Summary: This study investigated the toxic effects of tire microplastics and their additives on zebrafish using theoretical chemical calculation methods. The results showed that styrene butadiene rubber had the most significant toxic effect on zebrafish. Adjusting the ratio of rubber additives could alleviate the toxic effects of styrene butadiene rubber on marine and freshwater organisms.

Summary: In this study, palladium-doped polystyrene NPLs (PS-NPLs) with irregular surface morphology were used to assess their toxicity on cyanobacterium, green algae, and crustacean. The EC50 concentration for D. magna was 49 mg NPLs/L, while for C. reinhardtii it was 248 mg NPLs/L. PS-NPLs induced reactive oxygen species overproduction, membrane damage, and metabolic alterations in a dose-dependent manner. The distribution of PS-NPLs under static and stirring conditions was studied to understand their environmental fate.

Summary: The study revealed that adapting freshwater Anammox bacteria to saline environments can efficiently remove inorganic nitrogen. During the salt adaptation process, significant changes in microbial communities were observed, and the evolution from low salt-tolerance species to high salt-tolerance species is crucial for the recovery of Anammox activity.

Summary: This study investigated the acute toxicity of two common mycotoxins, deoxynivalenol (DON) and zearalenone (ZON), on a variety of freshwater organisms. The results showed that crustaceans were the most sensitive to DON, while cnidarians and molluscs were more sensitive to ZON. Combining these novel invertebrate toxicity results provides valuable information for the analysis of Species Sensitivity Distributions.

Summary: With the ban on BFRs, OPFRs have been used as substitutes, but one common OPFR, TCEP, has been found in various environmental compartments. This study used bibliometrics analysis and meta-data analysis to assess the risk of TCEP to aquatic life, finding toxicity and environmental concentration as research hot spots. The study emphasizes the ecological risk of TCEP to freshwater organisms and provides important data support for risk assessment and environmental management.

Summary: Plastic, a ubiquitous material globally used, can cause ecotoxicological consequences, with polymers like polyethylene, polypropylene, and polystyrene being commonly ingested by marine organisms, along with hazardous chemicals such as persistent organic pollutants (POPs). The research suggests that plastic serves more as a sink for non-additive pollutants rather than a vector.

Summary: Plastic pollution has become a global emergency concern and the degradation processes of plastic waste at different scales is well-documented. The use of worms as model species for investigating micro(nano)plastic pollution in aquatic systems is discussed in this review. The relevance of laboratory studies and field investigations, as well as recommendations for future studies, are also analyzed and presented.

Summary: Cigarette butts (CBs) are a common form of litter on beaches and represent an unexplored environmental threat. This study investigated the toxicological risks of CBs on marine organisms through chemical analyses and a variety of biological responses. The results showed that CBs released trace metals, hydrocarbons, nicotine, and cotinine, which significantly impacted bacterial bioluminescence, oyster embryo development, and algal growth. Laboratory experiments on mussels exposed to CBs also revealed accumulation of chemicals and significant alterations in immune, antioxidant, and neurotoxic responses.

Summary: The chronic toxicity of shale gas flowback wastewater to freshwater biota was assessed using direct toxicity assessment (DTA) in the Beetaloo Sub-basin, Northern Territory, Australia. The results showed that the wastewater was chronically toxic to eight species, with salinity and unidentified chemicals and interaction effects being the main contributors. Safe dilutions for the wastewater were derived using a species sensitivity distribution, providing long-term protection to aquatic biota in case of accidental spills or seepage.

Summary: This study investigates the intensity and spatial patterns of sediment contamination and the potential for ecosystem recovery in three lakes near an abandoned lead and zinc mine in Sweden. The results indicate that the lakes were affected by mining activities, but the extent and timing of the impact varied between lakes. The study emphasizes the importance of considering spatial heterogeneity and hydrological connectivity in risk assessments of mining-impacted lakes and recommends the use of normalized Probable Effect Concentration Quotient (PEC-Q) in toxic assessments.

Summary: This study found no significant effects of tire rubber particles on the growth, survival, or reproduction of freshwater sediment dwellers Lumbriculus variegatus and Chironomus riparius in laboratory experiments. Although differences were observed among animals dwelling on different sediments, these effects were not attributed to the presence of tire rubber particles. The potential impacts of tire rubber particles in the real environment with longer durations and varying environmental factors should be further investigated, including considering the influence of factors such as the leaching of additives on the overall toxicity of tire rubber particles.

Summary: This study identified the priority control sequence of pollutants in wastewater treatment plant effluents by considering their occurrence frequency, concentration, removal rate, and in vitro and in vivo toxicity. The top 5 pollutants were found to be ethynyl estradiol, 17β-estradiol, estrone, diclofenac, and atrazine. In addition, the synergistic effects between pollutants were also evaluated, and pollutants like ofloxacin and acetaminophen were found to have significant interactions with other pollutants. This study sheds new light on the management and control of wastewater water quality.

Summary: Currently, conventional biological nitrogen removal processes face challenges in removing ammonium from saline wastewater. This study successfully utilized marine anammox bacteria in a microbial electrolytic cell to convert NH4+-N to N2. In addition, the application of voltage increased microbial diversities at the electrode surface and promoted the formation of electrode biofilm.

Summary: The study aimed to review and estimate the correction factors (CFs) for atenolol, carbamazepine, and naproxen in wastewater-based epidemiology (WBE) using data from Australia. The estimated CFs for atenolol and carbamazepine were found to be 1.37 and 8.69, respectively. Due to over-the-counter sales of naproxen, a reliable CF could not be estimated based on prescription statistics.

Summary: The study compared the in vitro and in vivo toxicity of cyclic DBPs and aliphatic DBPs, revealing different toxicity rank orders with application of different endpoints. A Pearson correlation analysis of DBP toxicity data showed high correlation between observed cytotoxicity in Hep G2 cells and zebrafish embryo toxicity with previously reported in vitro and in vivo toxicity. The study also established two QSAR models to interpret the toxicity mechanisms of DBPs from different endpoints.

Summary: A recent study found that aromatic DBP fractions are the main contributors to the toxicity of chlorinated drinking water. However, the key drivers of toxicity based on the formation of aliphatic and aromatic DBPs in drinking water have not been comprehensively evaluated. This study explored the occurrence of various aliphatic and aromatic DBPs in drinking water samples from a Chinese megacity. The findings suggest that haloacetonitriles and halonitrophenols are the main toxicity drivers among the measured aliphatic and aromatic DBPs, respectively.

Summary: This study reports the effective degradation of halogenated aromatic disinfection byproducts (DBPs) by ZVI/Cu and establishes a novel mechanism-based quantitative structure-activity relationship model to predict degradation rate constants. The study found that ZVI/Cu can effectively degrade not only aliphatic DBPs but also new emerging aromatic DBPs formed in chlorinated and chloraminated drinking water. A quantitative structure-activity relationship model was developed to predict the degradation rate constants of other aromatic DBPs, and optimized descriptors were identified.
