AbstractChromium (Cr) is a common toxic heavy metal that is widely used in all kinds of industries, causing a series of environmental problems. Nanoscale zero- valent iron (nZVI) is considered to be an ideal remediation material for contaminated soil, especially for heavy metal pollutants. As a material of low toxicity and good activity, nZVI has been widely applied in the in situ remediation of soil hexavalent chromium (Cr(vi)) with mobility and toxicity in recent years. In this paper, some current technologies for the preparation of nZVI are summarized and the remediation mechanism of Cr(vi)-contaminated soil is proposed. Five classified modified nZVI materials are introduced and their remediation processes in Cr(vi)-contaminated soil are summarized. Key factors affecting the remediation of Cr(vi)-contaminated soil by nZVI are studied. Interaction mechanisms between nZVI-based materials and Cr(vi) are explored. This study provides a comprehensive review of the nZVI materials for the remediation of Cr(vi)-contaminated soil, which is conducive to reducing soil pollution.

Abstract Heavy metals are among the most dangerous contaminants in the environment. Application of organic compounds and plant species with the ability to accumulate and stabilize heavy metal in their organs is the best option for remediation of these elements in the soil. Therefore, this study aimed to investigate the effects of manure and biochar on the accumulation of heavy metals by Salicornia species. Two species of Salicornia ,including S. persica and S. perspolitana, were cultivated outdoor in experimental pots. The effects of experimental treatments ,including hexavalent chromium concentrations, manure ,and biochar on the two studied species, were investigated. The results indicated a significant effect (P < 0.05) of biochar on the accumulation of heavy metals by two species ,S. persicaand S. perspolitana, so that chromium concentrations in the roots and shoots were 258 and 5.41 mg/kg, respectively. Also, chromium accumulations under manure treatments in the roots and shoots were 334.34 and 9.79 mg/kg, respectively. Plant dry weight and height for both species in manure treatment were higher than control and biochar treatments. S. persica showed higher growth than S. perspolitana species. The content of photosynthetic pigments in both S.persica and S. perspolitana species under biochar treatment was higher than control and manure treatments. In general, one can conclude that the accumulation of chromium in S. perspolitana was higher than in S. persica ,and the application of biochar and manure amendments could stabilize chromium in soil and reduce chromium accumulation in both S. persica and S. perspolitana species.
