“…The physical removal strategies include excavation, hydraulic ushing, and electrokinetics. A drawback of the physical removal techniques is the disruption of soil structure (Isidro et al, 2022;Kumawat et al, 2022;Zheng et al, 2022). By contrast, Pb-phytoremediation is an in-situ applicable technique that is e cient, eco-friendly, and cheap (Khan et al, 2019;Yadav et al, 2022;Singh and Pant, 2023).…”

Phytoextraction of Pb is a challenging task due to its extremely low mobility within soil and plant systems. In this study, we tested the influence of some novel chelating agents for Pb-phytoextraction using sunflowers. The Pb was applied at control (0.0278 mM) and 4.826 mM Pb as Pb(NO3)2 through soil-spiking. After 10 days of Pb addition, four different organic ligands (aspartic, ascorbic, tartaric, and pantothenic acids) were added to the soil at 1 mM concentration respectively. In the absence of any chelate, sunflower plants grown at 4.826 mM Pb level accumulated Pb concentrations up to 104 µg g-1 DW in roots whereas, 64 µg g-1 DW in shoot. By contrast, tartaric acid promoted significant Pb accumulation in root (191 µg g-1 DW; +45.5%) and shoot (131.6 µg g-1 DW; +51.3%). Pantothenic acid also resulted in significant Pb-uptake in sunflower shoots (123 µg g-1 DW; +47.9%) and in roots (177.3 µg g-1 DW; +41.3%). The least effective amongst the chelates tested was ascorbic acid but it still contributed to +39.0 and 45.2% more Pb accumulation in sunflower root and shoots. In addition, plant growth, biochemical, and ionomic parameters were positively regulated by organic chelates. Especially, an increase in the leaf Ca, P, and S was evident in Pb-stressed plants in response to chelates. These results highlight that the use of biocompatible organic chelates positively alters plant physio-biochemical traits contributing to higher Pb-sequestration in sunflower plant parts.

Environmental remediation is a dynamic field aimed at removing pollutants from natural ecosystems. This chapter explores key pollutant degradation mechanisms, including biological, chemical, and physical methods, and their integration into water and soil remediation techniques. Fused S-heterocycles—compounds with unique chemical properties—play a central role in enhancing these processes. In biological remediation, they act as catalysts or mediators, boosting microbial activity and enzymatic processes. In chemical degradation, including advanced oxidation processes like photocatalysis and ozonation, fused S-heterocycles improve light absorption and electron transfer. Physical methods, such as adsorption and filtration, are optimized by incorporating these compounds into adsorbents. Water remediation techniques, including phytoremediation, bioreactors, and membrane filtration, are enhanced by fused S-heterocycles, which improve microbial activity, and membrane efficiency. These heterocycles offer eco-friendly, innovative solutions for sustainable, long-term environmental restoration.
