“…The deposition of chromium was more in roots as compared to shoots of the plants, r = .998 and significant at p < .01 (Table 4). The bioaccumulation of Cr in roots and shoots of weeds grown in South Kaliapani area of Sukinda showed that roots have accumulated more Cr than shoots 41 . The accumulation of chromium gradually upsurges in roots and shoots of the plants with increase in the concentration of chromium (Figure 4).…”

Pot experiments were conducted for 60 days to investigate the phytoremediation potential of Cassia tora grown in different concentrations of chromium (Cr) rich overburden soil (OBS) of Sukinda Chromite Mine (10, 20, 30, 40, 50, 70, and 100%). To assess the phytoaccumulation ability of C. tora, the tolerance index (TI), bio‐concentration factor (BCF), transportation index (Ti), and total accumulation rate (TAR) were measured. The results showed that at 100% OBS the TI, BCF, Ti, and TAR of C. tora have 23.89, 0.28, 60.25, and 7.46, respectively. The Cr recovery from contaminated soil by C. tora was notable as reported to be 6.25, 11.6, 12.75, 14.2, 17.35, 22.65, and 17.7 mg/kg, respectively. The outcome indicated that C. tora is a potential phytoremediator of Cr from contaminated sites due to its high bioaccumulation activity, high tolerance, and Ti. Therefore, C. tora can be suggested for phytostabilization program to lessen toxic Cr from chromite overburden mining sites.

“…Thus, the phytoremediation process will increase the fraction of metals bioavailable for plants depending on a combination between plant physiology, soil microorganisms (see Section 3.1), soil chemistry and the interaction between plant and microbes. There are many reviews that inventory these hyperaccumulators or high biomass accumulating plants used as a function of the major trace metals or metalloids they accumulate [14,19,20].…”

Soil Contamination - Threats and Sustainable Solutions

View full text Add to dashboard Cite

Urbanization and industrialization are the main causes of increasing contaminated soils in cities all around the world. This leads to numerous abandoned lands, reduction in biodiversity, and thereby posing a serious health risk for urban inhabitants. The development of effective and ecological remediation approaches is necessary. Phytoremediation is well known as an ecological solution with good acceptation for remediation of contaminated soils. Since, urban soils are particularly characterized by their highly disturbed, heterogeneous and low fertility, the application of phytoremediation to rehabilitate contaminated soils in urban areas is until now very limited at the laboratory scale and even less at the field scale. In this context, we have to take into account all these parameters and precautions when it's application. The main objective of this chapter is to discuss how to take phytoremediation approaches from a proven technology to an accepted practice in an urban context. An overview of urban soil types is provided following phytoremediation's application for urban soils with the focus on inorganic and organic pollutants, to provide a frame of reference for the subsequent discussion on better utilization of phytoremediation. At last, we offer suggestion on how to gain greater acceptance for phytoremediation by urban inhabitants.

“…La Phytoremediationè una tecnica di biorisanamento che utilizza piante per rimuovere, degradare e immobilizzare contaminanti sia organici che inorganici dal suolo 3 . In funzione delle caratteristiche del suolo, della tipologia di pianta utilizzata per il processo e del contaminante da trattarè e possibile identificare diversi meccanismi di Phytoremediation 4 . La contaminazione del suolo a causa dei metalli pesantiè una grave minaccia per l'umanità edè una preoccupazione che si estende a livello globale 5 .È noto che i metalli pesanti come piombo (Pb), mercurio (Hg), cromo (Cr) e alcuni metalloidi come arsenico (As), selenio (Se) e antimonio (Sb) sono altamente tossici per l'uomo anche a piccole dosi e quindi, alcune di esse sono classificate tra le sostanze più pericolose 67 .…”

La problematica dei siti contaminatiè di grande attualità e assume un'importanza estremamente rilevante nell'ambito del rischio ambientale e della salute pubblica. I contaminanti del suolo, infatti, possono essere caratterizzati da alti livelli di tossicità, di persistenza nell'ambiente e da una certa mobilità che può portare alla contaminazione delle acque sotterranee e alla catena alimentare, fino a diventare fonte di pericolo per la salute umana. I siti contaminati
