| description | Soils contaminated with radionuclides pose a long-term radiation hazard to human health through food chain exposure and other pathways. The uptake, accumulation, and distribution of <sup>133</sup>Cs, individual <sup>88</sup>Sr, and combined <sup>88</sup>Sr + <sup>133</sup>Cs, with their physiological and biochemical responses in greenhouse-potted soil-based cucumber (<i>Cucumis sativus</i> L.), were studied. The results from the present study revealed that the uptake, accumulation, TF, and BCF ability of cucumber for <sup>88</sup>Sr + <sup>133</sup>Cs were greater than for <sup>133</sup>Cs and <sup>88</sup>Sr while the concentration was the same in the soil (10, 20, 40, 80, and 160 mg kg<sup>−1</sup>). The highest <sup>88</sup>Sr + <sup>133</sup>Cs accumulation was 2128.5 µg g<sup>−1</sup>dw, and the highest accumulation values of <sup>133</sup>Cs and <sup>88</sup>Sr were 1738.4 µg g<sup>−1</sup>dw and 1818.2 µg g<sup>−1</sup>dw (in 160 mg kg<sup>−1</sup>), respectively. The lowest <sup>88</sup>Sr + <sup>133</sup>Cs, <sup>133</sup>Cs, and <sup>88</sup>Sr accumulation values were 416.37 µg g<sup>−1</sup>dw, 268.90 µg g<sup>−1</sup>dw, and 354.28 µg g<sup>−1</sup>dw (10 mg kg<sup>−1</sup>), respectively. MDA content was higher under <sup>88</sup>Sr and <sup>133</sup>Cs stress than under <sup>88</sup>Sr + <sup>133</sup>Cs stress. Chlorophyll content increased at 10 and 20 mg kg<sup>−1</sup>; however, it decreased with increasing concentrations (40, 80, and 160 mg kg<sup>−1</sup>). Proline content and the activities of CAT, POD, and SOD were lower under <sup>133</sup>Cs and <sup>88</sup>Sr than <sup>88</sup>Sr + <sup>133</sup>Cs stress. The <sup>88</sup>Sr, <sup>133</sup>Cs, and <sup>88</sup>Sr + <sup>133</sup>Cs treatment concentrations sequentially induced some enzymes over 60 days of exposure, suggesting that this complex of antioxidant enzymes—CAT, POD, and SOD—works in combination to reduce the impact of toxicity of <sup>88</sup>Sr, <sup>133</sup>Cs, and <sup>88</sup>Sr + <sup>133</sup>Cs, especially in young leaves. It is concluded that cucumber reveals considerable phytoremediation capabilities due to unique growth potential in contaminated substrate and is suitable for the bioreclamation of degraded soils. The plant is especially applicable for efficient phytoextraction of <sup>88</sup>Sr + <sup>133</sup>Cs contamination. |
