“…Although there are few studies on the toxicity of 2D-like materials [ 18 ], except for graphene and graphene oxide, which are the most widely studied [ 19 ], the scientific literature abounds on the consequences of the toxicity of nanoparticles (NPs) [ 20 , 21 ]. For example, titanium dioxide (TiO 2 ) NPs have shown delayed reproduction in aquatic organisms [ 22 , 23 ], cerium dioxide (CeO 2 ) NPs have generated genotoxicological damage in the DNA strands of D. magna and C. riparius [ 24 ], and phosphorus has induced both genotoxic and morphological damage in zebrafish [ 25 ].…”

In this work, the synthesis and structural, thermal, vibrational, morphological, and electronic characterization of 2D-like pure graphene oxide (GO) and phosphorus-containing graphene oxide (GOP) sheets were investigated. The average thicknesses of GO and GOP were 0.8 μm and 3.1 μm, respectively. The electron energy-loss spectroscopy spectra were used to analyze the differences in the C-K and O-K energy edge bands between GO and GOP. In addition, colloidal stability was studied using dynamic light scattering and zeta potential physicochemical techniques, determining that as the concentration increases, the hydrodynamic diameter and electrostatic stability of GO and GOP increase. The colloidal stability was quite important to ensure the interaction between the suspended solid phase and the biomarker. The 2D-like materials were used to determine their ecotoxicological properties, such as the medium lethal concentration, a crucial parameter for understanding ecotoxicity. Acute ecotoxicity experiments (24 h) were conducted in triplicate to obtain robust statistics, with corresponding mean lethal concentration (LC50) of 11.4 mg L−1 and 9.8 mg L−1 for GO and GOP, respectively. The morphological parameters of GO and GOP were compared with a negative control. However, only the case of GO was analyzed, since the Daphnia magna (D. magna) set exposed to GOP died before completing the time required for morphological analysis. The results indicate that the GOP sample is more toxic than the GO, both during and after exposure. Furthermore, the morphological parameters with the greatest statistically significant changes (p<0.05) were associated with the heart and body, while the eye and tail showed less significant changes.

“…The behavior and toxicity of NPs in marine media differ from those in freshwater ecosystems [14]. Recent publications show potential effects in different organisms, including long-term effects in Daphnia magna [14,15], as well as alterations at the molecular level [16] in Daphnia magna upon exposure to magnetic r-GO supporting anatase and γ-Fe 2 O 3 NP nanocomposites. Moreover, current research also shows the ecotoxicological effects of copper oxide nanoparticles on amphibians related with the production of reactive oxygen species (ROS) [17].…”

Micro(nano)plastics (MNPs) can be generated from a variety of sources, including the breakdown of larger plastic items, the abrasion of synthetic textiles, and the fragmentation of plastic waste. These particles can become airborne and be transported by wind, potentially leading to their presence in the atmosphere. Due to their widespread applications, ZnO particles at the nanometer range have attractive proprieties that make them appropriate for being combined with polymers, especially PET (polyethylene terephthalate), the most commonly used polymer in the packaging sector. Nevertheless, ZnO NPs have a potential ecotoxicity that could be reflected in PET-ZnO composites reaching the environment in the form of micro(nano)plastics. To assess the potential release of PET-ZnO, as well as the ecotoxicity of ZnO NPs, PET-ZnO and weathered composites were analyzed. The ecotoxicity of PET-ZnO was tested in organisms representing different food-chain levels and compared to ZnO NPs’ ecotoxicity. The composite form contained a stable dispersion of around 3.7% of NPs uniformly scattered in the polymeric matrix. ZnO NPs were toxic to Vibrio fischeri and Brachionus calyciflorus. PET-ZnO did not exhibited any toxicity to the organisms studied, while a moderate level of toxicity was observed for the weathered forms.

“…For this purpose, culture optimization was carried out first. Then, 24 h-LC 50 values were determined for various magnetic nanohybrids and compared to other parent systems in the literature [1,2]. Morphological damage was compared to the negative control for duplicate experiments, and statistical significance was also evaluated.…”
