Summary: This study assessed the toxic effects of the broad-spectrum triazole fungicide prothioconazole (PTC) and its metabolite prothioconazole-desthio (PTCd) on Daphnia magna. The results showed that both PTC and PTCd had adverse effects on the growth and reproduction of D. magna, with PTC being more toxic than PTCd. Therefore, the environmental risks of these metabolites should not be ignored.

Summary: A quantitative structure-toxicity relationship (QSTR) model based on norm descriptors was established in this study to predict the toxicity of pesticides to Daphnia magna. The model showed good predictability, stability, and reliability, indicating that norm descriptors might be universally applicable in describing the relationship between the toxicity and structures of pesticide compounds.

Summary: This study investigated the uptake, acute toxicity, and depuration of ZnO nanoparticles using the model fresh water organism Daphnia magna. The results showed that the toxicity of the nanoparticles depended on their size and the presence of surfactant. Contrary to previous reports, the study did not detect any depuration of ZnO nanoparticles after exposure.

Summary: This study demonstrated the multi-organ toxicity of cylindrospermopsin (CYN) to Daphnia magna through behavioral observation, chemical detection, and transcriptome analysis. CYN inhibits protein synthesis, induces oxidative stress and neurotoxicity, and interferes with energy metabolism in Daphnia magna. Additionally, CYN triggers self-defense responses in Daphnia magna by moderating lipid metabolism and distribution.

Summary: With the widespread use of diethylstilbestrol (DES), it has become a common contaminant in the aquatic environment. It is toxic to a wide range of aquatic organisms, disrupting the water flea growth and further interfering with several ecosystem services. Nevertheless, the molecular mechanism of DES in water fleas is still unexplicit. In this study, the 21-day chronic test showed that a negative effect of growth and reproduction can be observed with DES exposure. Transcriptomic analysis revealed that exposure to DES significantly affects energy metabolism, lipid metabolism, the digestive system, transport, and catabolism pathways in D. magna, leading to reduced body length and delayed first spawning time. Therefore, this study emphasizes the threat of DES to D. magna and provides insights into its molecular mechanism.

Summary: This study investigated the chronic toxicity of the novel pesticide broflanilide on Daphnia magna. The results showed that broflanilide affected the growth, development, reproduction, and offspring development of D. magna. It inhibited the expression of chitinase, ecdysteroid, and related genes, affecting molting. Broflanilide also affected the neurotransmitter function and behavior of D. magna, reducing swimming distance and speed.

Summary: This study investigated the intergenerational toxicity of polystyrene microplastics (PS-MPs) and roxithromycin (ROX) on Daphina magna. The results showed that the carrier effects of aged PS-MPs altered the survival and reproduction of D. magna. The combined exposure of PS-MPs and ROX had a greater impact on the swimming behavior and feeding behavior of D. magna compared to the single exposure. The biochemical biomarkers and time of first brood were identified as the most sensitive indicators for assessing the interaction of emerging contaminants.

Summary: This study reveals that FeAB may induce oxidative stress in Daphnia, inhibiting their antioxidant system. Exposure to low concentrations of FeAB results in higher ROS/RNS levels, indicating antioxidant mechanism failure, while exposure to relatively high concentrations leads to reduced ROS/RNS levels possibly due to decreased production from cell damage.

Summary: The study investigated the single and mixture toxic effects of MC-LR and Phe mixtures on aquatic organisms, with results showing that the mixture toxicity was concentration-dependent and exhibited synergistic effects at low concentrations. The protective effects of high concentrations of MC-LR may lead to antagonistic effects. Furthermore, exposure to low concentrations of the mixture had a greater toxic effect on D. magna than either chemical alone.

Summary: This study provides a combined approach to quantitatively and qualitatively detect the release of nanoplastics in water and measure direct exposure of consumers through simulated use of plastic bottles. The researchers found that mechanical stress alters the physical-chemical characteristics of the generated secondary nanoplastics, degrading their material properties and complicating their chemical identification. Understanding material degradation processes is crucial for identifying and quantifying nanoplastics in real samples.

Summary: Microplastics (MPs) are an emerging environmental problem that needs careful monitoring. Although MPs have been widely recorded in marine and freshwater ecosystems, there have been few studies on MP occurrence in terrestrial ecosystems. In this study, barn owl pellets were analyzed to assess both barn owl diet and MP content as a non-invasive method for assessing MP contamination in terrestrial ecosystems. The results showed that 33% of the pellets contained MPs, predominantly microfibers. The analysis of barn owl pellets could be a cost-effective method for monitoring MP contamination in terrestrial ecosystems.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
