“…Similarly, TBBPA also induces inflammatory responses in other organs such as lung [ 12 ] and skeletal muscle of mice. [ 35 ] These findings indicate critical roles of inflammatory response in TBBPA‐associated toxicity. Finally, the disruption of liver microenvironmental and increased cell‐cell communications, especially the interaction of T cells with other cells of the liver is critical for TBBPA‐induced cell injury.…”

In recent years, there has been growing concern over the rising incidence of liver diseases, with increasing exposure to environmental toxins as a significant contributing factor. However, the mechanisms of liver injury induced by environmental pollutants are largely unclear. Here, using tetrabromobisphenol A (TBBPA), a widely used brominated flame retardant, as an example, environmental toxin‐induced liver toxicity in mice is characterized via single‐cell sequencing technology. Heterogeneous gene expression profiles after exposure to TBBPA in major cell types of the liver are demonstrated. In hepatocytes, pathway analysis of differentially expressed genes reveals the enhanced interferon response and diminished metabolic processes. The disrupted endothelial functions in TBBPA‐treated cells are then shown. Moreover, the activation of M2‐polarization in Kupffer cells, as well as activated effector T and B cells are unveiled in TBBPA‐treated cells. Finally, ligand‐receptor pair analysis shows that TBBPA disrupts cell‐cell communication and induces an inflammatory microenvironment. Overall, the results reveal that TBBPA‐induced dysfunction of hepatocytes and endothelial cells may then activate and recruit other immune cells such as Kuffer cells, and T/NK cells into the liver, further increasing inflammatory response and liver injury. Thus, the results provide novel insight into undesiring environmental pollutant‐induced liver injury.

“…The specific surface areas of FP and FP-nZVI were 1.517 m 2 /g and 3.963 m 2 /g, respectively. The enlarged specific surface area of FP-nZVI can provide more active sites and contact area for the degradation of pollutants, thus improving the removal efficiency [49]. The average pore size of FP-nZVI was 5.770 nm, and the pore volume was 0.010 cc/g, indicating that the material was structurally porous and could also provide many reduction and adsorption sites for pollutants.…”

Cr(VI) pollution in water bodies is very harmful to human health and the environment. Therefore, it is necessary to remove Cr(VI) from water. In this study, the composite (FP-nZVI) was prepared by loading nano-zero-valent iron (nZVI) onto cellulose filter paper (FP) using a liquid-phase reduction method to improve the dispersibility and oxidation resistance of nZVI. In batch experiments, the effects of iron loading of FP-nZVI, initial concentration of Cr(VI), temperature, and pH on Cr(VI) removal were particularly investigated. The maximum removal rate of 98.6% was achieved at 25 °C, pH = 5, initial concentration of Cr(VI) of 20 mg/L, and FeCl3·6H2O solution concentration of 0.8 mol/L. The removal of Cr(VI) by FP-nZVI conformed to a pseudo-second-order kinetic model and Langmuir isotherm model. The mechanism of Cr(VI) removal was a multi-step removal mechanism, involving adsorption, reduction, and coprecipitation. Column experiments investigated the effect of flow rate (1 mL/min, 3 mL/min, and 5 mL/min) on Cr(VI) removal. We found that increasing flow rate slightly decreased the removal rate of Cr(VI). The transport of Cr(VI) in composite porous media was simulated using HYDRUS-1D, and the results show that the two-site model can well simulate the reactive transport of Cr(VI). This study may provide a useful reference for the remediation of groundwater contaminated with Cr(VI) or other similar heavy metals using FP-nZVI.
