Cím:	Do Soil Amendments have a Significant Influence on Element Accumulation in Plant Organs? A Meta-analysis / Daniela Isabel Gutiérrez Pérez, Szabolcs Mizser, Roland Horváth, Dávid Tőzsér

Megjegyzések:	Soil amendments generally impact overall soil health and phytoremediation strategies; however, their effects on element accumulation vary and are inconsistent. This meta-analysis examined data from nine independent studies published between 1975 and 2024 to assess how amendments such as manure, sewage sludge, compost, biochar, peat moss, and lime influence metal accumulation in plants compared to plants grown in unamended soils. Hedges' g values were calculated using a random effects model to compare metal accumulation related to amendment use. Additionally, linear regression analysis evaluated how pH and exposure time affect element accumulation. Results showed that amendments significantly reduced overall plant accumulation of As (p?<?0.001), Cd (p?<?0.001), Cr (p?=?0.005), Cu (p?=?0.004), Pb (p?<?0.001), and Zn (p?=?0.013). For the plant-organ comparison, only root arsenic concentrations were significantly lowered by amendments. Exposure time was positively correlated with the accumulation of Cd, Cu, Mn, Ni, Pb, and Zn in whole plants during amendment application. Regarding pH, higher levels increased root arsenic concentrations but decreased levels of Cd, Cr, and Ni in leaves and roots, as well as Cu in leaves, and Mn and Pb in roots. In conclusion, although amendments can reduce overall plant metal accumulation, this effect is influenced by multiple factors; exposure time, soil pH, and other variables such as amendment type and decomposition stage, all affect metal mobility in various ways and account for the high variability observed across studies.

Cím:	Heavy metal uptake by plant parts of Populus species: a meta-analysis / Dávid Tőzsér, Roland Horváth, Edina Simon, Tibor Magura
Dátum:	2023

Megjegyzések:	Populus species are well documented for being potentially suitable for phytoremediation purposes regarding their accumulation characteristics. However, published results are contradictory. Based on the data gathered during an extensive literature search, we aimed to assess and revise the metal accumulation potential in the root, stem, and leaf of Populus species growing in contaminated soils, with meta-analysis. We evaluated the influences of pollution level, soil pH, and exposure time on the metal uptake patterns. We found accumulations of Cd, Cr, Cu, Pb, and Zn to be significant in each plant part, while that was only moderate for Ni, and limited for Mn. By calculating the soil pollution index (PI), we observed significantly intensive, PI-independent accumulation for Cd, Cr, Cu, Ni, Pb, and Zn. A decrease in soil pH significantly increased the uptake of Mn and significantly decreased the accumulation of Pb in the stem. Metal uptake was significantly influenced by exposure time as well; Cd concentration was significantly decreased in the stem, while concentrations of Cr in the stem and leaf, and Mn in the stem were significantly increased with time. These aforementioned findings support a well-founded metal-and-growth condition-specific application of poplars in phytoremediation processes, also triggering further in-depth assessments to enhance the efficiency of relevant poplar-based technologies.
