“…Interestingly, it was found that the aquatic organisms used for the investigation of PS MNP toxicity were more likely to be invertebrates than fishes (32 vs. 24 studies). This is probably due to the high sensitivity, inexpensive management, and ease of running experimental tests with invertebrates compared to vertebrates, besides the ethical rationale for animal welfare [47]. Moreover, transcriptomics and metabolomics appeared to be the approaches used mostly for fishes (a total of 11 out of 24 studies used transcriptomics and a total of 11 out of 24 studies used metabolomics in fish), while in the case of aquatic invertebrates, the most common -omic approach used was found to be the transcriptomics (a total of 18 out of 32 studies).…”

In recent years, micro- and nanoplastics (MNPs) have represented an emerging threat for the aquatic environment due to their persistence and widespread distribution. Indeed, their small size and increased surface area lead to a high biological reactivity, which can be crucial for the health status of biota. To date, several studies have investigated lethal and sublethal endpoints of MNPs, while one of the main challenges is to understand their mechanisms of toxicity in a comprehensive manner. With this aim, the field of aquatic ecotoxicology can now benefit from the -omics approaches. This review focuses on the recent advances related to the use of transcriptomics, proteomics, and metabolomics to deeply investigate the molecular and biochemical responses of aquatic organisms, both fishes and aquatic invertebrates, to pristine polystyrene (PS) MNPs. The literature reviewed revealed that transcriptomics and metabolomics are the most frequently used -omic approaches. Overall, the studies taken into consideration shed light on the events triggered by PS MNPs at molecular and cellular levels, identifying as mechanisms of toxicity the pathways involved in oxidative stress, energy metabolism, immune response, and the nervous system. Future studies should therefore focus on the use and integration of multi-omics approaches for a more comprehensive understanding of the mechanisms involved in MNPs toxicity.

“…Os ensaios ecotoxicológicos são importantes parâmetros para avaliação da toxicidade de efluentes bruto e pós-tratado. Esses bioensaios fazem uma avalição do impacto de efluentes em espécies vivas e avaliam o desempenho dos processos de tratamento de águas residuárias visto que, as análises químicas não detectam as interações sinérgicas, antagônicas ou aditivas entre os contaminantes (Aydin et al, 2015;Methneni et al, 2021).…”

The most diverse forms of pollution and contamination, especially from the industrial sector, reinforce the need to optimize industrial processes in the search for reducing waste generated or even creating and improving appropriate techniques for removing organic compounds in solid waste and effluents. Wastewater resulting from chemical processes, in general, has a complex composition and causes environmental problems when not treated appropriately. An efficient proposal for the treatment of effluents of high chemical complexity and high concentration of suspended solids is Fenton Coagulation. This process reconciles the coagulation process with iron ions and reuses the residual iron concentration to apply a subsequent treatment, the Fenton process. Therefore, the objective of this work is to address the hybrid Fenton coagulation process and discuss important aspects of its use for the treatment of effluents.

“…Wastewater is generated through various sources such as homes, industries, farms, and various other ways. As a result, the complexity of wastewaters comprising of both natural and synthetic organic substances and high volumes of industrial chemicals are possible contaminants that cause toxic effects in wastewater [3]. These constitute potential dangers to the natural water system and hence becomes hazardous to life and the environment [30].…”

Management of wastewater from diverse sources are important because effluents are discharged into the aquatic environment after treatment. In this study, the water quality of the Veldwachters River and associated ecotoxicity risks of the wastewater treatment plant’s (WWTP) effluent were evaluated. Physicochemical characterisation over four seasons and ecological risk assessment of WWTP’s effluent using aquatic organisms comprising of the producer Raphidocelis subcapitata, consumer Daphnia magna and decomposer Tetrahymena thermophila as experimental models were investigated. The crustaceans were subjected to 48 h exposure for mortality while both algae and the protozoan were exposed for growth inhibitions at 72 h and 24 h respectively. Physicochemical characteristics were within regulatory limits. Growth inhibition was observed in autumn and winter for R. subcapitata and in summer and spring for T. thermophila. Crustaceans D. magna (consumer) was classified as Class III (acute toxicity) for the effluent in all seasons. Meanwhile, the most sensitive organism in the applied battery of biotests was the protozoan T. thermophila (decomposer), demonstrating a toxic unit (TU) > 100, while R. subcapitata and D. magna demonstrated 1 TU < 10. These results showed that the effluent have potential toxicological effects on aquatic organisms and provided insights into the required intervention strategies for pollution reduction.
