2020, Journal of Hazardous MaterialsCitation Excerpt :The bioavailability of five fractions follows the order of EX > CB > OX > OM > RS (Su et al., 2016). Some chemical accelerators can transform the non-bioavailable Hg into bioavailable fractions (Moreno et al., 2005; Wang and Greger, 2006; Wang et al., 2011; Cassina et al., 2012; Pedron et al., 2013; Smolinska, 2015; Smolinska and Rowe, 2015; Rodríguez et al., 2016; Smolinska and Szczodrowska, 2017; Wang et al., 2017; Liu et al., 2018b; Li et al., 2019a, 2019c). Wang and Greger reported that addition of potassium iodide (KI) could increase the bioavailability of Hg in Hg-contaminated soils which could promote the phytoextraction of Hg-contaminated soils, despite the fact that too high concentrations of iodide might be toxic to willow (Wang and Greger, 2006; Table 1).
Improved arsenic phytoextraction by combined use of mobilizing chemicals and autochthonous soil bacteria
2019, Science of the Total EnvironmentCitation Excerpt :In this context, thiosulfate can be very promising in the case of mercury (Hg) contamination, being a mobilization agent without negative effects on the environment. In fact, it is a common fertilizer, used to promote plant growth, and recent studies have shown that it forms stable soluble complexes with Hg in soil (Pedron et al., 2013; Wang et al., 2014), thus promoting the uptake of this metal by growing plants. Moreover, thiosulfate competes with arsenate ions for sorption on oxide surfaces, thus increasing the bioavailability of arsenic and providing the interesting possibility of co-extracting this metal through plants uptake (Petruzzelli et al., 2014).
