Summary: This study proposes a microplate assay for chemical toxicity evaluation using S. natans,based on the culture dish assay. The feasibility of the microplate assay was evaluated by exposing S. natans to model chemicals, and similar toxicity sensitivity results were found compared to the culture dish assay. The microplate assay is a simple and effective method for assessing ecotoxicity.

Summary: Pollution of water bodies by metals remains a threat to ecosystems, and a study examined the effects of six metals on the benthic species Closterium ehrenbergii. The study found that these benthic algae may be more sensitive to metal toxicity compared to standard planktonic species. The toxicity of the metals ranked in descending order from highest to lowest were Cu, Ag, Cd, Ni, Cr, and Zn. This study suggests that C. ehrenbergii can be a valuable addition to ecotoxicological risk assessment.

Summary: Ozonation is a viable option to improve the removal of micropollutants (MPs) in wastewater treatment plants (WWTPs). This study investigated a combination of biological activated carbon (BAC) filtration followed by ozonation (the BO3 process) to remove MPs at low ozone doses and low energy input, and focused on the formation of toxic transformation products during ozonation.

Summary: The textile industry in Tunisia is a major economic sector, but it poses potential risks to the environment and human health due to the generation of toxic wastewater. The study revealed that certain physicochemical parameters and metals in textile dyeing effluents did not meet Tunisian standards, and high quantities of dyes were detected even after treatment. Ecotoxicological assessments showed toxic effects on test organisms, particularly Selenastrum capricornutum, indicating potential risks to aquatic biota.

Summary: The lethal toxicity of Shibukuro and Tama river water near the inflow of Tamagawa hot-spring water in Akita Prefecture, Japan was investigated. Metal concentrations in both rivers were measured, with iron, arsenic, and aluminum detected. The toxicity of the river water had a negative effect on aquatic organisms, with water flea Daphnia magna being more sensitive to the toxicity than zebrafish Danio rerio. The toxic effects decreased with increasing distance downstream from the inflow of hot-spring water.

Summary: This study presents a rapid, sensitive, and cost-effective method for detecting TPHs using Aliivibrio fischeri bioluminescence inhibition bioassay. The optimal conditions for A. fischeri growth were determined, and both short-term and long-term toxicity assays were conducted. The results showed that the best time for bacterial growth was 16 hours after inoculation, and the optimal temperature and pH were 25 degrees Celsius and 7, respectively. The long-term assay returned results after 6 hours, with an EC50 of 1.77 mg/L for TPHs.

Summary: This study investigated the influence of calcium particles from eggshell residues on the anaerobic digestion of cassava wastewater (CW) and remotely monitored the performance of the bioreactor. The results showed that adding calcium particles significantly increased biogas production. Furthermore, post-treatment of the digestate is necessary to avoid phytotoxicity before its use as agricultural fertilizer.

Summary: This study aimed to develop a new phytotoxicity test using the gametophytes of Undaria pinnatifida to evaluate the effects of commonly used antifouling chemicals on seaweeds. The toxicity of Cybutryne, Diuron, Cu2+, and Zn2+ to the gametophytes was assessed by measuring the relative growth rate at the logarithmic growth phase. The test method showed high sensitivity and reproducibility, making it a valuable addition to routine toxicity evaluation of hazardous chemicals.

Summary: Environmental conditions in aquatic ecosystems play a significant role in transforming toxic chemicals, such as copper nanoparticles, and influencing their bioavailability and toxicity. This study investigated the accumulation and toxicity of aged nano-Cu in marine phytoplankton, and found that the dissolution rate of nano-Cu decreased during the first 4 weeks before increasing rapidly after 15 weeks. The toxicity of nano-Cu to phytoplankton decreased with particle aging from 0 to 4 weeks, but increased significantly after 15 weeks due to elevated Cu dissolution.

Summary: The study found that tropical seagrass seedlings exhibited stronger responses to rising temperatures compared to increased CO2 concentrations. The effects of increased temperature included enhanced leaf growth, lower leaf nutrient content, and stimulated down-regulating mechanisms in terms of photo-physiology.

Summary: Competitive interactions among tropical seagrass species are driven by resource competition, with different species exhibiting varying probabilities of space preemption. Plant size plays a key role in determining the likelihood of a species to preempt space, with larger species having higher probabilities. Additionally, competitive interactions among seagrass species are asymmetrical, with negative effects not being reciprocal.

Summary: This study examined the trait responses of tropical seagrass species Cymodocea serrulata under experimental conditions of seawater acidification and high temperature. The results showed that the trait responses were limited, challenging the hypothesis that ocean acidification can help seagrasses cope with higher temperatures. Understanding species-specific trait responses is crucial for conservation efforts and management decision-making.

Summary: Wetland plants in blue carbon ecosystems play a crucial role in climate change mitigation, but they are facing threats from both local and global stresses. The ability of these ecosystems to store carbon relies on plant traits that are shaped by the stresses they encounter. This manuscript investigates the effects of stress on carbon storage and sequestration in blue carbon ecosystems based on plant traits, evaluates existing knowledge on stress effects, and discusses the application of a trait-based approach to understand and predict carbon dynamics under different stress feedbacks. The conclusions highlight the importance of embracing the trinomial relationship between local and global stresses, plant traits, and blue carbon, and emphasize the need for plant trait standardization.

Summary: This study investigated the impact of upwelling intensity on the trophic dynamics of mesozooplankton in a coastal system. The findings suggest that upwelling events lead to increased herbivory and a shorter, more efficient food web structure. The contribution of microbes to the food web was highest at low-moderate upwelling intensities and decreased during downwelling or strong upwelling events.
