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: Facultative sewage lagoons are commonly used for domestic wastewater treatment in small communities, but the discharged wastewater often fails to meet standards. Ozonation, injecting ozone into wastewater, has shown potential to improve effluent quality. Studies conducted in two Indigenous communities found significant reductions in ammonia and biochemical oxygen demand (BOD) after ozonation, but the toxicity to freshwater mussels did not decrease. Overall, ozonation of small volumes of wastewater in facultative lagoons may be an effective method for improving wastewater quality.

Summary: This study investigated the acute toxicity and potential ecological risk of wastewater-derived disinfection byproducts (DBPs) on Gobiocypris rarus. The results showed that the toxicity of phenolic DBPs varied depending on the compound and the environmental concentration. Some phenolic DBPs exhibited high ecological risk. Further research is needed to explore the potential harmful effects of these high-risk compounds and implement appropriate measures to mitigate their ecological risk.

Summary: Neonicotinoids are widely used pesticides that cause severe water pollution, with direct photolysis dominating the degradation process under simulated sunlight. The photolysis products of these compounds show different levels of photo-induced toxicity to Vibrio fischeri, affected by factors such as scavenging radicals and dissolved organic matters. Different photolysis pathways and mechanisms were observed for the four neonicotinoids, with reactive oxygen species playing important roles in the process.

Summary: This study investigated the enantiomer-specific stability and acute toxicity of ivabradine to marine bacterium, Vibrio fischeri, as well as its potential mechanism of action. The results showed that S-ivabradine exhibited enantioselective toxicity to the bacterium, causing serious damage to bacterial cells and disrupting enzymatic activity. The primary mechanism of S-ivabradine toxicity was shown to be oxidative stress. These findings emphasize the importance of further eco-toxicological evaluations of S-ivabradine on other aquatic organisms to determine the environmental risk.

Summary: Several studies have shown that effluent discharges can contaminate waterways. However, the impact of chemical pollutants on sediment, especially from an ecotoxicological perspective, is not well understood. This study compared water-sediment samples from high-anthropogenic urban areas and low-anthropogenic peri-urban areas. The results suggest chronic toxicity effects in the samples collected from the high-anthropogenic urban area, while no acute toxicity was observed in both areas.

Summary: UV/chlorine treatment is efficient for the removal of micropollutants, but can lead to increased formation of disinfection by-products (DBPs) and toxicity alteration. This study investigated effluent organic matter characterization, DBP formation, and toxicity changes after UV/chlorine treatment of wastewater, with a particular focus on the impact of ammonia and bromide. The results showed that UV/chlorine treatment increased the formation of certain DBPs, while post-chlorination further increased the toxicity. However, the acute toxicity to Vibrio fischeri and genotoxicity determined by the umu test decreased after UV/chlorine treatment. Additional ammonia decreased the formation of DBPs, but increased genotoxicity. The addition of bromide dramatically increased brominated DBP formation and overall toxicity, but also reduced acute toxicity and genotoxicity.

Summary: In this study, a qualitative screening of organic micropollutants was conducted in a municipal wastewater treatment plant using gas chromatography-mass spectrometry. The identified compounds were prioritized based on their comprehensive scores, and their individual and joint toxicity were determined using a bioluminescence inhibition assay. The results showed that different organic pollutants had different acute toxicity on the tested bacteria, and the prediction of mixed toxicity could be improved by applying different prediction models. This study provides a theoretical basis for the systematic screening and toxicity prediction of pollutants in wastewater.

Summary: This study proposes a novel configuration of a bench scale spinning adsorber submerged filter, which has good adsorption performance and can operate continuously. By using different particle sizes of activated carbon as adsorbents, wastewater contaminants, such as azorubine, can be effectively removed. For a specific spinning rectangular prism adsorber prototype, operating at a certain rotational speed and adsorbent concentration, it achieves similar removal rates compared to the use of free moving adsorbents.

Summary: Agricultural intensification has negative impacts on the environment, so it is important to introduce crop diversification strategies and alternative management practices to redesign these systems. The Horizon 2020 DIVERFARMING project aims to define sustainable and diversified cropping systems with low-input farming practices. Stakeholders in Italy identified the loss of profitability as the most important problem, and recommended practices such as minimum tillage, maintenance of vegetation covers, application of organic matter/manure, use of green manure, integrated pest management, and change of rotations.

Summary: This study investigates the presence of airborne microplastics (MPs) in the lower human airways and finds that the majority of MPs are in the form of microfibers. The average concentration of MPs in bronchoalveolar lavage fluid is 9.18 items/100 mL, with particulate MPs accounting for a small percentage. The average size of MPs is 1.73 mm, and the longest dimension corresponds to a polyacrylic fiber.

The researchers conducted a one-year monitoring in ten urban areas in Spain to quantify the atmospheric MP deposition. The results showed that polyester fibers were the most abundant type of MPs, and densely populated areas had higher deposition rates. This study provides a systematic methodology for monitoring atmospheric MP deposition.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
