Summary: Engineered nanomaterials (ENMs) are a novel class of materials with superior physicochemical properties compared to conventional materials, but can potentially release into the environment and pose toxic effects. Research focuses on the transformations and potential risks of ENMs in consumer products, aiming to ensure their safe application.

Summary: Humans are widely exposed to a great variety of mycotoxins and their mixtures, so it is important to prioritize mycotoxins based on their toxic potential. A strategy combining in silico tools and in vitro tests was used to classify 12 mycotoxins and evaluate their mutagenic potential, showing different mutagenic potentials and the role of metabolic activation in some mycotoxins.

Summary: The study confirmed the suitability of salivary leucocytes as a biological sample for in vitro nanogenotoxicity studies, and demonstrated an increase in DNA damage caused by metal oxide NPs. These findings contribute to a better understanding of the impact of NPs on human health, highlighting the need for specific regulation in the use of nanomaterials.

Summary: The increase in the number of products containing nanoparticles (NPs) poses a real threat to the environment. Although the acute toxicity of most aquatic NPs has been well documented, there is relatively little research on the long-term effects of NPs on the reproductive system and gamete quality of aquatic organisms. In an experiment on the sand dollar, exposure to copper oxide nanoparticles (CuO NPs) resulted in copper accumulation in tissues, increased lipid peroxidation product concentrations, decreased fertilization rate, and increased sperm DNA damage.

Summary: A new material composed of kaolin base with silver nanoparticles was developed as an alternative to antibiotics in animal feed. In an in vivo geno-toxicological evaluation in rats, the material showed no adverse effects when administered orally at a dose of 2000 mg/kg b.w. for 28 days. The material did not induce micronuclei or DNA damage in various tissues, and silver content in target organs confirmed the negative results.

Summary: Nanocomposites, such as metal nanoparticles, are widely used in biomedical applications, including drug delivery systems. Green nanocomposites made of biocompatible and biodegradable nanoparticles are considered safer options. However, concerns about the potential health risks, including DNA damage, due to the enhanced reactivity of metal nanoparticles have led to the development of the Comet Assay for genotoxicity assessment. This assay plays a crucial role in evaluating the safety and efficacy of metal nanoparticles in drug delivery systems.

Summary: In this study, self-assembled bovine serum albumin nanoparticles loaded with genistein were PEGylated to avoid possible immunogenic reactions and rapid clearance from the bloodstream. The PEGylation process increased the particle size of the nanoparticles and improved their biological properties, reducing cytotoxicity and genotoxicity.

Summary: Diverse industries have incorporated engineered nanoparticles (ENP) into their production processes, increasing the risk of worker inhalation exposure. In vitro models, particularly using air-liquid interface (ALI) cell cultures, are valuable for studying ENP toxicity. When comparing submerged and ALI conditions for ENP exposure, it was found that ALI cultures were more sensitive to the cytotoxic effects of ENP on human alveolar epithelial-like cells.

Summary: In recent years, the genotoxicity of graphene-related materials (GRMs) and other 2D materials has been evaluated using different models. The OECD TG 487 in vitro micronucleus (MNu) test is commonly used to assess the genotoxicity of nanomaterials (NMs). However, the nature of NMs interferes with the standard MNu process, requiring adaptations. The study proposes a modified in vitro MNu test with improvements to accurately test the genotoxicity of NMs, demonstrating risks associated with graphene oxide (GO) and boron nitride (hBN).

Summary: The study found that Cu-65 enriched CuO nanoparticles fed to fish resulted in significant amounts of Cu-65 in the feces, but no significant accumulation of Cu-65 in internal organs, except for a slight elevation in the liver. Gene expression analysis showed only metallothionein was significantly upregulated in intestinal tissue, while other genes remained unchanged. Overall, the results suggest limited dietary absorption efficiency of CuO NPs and minimal effects on Cu-related genes at low environmentally relevant exposure doses.

Summary: Tracer tests are a well-established method for delineating key environmental processes, and this study provides ecotoxicity data for Rhodamine B and WT, showing that Rhodamine B is more toxic than Rhodamine WT. Therefore, read-across assessments using ecotoxicity data obtained with Rhodamine B is not advisable for estimating the ecotoxicity of Rhodamine WT.

Summary: This paper presents a further development and testing of an environmental risk screening method based on two proxy measures: aquatic ecotoxicity and global annual production volumes. The results show that only MXenes exhibit high aquatic ecotoxicity, while the other materials should continue to be monitored for their aquatic ecotoxicity data.

Summary: This study presents two complementary approaches to account for shading in algal growth inhibition tests of engineered nanomaterials (ENMs) and colored substances. The first approach distinguishes between shading effects and toxicity, while the second approach addresses shading at the cellular level. The results indicate that toxicity rather than cellular shading dominates the response of algae exposed to ENMs.

Summary: The European Union has revised its chemical legislation to clarify technical data requirements for nanomaterials, with new provisions coming into effect from January 1, 2020. The study found that most of the information requirements and over 40% of the waiving criteria in the new REACH Annexes are supported by available methods. The study recommends further development of methods to fulfill the new regulatory requirements for physico-chemical characterisation and environmental fate and effects of nanomaterials.

Summary: The study found a low bioaccumulation potential of nano-CuPc in freshwater organisms, indicating limited entry from sediment into the benthic food web. Nano-CuPc showed relatively high attachment to algae, but insignificant accumulation in crustaceans and snails after exposure. These results suggest that nano-CuPc mainly remains in water and sediments rather than being bioaccumulated by aquatic organisms.
