Tőzsér D, Horváth R, Simon E, Magura T. Heavy metal uptake by plant parts of Populus species: a meta-analysis. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:69416-69430. [PMID: 37131011 DOI: 10.1007/s11356-023-27244-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 04/22/2023] [Indexed: 05/04/2023]
Abstract
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.

Abstract
A long term experiment was conducted to verify the phytoremediation effect of large biomass plants and to seek the balance between remediation effect and economy. Eucalyptus globulus were planted with rotation periods of respectively 3, 6 and 9 years to examine the effect on soil remediation. Biomass and concentrations of Cd, Pb and Cu in E. globulus were measured after each harvest. The economic value of the plant was estimated. Results showed E3 (9th year uprooted) had the best soil remediation effect and economic benefit. Therefore, soil remediation and economy were best balanced when E. globulus were not cut.

Sluchyk V, Sluchyk I, Shyichuk A. Assessment of both environmental cytotoxicity and trace metal pollution using Populus simonii Carr. as a bioindicator. ENVIRONMENTAL MONITORING AND ASSESSMENT 2014; 186:6645-6650.

Abstract
The level of environmental pollution in the city of Ivano-Frankivsk (Western Ukraine) has been assessed by means of roadside poplar trees as bioindicators. Dividable apical meristem cells of rudimentary leaves were quantitatively analysed for mitotic activity and distribution. Anaphases were further examined for chromosomal aberrations. Male catkins were also examined for sterile pollens. Accumulation of trace elements in vegetative buds was also evaluated in order to reveal source(s) of environmental pollution. Poplar trees growing in the urban environment proved to have increased chromosomal aberrations (up to 4-fold) and increased pollen sterility (up to 4-fold) as well as decreased mitotic activity (by factor 1.5) as compared to control sampling site. The biomarker data correlate moderately with increased (up to 4-fold) concentrations of Ni, Zn, Pb, Cd and Cu in vegetative tissues suggesting that probable cause of the environmental cytotoxicity may be vehicle emissions. The maximum increase in chromosomal aberrations (7-fold) and the minimum mitotic activity (half of the control one) were recorded in poplar trees growing in industrial suburb in vicinity of large cement production plant. Taking in mind insignificant bioaccumulation of trace elements in the industrial suburb, the high environmental toxicity has been ascribed to contamination in cement and asbestos particulates.

Abstract
The present study investigates the ability of two genus of duckweed (Lemna minor and Spirodela polyrhiza) to phytoremediate cadmium from aqueous solution. Duckweed was exposed to six different cadmium concentrations, such as, 0.5,1.0,1.5, 2.0, 2.5, and 3.0 mg/L and the experiment was continued for 22 days. Water samples were collected periodically for estimation of residual cadmium content in aqueous solution. At the end of treatment period plant samples were collected and accumulated cadmium content was measured. Cadmium toxicity was observed through relative growth factor and changes in chlorophyll content Experimental results showed that Lemna minor and Spirodela polyrhiza were capable of removing 42-78% and 52-75% cadmium from media depending upon initial cadmium concentrations. Cadmium was removed following pseudo second order kinetic model Maximum cadmium accumulation in Lemna minor was 4734.56 mg/kg at 2 mg/L initial cadmium concentration and 7711.00 mg/kg in Spirodela polyrhiza at 3 mg/L initial cadmium concentration at the end of treatment period. Conversely in both cases maximum bioconcentration factor obtained at lowest initial cadmium concentrations, i.e., 0.5 mg/L, were 3295.61 and 4752.00 for Lemna minor and Spirodela polyrhiza respectively. The present study revealed that both Lemna minor and Spirodela polyrhiza was potential cadmium accumulator.
