Summary: Both BPA and PSNPs are commonly found in consumer products and pose serious threats to the environment and aquatic life. This study examined the toxic effects of PS-NPs and BPA on the microalgae Scenedesmus obliquus, as well as the impact of algal EPS on their interaction. The results showed that EPS-containing mixtures reduced toxicity by decreasing reactive oxygen species levels, antioxidant enzyme activity, and cell membrane damage, leading to improved photosynthetic pigment content in the cells.

Summary: The application of nanomaterials in agriculture has seen extensive exploration in the past decade, resulting in a wide range of nanoparticle-based agrochemicals. Metallic nanoparticles composed of plant macro- and micronutrients have been used as nutritional supplements for plants through various methods. However, most studies have focused on monometallic nanoparticles, limiting their usage and effectiveness. In this study, a bimetallic nanoparticle consisting of copper and iron was used in rice plants to test its efficacy in terms of growth and photosynthesis. Experiment results showed that foliar application of 5 mg L-1 bimetallic nanoparticle increased vigor and photosynthetic efficiency, while a concentration of 10 mg L-1 induced oxidative stress to some extent. Furthermore, the bimetallic nanoparticle treatment did not cause structural anomalies or cytotoxicity in the exposed plant parts. This study not only demonstrates the effectiveness of Cu-Fe bimetallic nanoparticles but also critically explores their safety on rice plants, providing valuable insights for designing new bimetallic nanoparticles and exploring their efficacy.

Summary: Disposable surgical face masks used during COVID-19 outbreak release microplastics into water, along with titanium dioxide nanoparticles (nTiO(2)). The leached microplastics from the masks were identified as polypropylene of varying sizes. In addition, heavy metals leached from the masks, combined with nTiO(2), pose a severe environmental threat as they cause cellular damage, decrease photosynthesis, and increase oxidative stress in algae.

Summary: Due to their remarkable properties, the applications of carbon-based nanomaterials (CNMs) such as graphene and functionalized multi-walled carbon nanotubes (f-MWCNTs) are increasing. These CNMs can enter the freshwater environment and potentially expose various organisms. The study found that both graphene and f-MWCNTs caused toxic effects on freshwater algae species, including a decrease in cell viability, esterase activity, and photosynthetic efficiency. The binary mixture of the pollutants showed a synergistic enhancement of the toxic potential. Oxidative stress played a critical role in the toxicity responses. The study highlights the importance of considering the combined effects of CNMs in evaluating ecotoxicity in freshwater organisms.

Summary: The unsustainable manufacturing, utilization and inadequate handling of plastics have caused a significant increase in global plastic pollution. There is growing concern about the potential hazards associated with exposure to micro/nanoplastics (M/NPs). Understanding the environmental behavior of M/NPs, particularly in aquatic systems, where they are likely to accumulate, is crucial. The formation of a biocorona (BC) through interaction with biomolecules within aquatic organisms modifies the physicochemical attributes of M/NPs, such as size, stability, and surface charge. This review discusses the concept of BC formation, analytical techniques for characterizing it, and its implications on the toxicity, fate, and transport of M/NPs in the environment.

Summary: Heavy metal-organic complexes are widespread in contaminated waters and pose a greater challenge for decontamination compared to free ions. Current analytical methods are unable to determine these complexes, impeding the development of decontamination mechanisms. A highly sensitive and selective colorimetric sensor for detecting Cr3+/Hg2+-organic complexes using citrate functionalized silver nanoparticles (Ag NPs) has been developed. The sensor exhibits nanomolar scale detection and its application could greatly advance the instant colorimetric detection of heavy metals in the environment.

Summary: This study examines the effects of microplastics and low pH on the physiology and development of Artemia salina through exposure experiments. The results indicate that the combined exposure to microplastics and low pH induces oxidative stress and adversely affects the development of Artemia salina. These findings underscore the need for further research on the combined toxicological impacts of ocean acidification and predominant pollutants like microplastics on other marine animals.

Summary: Due to the escalating risk of plastic pollution, nanoplastics have received significant attention. A study examined the individual and combined effects of fluorescent polystyrene nanoplastics (FNPs) and diclofenac (DCF) on Scenedesmus obliquus. The toxicity of S. obliquus significantly increased upon exposure to DCF and FNPs, with oxidative stress being the major cause. When FNPs and DCF were mixed, a synergistic or antagonistic effect was observed depending on the concentrations. Oxidative stress parameters, antioxidant enzyme activity, and pigment content in the algae validated the cytotoxicity data. The study highlights the hazardous nature of nanoplastics and their co-exposure risks with pharmaceuticals.

Summary: This paper presents a thorough assessment of the toxicity and mechanism of action of micro- and nanoplastics (MNPs) in the bloodstream. MNPs can cause various toxic effects, including plasma protein denaturation, hemolysis, reduced immunity, thrombosis, and vascular endothelial damage, among others, which can lead to life-threatening diseases. The key mechanisms of toxicity include protein corona formation, oxidative stress, cytokine alterations, inflammation, and cyto- and genotoxicity. There are research gaps regarding the combined toxicity of MNPs and co-pollutants, real-world MNPs toxic impacts, bioaccumulation, dose-response relationships, and the effect of different physiochemical characteristics of MNPs.
