“…Surface water, considered an important drinking water source, is vulnerable to heavy metal pollution when wastewater is discharged into rivers, and such wastewater pollution threatens a large quantity of the population by worsening living environments (Chai et al ; Fei et al ). Heavy metal remediation methods, especially biological remediation technologies, greatly contribute to the global ecosystem (Ye et al , , ). Heavy metals are hazardous to humans and other animals via damage to the nervous system and internal organs as they accumulate (Lohani et al ); therefore, their assessment and quantification have attracted significant attention (Pertsemli and Voutsa ; Gao et al ; Liu et al ).…”

Pollution by heavy metals in river water is becoming a major subject of global drinking water concern, and the Xiangjiang River is one of the most heavily polluted rivers in China. Water samples were collected from 17 sites spanning the entire Xiangjiang watershed from 2005 to 2016 to investigate spatial–temporal distributions and potential human health risks related to 8 metal pollutants (As, Cd, Hg, Cr, Cu, Pb, Zn, and Se). The results of spatial–temporal distribution analyses proved that most metals were below the guideline limits the majority of the time. However, the hazard index and carcinogenic risk analyses indicated that As and Cr were associated with a potential risk of cancer, although noncarcinogenic heavy metals in general and carcinogenic risk declined year by year. A nonparametric seasonal Mann‐Kendall's test revealed that there were notable decreasing trends in As, Cd, Zn, Cu, Cr, and Pb for most sites, whereas Se and Hg significantly increased in some areas over the targeted 12 yr. The results of principal component analysis agreed with those of dual hierarchical cluster analysis in the identification of pollution sources, the results of which are as follows: 1) As, Cd, Pb, Hg, and Zn were mainly derived from anthropogenic activities and the smelting industry; 2) Cr and Cu mainly originated from agricultural or industrial activities; and 3) Se was predominantly from natural erosion. The present study will be conducive to optimizing the distribution of water monitoring stations and drafting remediation strategies pertaining to the protection of public health in metal‐polluted areas.

“…BFO nanoparticles have been synthesized by various methods and are used in the degradation and mineralization of dye pollutants. The effects of different pollutants on water and soil contamination were investigated using various methods by most researchers in modern technology to efficiently develop remediation processes (Ye et al, 2017a(Ye et al, , 2017b. Also, the BFO and other related materials have been shown to be capable of utilizing visible light for photodegradation of molecules to harmless products.…”

The studies of advanced materials in environmental remediation and degradation of pollutants is rapidly advancing because of their wide varieties of applications. BiFeO 3 (BFO), a perovskite nanomaterial with a rhombohedral R3c space group, is currently receiving tremendous attention in photodegradation of dyes. The photocatalytic activity of BFO nanoparticle is a promising field of research in photocatalysis. BFO nanomaterial is a photocatalyst enhanced by doping because of its reduce bandgap energy (2.0-2.77 eV), multiferroic property, strong photoabsorption and crystal structure. The material has proven to be very useful for the degradation of dyes under visible light irradiation among other photocatalysts. Its exceptional nontoxicity, suitability, low cost and long term excellent stability makes it an efficient photocatalyst for the degradation of effluents from textile and pharmaceutical industries which ended-up in the environment and now a major concern of the modern world. This mini-review attempts to provide some detailed synthetic routes of BFO and BFO related nanomaterials and the notable achievements so far on the effect of doping the material. It also discusses the effect of crystallite size of the material and other photophysical properties and how they influence the photocatalytic process of model organic dye pollutants, to date.

Heavy metals are among the most important environmental pollutants. However, little attention has been devoted to immobilizing or fixing metal ions in soil for remediation of soil. Here, a novel and inexpensive, polymer nanocomposite (polyacrylamide-polystyrene/bentonite) is introduced for successful immobilization of cadmium (Cd) and lead (Pb) cations in the soil. The synthesized nanocomposite structure was characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy/Energy-Dispersive X-Ray Spectroscopy (FE-SEM/EDX), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET), and Fourier-Transform Infrared Spectroscopy (FT-IR). Various effective parameters such as pH, bentonite: polyacrylamide weight ratio, heavy metal concen-tration, and amount of adsorbent were investigated for fixing Pb and Cd cations in farm soil. Also, adsorption isotherms and kinetics of adsorption were investigated. Finally, under optimum conditions, the extent of adsorption of Pb and Cd cations by polyacrylamide-polystyrene/bentonite nanocomposite, polyacrylamide, and bentonite was compared. The results revealed the superior adsorption activity of the nanocomposite for immobilizing heavy metal cations as compared to bentonite or polymer. Further, the nanocomposite indicated a reasonable reusability for fixing Cd and Pb cations. Overall, the prepared nanocomposite can be applied as a suitable and industrial adsorbent for immobilizing Pb and Cd cations in soil.
