“…Sensitive plants exhibit symptoms of toxicity already under exposure to a Cr(VI) dose of 1–2 mg kg −1 soil (Shahid et al 2017). The changes observed in plants, such as reduced biomass yield, are indicative of the toxic effects of Cr compounds (Patra et al 2018). Plants control heavy-metal concentrations by inhibiting their root uptake and transfer to tissues or by immobilizing contaminants through the formation of bonds with biologically active molecules (Hedayatkhaha et al 2018).…”

The effect of soil amendments, i.e., compost, zeolite, and calcium oxide, on the chemical properties of soil contaminated with Cr(III) and Cr(VI) and the uptake of selected heavy metals by spring barley ( Hordeum vulgare L.) and maize ( Zea mays L.) was determined in a pot experiment. The content of all investigated heavy metals in the tested plants varied significantly in response to the tested soil amendments and increasing concentrations of Cr(III) and Cr(VI). Compost, zeolite, and calcium oxide contributed to an increase in the average yield of the aerial parts of maize plants only in treatments contaminated with Cr(III). The concentrations of Cr, Zn, and Ni in the aerial parts of spring barley and maize were higher in treatments contaminated with Cr(III) than in treatments contaminated with Cr(VI). Calcium oxide induced a significant increase in soil pH relative to the control treatment. In treatments without soil amendments, the average Cr content of soil was higher in pots contaminated with Cr(VI). The concentrations of Zn and Cu in non-amended treatments were negatively correlated with increasing doses of Cr(III) and Cr(VI). Calcium oxide decreased the average content of Cr, Cu, and Ni in all experimental variants. Compost increased the average content of Zn in treatments contaminated with Cr(III) and Cr(IV) relative to non-amended soil.

“…It noted that higher concentration of chromium in mine adjoining areas poses threat to biotic communities due to the fact that the metal is toxic to biological system 5,6 . Metabolic alterations by chromium exposure have also been described in plants either by a direct effect on enzyme or other physiological changes or by alterations in biochemical parameters 7 . Under chromium stress, total chlorophyll and protein contents were reduced in sesban and para grass plants as Cr causes iron insufficiency in stressed plants as a result reduction in chlorophyll biosynthesis and denaturation of protein 8,9 .…”

“…With a view to tackle the severe problem of contamination of toxic Cr +6 , attempts have been taken for attenuation of Cr +6 through the use of phytoremediation technology 6,7 . In this technology plants are used to alleviate the toxic metals from polluted sites through their accumulation in harvestable aerial portions (i.e., phytoextraction) or phytostabilization of toxic metals in soil in contaminated sites.…”

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.

“…In terms of frequency, chromium is the seventh most abundant chemical element on the planet. Chromium is mostly found in the environment in two valence states, trivalent chromium (Cr III) and hexavalent chromium (Cr VI); the latter state is hazardous to both human and environment (6,7). Generally, the most important sources of chromium are leather, plating, tannery, and textile industries (8).…”

Background: Considering the carcinogenic effects of heavy metals, such as chromium, it is essential to remove these elements from water and wastewater. Direct osmosis is a new membrane technology, which can be a proper alternative to conventional chromium removal processes. Methods: The wastewater samples were collected from an electroplating unit, located in Alborz industrial city, Qazvin, Iran. Magnesium chloride was used as the draw solution, and a semipermeable membrane (Aquaporin) was used in this study. The experiments were designed, using response surface methodology (RSM) and central composite design (CCD) with draw solution concentration (0.5- 1.5 M), feed solution concentration (4-12 mg/L), and experiment time (30-90 minutes) as variable factors. The chromium concentration and water flux were also measured, based on atomic absorption spectrophotometry and water flux equation, respectively. Results: Direct osmosis was highly efficient in chromium removal and water recycling. Water flux and chromium removal efficiency were 15.6 LMH and 85.58%, respectively, under optimal conditions (draw solution = 1.27 mol/L, feed solution = 4 mg/L, and experiment time = 90 min). In terms of validity, the results predicted by the quadratic polynomial model were in good agreement with the responses reported in the laboratory. Conclusion: In direct osmosis, the use of magnesium chloride as the draw solution resulted in the acceptable chromium removal from electroplating wastewater. Using this method, chromium concentration in wastewater reduced to a level lower than the discharge standards, established by Iran’s Department of Environment.
