“…The release of engineered NMs may be due to their discharge after applications or during the applied process or through direct emission during their manufacturing. NMs enter the environment mainly through (treated) wastewater, sewage sludge, and waste incineration (Buzea et al 2007;Ding et al 2022;Gottschalk and Nowack 2011). Based on model simulations, the predicted environmental concentration (PEC) of nanomaterials could reach the range of ng-μg/L in surface waters (Wagner et al 2014).…”

Nanomaterials (NMs) are able to interact with natural organic matter (NOM) such that NOM is adsorbed on the surface of NMs to form an ecological corona (eco-corona). The formation of an eco-corona can greatly influence the behavior, risk and fate of NMs in the environment. A systematic understanding of the impacts of an eco-corona on the hazards of NMs is crucial for NMs risk assessment in the aquatic environment. Herein, the mechanisms of the formation of an eco-corona were reviewed based on the representative literatures and their generality was discussed on the basis of the type of NMs, the type of NOM and the environmental conditions. The effects of an eco-corona on the bioaccumulation and toxicity of NMs for aquatic organisms were systematically discussed through reported studies. The results showed that an eco-corona could alter the toxicity of NMs by changing the dissolution of NMs, adhesion of NMs and the damages to bio-membranes, internalization, and the generation of NMs-induced reactive oxygen species. The dual effects of an eco-corona on the toxicity/accumulation of NMs were widely present because of the complex molecular composition of NOM, the diverse types of NMs, and the variable environmental conditions. The effects of an eco-corona on the fate and the effects of other pollutants (such as metals and organic pollutants) were also carefully reviewed. The results showed that more research is needed to investigate the effect of an eco-corona through the development of novel techniques, mathematical modeling, and mesocosm studies.

“…Therefore, it is vital to prevent the absorption of Cl by any of the numerous substrates such as organic matter, ferrous ions, ammonia, hydrogen sulfide, and nitrites. Usually, organic elements mitigate the harmful effects of chlorinated chemicals, which represent short-term dangers to plants and soils ( Ding et al 2022 ).…”

“…The primary redox-reactive moieties on these carbon materials should be similar to pyrogenic carbon (e.g., phenolic and quinone moieties); however, they usually exhibit higher reactivity, a large surface area, rich active sites, small particle size, and wellformed graphitic structure, thereby significantly influencing the transformation of PTEs (Wang et al 2020a). The aging process also has a critical impact on the redox performance of the anthropogenic carbon materials, and it is a combined process involving oxidation, aggregation, and fragmentation (Ding et al 2022a;Park et al 2016), leading to different performances in the redox-induced transformation of PTEs.…”

Soil organic carbon (SOC) is a crucial component that significantly affects the soil fertility, soil remediation, and carbon sequestration. Here, we review the redox-induced transformation of potentially toxic elements (PTEs) through the abiotic impact of SOC. The complex composition of SOC includes humus, pyrogenic carbon (e.g., biochar), dissolved organic matter, and anthropogenic carbon (e.g., compost), with varying concentrations and properties. The primary redox moieties on organic carbon are surface functionalities (e.g., phenol, quinone, and N/S-containing functional groups), environmentally persistent free radicals, and graphitic structures, and their contents are highly variable. Owing to these rich redox moieties, organic carbon can directly affect the reduction and oxidation of PTEs in the soil, such as Cr(VI) reduction and As(III) oxidation. In addition, the interactions between organic carbon and soil redox moieties (i.e., O2, Fe, and Mn minerals) cause the transformation of PTEs. The formation of reactive oxygen species, Fe(II), and Mn(III)/Mn(II) is the main contributor to the redox-induced transformation of PTEs, including Cr(VI) reduction and As(III)/Cr(III)/Tl(I) oxidation. We articulated both the positive and negative effects of organic carbon on the redox-induced transformation of PTEs, which could guide soil remediation efforts. Further scientific studies are necessary to better understand the potential transformations of PTEs by SOC, considering the complicated soil moieties, variable organic carbon composition, and both biotic and abiotic transformations of PTEs in the environment.
