“…Graphene and its derivatives may have potentially toxic effects on aquatic organisms after transformation in aquatic environments. The combined action of hypochlorite and visible‐light‐transformed GO reduces the photosynthesis of chlorella, thus inhibiting its growth and reproduction (Wang et al, 2020). Similarly, binary mixtures of RGO and (ZrO2) n , combinations of GO and ionic liquids, GO after 8 days of sunlight conversion, and graphene and its derivatives for adsorption macronutrient in water have been all proven to induce oxidative stress in algae cells, resulting in membrane damage, nutrient depletion, and eventually inhibiting the algae cells' growth (Wang et al, 2017; Wang, Zhang, et al, 2021; Zhao et al, 2020).…”

The purpose of this paper is to explore the current research status, hot topics, and future prospects in the field of graphene and its derivatives toxicity. In the article, the Web of Science Core Collection database was used as the data source, and the Cite-Space and VOSviewer were used to conduct a visual analysis of the last 10 years of research on graphene and its derivatives toxicity. A total of 8573 articles were included, and we analyzed the literature characteristics of the research results in the field of graphene and its derivatives toxicity, as well as the distribution of authors and co-cited authors; the distribution of countries and institutions; the situation of co-cited references; and the distribution of journals and categories. The most prolific countries, institutions, journals, and authors are China, the Chinese Academy of Sciences, RSC Advances, and Wang, Dayong, respectively. The co-cited author with the most citations was Akhavan, Omid. The five research hotspot keywords in the field of graphene and its derivatives toxicity were "nanomaterials," "exposure," "biocompatibility," "adsorption," and "detection." Frontier topics were "facile synthesis," "antibacterial activity," and "carbon dots." Our study provides perspectives for the study of graphene and its derivatives toxicity and yields valuable information and suggestions for the development of graphene and its derivatives toxicity research in the future.

“…It is very elastic and thermally and electrically conductive [ 106 ]. With the benefits of a high specific surface area, strong hydrophilicity, and low toxicity, graphene oxide (GO), a graphene derivative, may efficiently remove heavy metals from wastewater while overcoming the drawbacks of graphene’s hydrophobicity [ 107 ]. GO is decorated with numerous reactive functional groups such as —OH, —COOH, —C = O, and other hydrophilic groups.…”

As highly toxic and carcinogenic substances, antimony and arsenic often coexist and cause compound pollution. Heavy metal pollution in water significantly threatens human health and the ecological environment. This article elaborates on the sources and hazards of compound antimony and arsenic contamination and systematically discusses the research progress of treatment technology to remove antimony and arsenic in water. Due to the advantages of simple operation, high removal efficiency, low economic cost, and renewable solid and sustainable utilization, adsorption technology for removing antimony and arsenic from sewage stand out among many treatment technologies. The adsorption performance of adsorbent materials is the key to removing antimony and arsenic in water. Therefore, this article focused on summarizing frontier adsorption materials’ characteristics, adsorption mechanism, and performance, including MOFs, COFs, graphene, and biomass materials. Then, the research and application progress of antimony and arsenic removal by frontier materials were described. The adsorption effects of various frontier adsorption materials were objectively analyzed and comparatively evaluated. Finally, the characteristics, advantages, and disadvantages of various frontier adsorption materials in removing antimony and arsenic from water were summarized to provide ideas for improving and innovating adsorption materials for water pollution treatment.

“…Apesar desse resultado positivo em termos de mitigação de toxicidade, ainda é obrigatório avaliar os efeitos toxicológicos de materiais à base de óxido de grafeno tratados com NaClO usando outros sistemas biológicos para abordagens integradas para avaliação de toxicidade e gerenciamento de risco. Atenção especial tem sido dada a essa necessidade, por exemplo, recentemente, esses materiais degradados mostraram efeitos deletérios contra algas (Chlorella vulgaris) (WANG et al, 2020). Wu et al (2014a) sugerem que o óxido de grafeno em C. elegans, após exposição prolongada de larvas L1 a adultos, pode ser transferido para órgãos-alvo primários (faringe, intestino e reto) e causar danos às funções normais desses órgãos.…”
