Summary: This study found that exposure to water soluble synthetic polymers can cause life history changes and altered levels of reactive oxygen species in the freshwater key species D. magna, although acute mortality was not observed. These sublethal effects may result in cascading effects that can impact the entire food web.

Summary: The amount of industrial pollution in the environment and its impact on living organisms is a concern. This study investigated the influence of metal ions in industrial wastewater on Daphnia magna. It was found that the organic content in the wastewater had a positive impact on the survival of D. magna and the range of heavy metal concentrations tolerated by them. The two-stage process of Ca(OH)2 neutralisation followed by sorption with peat effectively removed almost 100% of metal ions from the wastewater.

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: In the study, the acute toxicity of 30 haloquinolines was assessed using Vibrio fischeri, with varying levels of toxicity observed. The presence of larger substituents at the 2/8-positions and less negative charge at the 4/5/6/8-positions in the quinoline derivative rings correlated positively with their toxicity towards V. fischeri.

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: Polyacrylonitrile (PAN) membranes combined with superfine powder activated carbon (S-PAC) have potential applications in water treatment. The composite membranes (PAN/S-PAC) exhibit micro and nanoparticles that interact with diclofenac (DCF) in water, and higher S-PAC concentrations improve water flux and DCF removal efficiency. The study suggests that PAN/S-PAC (3.0) is the optimal composition.

Summary: This study evaluated the removal mechanisms of azo dyes from synthetic textile wastewater using spent mushroom substrate (SMS). The simultaneous adsorption and enzymatic degradation were analyzed. The effect of pH, SMS concentration and temperature were studied. The maximum enzymatic degradation (16.36%) was obtained at pH 4 and 65 g SMS L-1, whereas the maximum adsorption (62.86%) at pH 8 and 155 g SMS L-1, both at 25 degrees C. The simultaneous enzymatic degradation and adsorption led to the removal of 75.67%. with increased color change. The kinetic study showed that dye adsorption was obtained in the first 30 minutes while the enzymatic degradation increased slowly over the time. The treatment with SMS resulted in the removal of 28.75% of the true color and no increase of effluent toxicity.

Summary: This article reviews the potential of hydrothermal carbonization (HTC) as a route for waste biomass valorization, emphasizing the characterization and environmental utilization of hydrochar and its biorefinery potential. HTC and co-hydrothermal carbonization (Co-HTC) can be applied to crop and forestry residues and sewage sludge, providing high hydrochar yields under specific process conditions. The physicochemical properties of hydrochar, determined by different techniques, are crucial in defining its best applications, including pollutant removal, soil improvement, atmospheric pollutant adsorption, energy carrier, and carbon sequestration.

Summary: The aim of this study was to investigate the chronic toxicity of three pesticides (IMI, CLO, and FIP) on the soil insect Folsomia candida, both as single exposures and binary mixtures. The study found that the individual pesticides reduced reproduction, but the mixtures had a weaker effect. Data on the toxic effects of IMI in a mixture with other seed dressing insecticides provides useful information for environmental risk assessors, reducing uncertainties about the ecological risk of pesticide exposure and enabling the use of multiple insecticides in soil management.

Summary: Waste valorization is crucial for a circular bioeconomy, and finding suitable processes to utilize different wastes for energy, chemicals, and materials is necessary. This study proposed a new approach called Co-HTC, which involves co-hydrothermal carbonization of pine residual sawdust and non-dewatered sewage sludge, without adding extra water. The hydrochar produced through this approach showed high fuel ratio, heating value, and nutrient retention, making it a promising option for managing lignocellulosic wastes and sewage sludges.
