Summary: The production of plastic waste has significantly increased, resulting in the release of millions of tons of plastic waste into the environment annually. This waste can break down into smaller micro- and nanoplastics (MNPs), which are toxic to organisms and pose risks to aquatic ecosystems, food chains, and human health. This review provides a comprehensive assessment of the (eco)toxicity of MNPs on aquatic algae, highlighting the significant risks they pose to essential ecosystems and human health.

Summary: Plastic contamination in the environment is a major concern and assessing the risk of micro-and nanoplastics is challenging. This study collected and analyzed toxicity data of polystyrene micro- and nanospheres in various organisms, finding that aquatic invertebrates were the most studied, nanosized PS was more frequently studied, acute exposures were more prevalent than chronic exposures, and 40% of the data showed no effects of PS on organisms. Future studies should focus on environmentally relevant plastics concentrations, wide range of organisms, co-exposures with other pollutants, and method development for plastics identification and quantification.

Summary: The study found that propofol has longer induction and anesthesia duration compared to eugenol in fish anesthesia, while also having a faster recovery rate. In terms of hematological indices, the propofol group showed a transient increase compared to the eugenol group. However, there were no significant changes in other indicators such as leukocytic counts between the two groups. During anesthesia, both propofol and eugenol groups showed a temporary increase in glucose and cortisol levels, which returned to baseline levels during the recovery period.

Summary: This study investigated the toxicity of perfluorooctane sulfonate (PFOS) and virgin yellow-green fluorescent polystyrene nanoparticles (NPs) on marine mussels. The results showed that co-exposure of PFOS and NPs significantly increased the distribution of PFOS in mussel tissues and elevated the levels of reactive oxygen species (ROS). The study also found altered responses of antioxidant entities and downregulated expressions of oxidative stress-related genes. The findings suggest that NPs can influence the distribution of PFOS between mussels and seawater.

Summary: In this study, it was found that ATP1A1 may be a key susceptibility gene involved in calcium stone formation. The down-regulation of ATP1A1 was associated with crystal deposition and activation of related signaling pathways. Overexpression of ATP1A1 or treatment with a specific inhibitor alleviated oxidative stress, inflammation, apoptosis, crystal-cell adhesion, and stone formation. These findings suggest that ATP1A1 could be a potential therapeutic target for treating calcium stones.

Summary: With the increase in global food demand, agricultural practices and pesticide applications are on the rise. Nanotechnology-based pesticides, known as nanopesticides, have gained importance due to their higher efficiency and, in some cases, lower toxicity compared to conventional pesticides. However, there are concerns about their (eco)safety as evidence on their environmental impact is controversial. This review aims to provide an overview of the current nanotechnology-based pesticides, their toxic mechanisms, their fate in the environment (particularly aquatic environments), and the available research on their ecotoxicological effects on non-target organisms. The review also highlights the need for more comprehensive studies on the fate and ecotoxicity of nanopesticides and identifies research gaps in this area.

Summary: Heat shock proteins (HSPs) are molecular chaperones and stress proteins that are expressed in response to various stresses. They play a vital role in regulating protein synthesis, folding, and assembly in cells. HSPs also influence apoptosis, the immune system, and inflammation. In aquatic organisms, increasing HSP levels through non-traumatic methods can provide health benefits and improve husbandry practices. This review discusses the importance of HSPs in different tissues in aquatic organisms and their expression during pathogen invasion.

Summary: Graphitic carbon nitride (g-C3N4) and CuO nanoparticles doped g-C3N4 (Cu-g-C3N4) exhibit high photocatalytic antialgal activities against harmful algae, with Cu-g-C3N4 showing stronger activity due to better aggregation and higher light utilization efficiency. The presence of humic acid (HA) inhibits the antialgal activity of g-C3N4 but has no effect on Cu-g-C3N4, suggesting that CuO nanoparticles in Cu-g-C3N4 play a role in mitigating the inhibition effects of HA. This study provides insights into the inhibition mechanisms of natural organic matter on g-C3N4 photocatalytic antialgal activity and optimization strategies for environmental applications.

Summary: The combination of silicon (Si) and melatonin (MT) was found to be more effective in reducing the uptake and transport of cadmium (Cd) and arsenic (As) in rice plants compared to Si alone. The Si+MT treatment significantly decreased Cd and As concentrations in rice grains, with the greatest impact seen in high-polluted soil (HP) for Cd reduction and in low-polluted soil (LP) for As reduction. This effect may be attributed to the regulation of antioxidant potential and gene expression related to Cd uptake and transport.

Summary: Ball-milled biochar (BMBC) is an engineering material with potential applications in remediating contaminated soil and water. This study investigated the effects of ubiquitous cations and model organic matter on the transport of BMBC using laboratory column experiments. The results showed that humic acid facilitated the transport of BMBC under neutral conditions, while ionic strength and humic acid had antagonistic effects on BMBC transport. Additionally, the presence of Mg2+ and Al3+ resulted in charge reversal of the BMBC surface, affecting deposition and transport.

Summary: In this study, iron-enriched sludge-derived hydrochar was prepared as a high-efficiency catalyst for the oxidation of triclosan. The hydrochar exhibited excellent removal efficiency of triclosan, with a broad pH applicability and great recycling stability. The activation of H2O2 was achieved by both persistent free radicals and iron, making the degradation efficiency significantly higher than that of the conventional Fenton reaction. These findings provide insights into the utilization of iron-enriched sludge and the role of hydrochar in promoting iron cycling and electron transfer in the Fenton reaction.

Summary: We synthesized novel Se-doped carbon quantum dots and compared two different Se-doping methods in their ability to deliver Se to tomatoes and promote plant growth and development. The samples synthesized via the co-cracking method showed better performance in increasing plant biomass, mineral content, fruit quality, and Se accumulation. This could be attributed to their smaller size and less negative charge, which facilitated better penetration and transport in plant tissues. The slower release of Se from these samples during foliar application also contributed to their higher efficiency as a potential Se nano-carrier.

Summary: The pyrolysis of biomass containing excessive heavy metals can result in heavy metal contaminated biochar (BC). In addition to higher charring temperature, particle size of BC also plays a critical role in the content of heavy metals and its ecotoxicity. Content and chemical forms of cadmium (Cd) in BC fractions as well as the related algal toxicity were examined. The results showed that particle size significantly modified the chemical forms and ecotoxicity of Cd in BC, which has important implications for understanding the behavior and potential risk of heavy metal contaminated BC in the environment.

Summary: Graphitic carbon-doped alpha-Bi2O3/beta-Bi2O3/Bi5O7I ternary heterojunction photocatalysts were successfully synthesized via a simple and low-cost method using urea, malonic acid, and BiOIO3. The photocatalytic activity of the catalysts was evaluated by the degradation of Bisphenol A (BPA) under simulated sunlight irradiation. The graphitic carbon-doped alpha-Bi2O3/beta-Bi2O3/Bi5O7I photocatalysts exhibited significantly higher reaction rate constants compared to other catalysts, thanks to the synergistic effect of the heterojunction between different components and the efficient electron transfer efficiency of graphitic carbon. A dual S -scheme heterojunction mechanism was proposed to explain the excellent redox properties of the composites.
