cs may be notable importance in the environmental monitoring radioactive wastes. This study aimed evaluate accumulation Cs-133 by freshwater macrophytes Bacopa amplexicaulis, Elodea densa, Ceratophyllum submersum, and Limnobium laevigantum after a 10-day incubation period with CsCl (1–1000 μM). partitioning other elements, including 21 metals, such as P, B, As, was analyzed using inductively coupled plasma mass spectrometry combined principal component analysis (PCA). enzymatic activity plant crude extracts microorganisms characterized. transfer factor (TF) reached highest values 0.13 0.10 for C. submersum L. laevigantum, respectively, at 1000 μM Cs. TFs sets were below 0.1. In presence Cs-133, there significant increase dehydrogenase (p < 0.05) decrease Folin–Ciocalteu assay. A three-fold culturable found PCA revealed species-specific elemental distribution biomass phase. negative correlation between Na, Ca (2.0–2.5, PC1) Mg, K, P (−2, found. Certain enzyme groups can serve bioindicators pollution ecosystems.
