“…Mendonça et al (2013) concluded that Vibrio fischeri and Daphnia magna tests are suitable to distinguish and evaluate the effectiveness of treatments used in WWTPs. The same conclusion was drawn by Alkimin et al (2020), demonstrating the advantages of using L. minor to assess the toxicity of effluents. Thus, ecotoxicological studies have proved to be great tools in assessing the effectiveness of the instruments used in WWTPs for the treatment of wastewater, as well as unmasking the effects (synergism, antagonism, potentiation, or summation) of complex mixtures that may occur (Gargosova and Urminska 2017;Mendonça et al 2011a).…”

“…Several studies describe wastewater as a complex mixture, which may contain several compounds (impossible to completely quantify) that can inhibit the growth of macrophytes, namely steroids, hormones, heavy metals, and pesticides (Fekete-Kertész et al 2015). Although L. minor can remove toxic compounds and nutrients from wastewaters, while being often used as a phytoremediator (Alkimin et al 2020), it has also been demonstrated to be one of the most sensitive organisms used in a battery of ecotoxicological assays involving wastewaters (Blinova 2000(Blinova , 2004. Indeed, the here-obtained results showed that L. minor was one of the most sensitive species, where acute toxicity was observed in all samples before the biological treatment with MBR (samples A and B), and in win20 also samples C and D showed acute toxicity.…”

Ecotoxicological tools have proved to be sensitive and appropriate for the evaluation of the effectiveness of treatments used in wastewater treatment plants (WWTP). The objective of this study was to assess the applicability of bioassays and biomarkers to evaluate the efficiency of different treatments throughout WWTP samples[A—raw influent, B—preliminary effluent, C—final effluent, and D—receiving stream], seasonally over 1 year, through a multispecies approach: i) bacterial cell viability [Escherichia coli, Rhodopirellulla rubra, Arthrobacter sp., and Pseudomonas putida]; ii) microalgae Raphidocelis subcapitata and the macrophyte Lemna minor growth inhibition; and iii) microcrustacean Daphnia magna acute and feeding rate assays. Total chlorophyll, malondialdehyde, and proline levels were evaluated in L. minor, and catalase, glutathione-S-transferase activities, and thiobarbituric acid reactive substances levels were quantified in D. magna, after exposure to wastewater samples. Overall, the tested species showed different sensitivities, P. putida = Arthrobacter sp. = R. rubra < R. subcapitata < E. coli = D. magna = L. minor, to the collected samples. The results obtained in D. magna and L. minor assays demonstrated that these organisms can be used in programs for monitoring and environmental assessment of wastewater effluents. The present study demonstrates the usefulness of ecotoxicological tools, with multispecies and different endpoints, to assess the effectiveness of WWTPs. Moreover, it is important to ensure that WWTP implements a monitoring program to minimize the discharge of effluents that compromise the environment in order to guarantee the good ecological quality of the environmental ecosystems.

“…The photosynthesis activity increases the dissolved oxygen in water, thus creating aerobic conditions in wastewater in favor of aerobic bacterial activity to reduce BOD and COD contents [34]. This can be an indication that wastewater would have a lesser impact on the environment after being treated using the phytoremediation method [35]. The results indicated that all plants used as phytoremediation agents in this study were able to reduce the TSS, NH 3 -N and COD contents in sewage wastewater samples with different rates of reduction.…”

The rapid growth of industries has resulted in wastewater generation containing different organic and chemical substances channeled into the water body. This causes the arising of water pollution issues in many regions. The phytoremediation method was introduced in the process of treating water pollution as it is low cost and environmentally friendly. Lemna minor, Salvinia minima, Ipomoea aquatica and Centella asiatica were chosen in this study because they have tolerance to various pollution conditions and are able to remove organic pollutants and heavy metals. The objectives of this study were to determine the water quality before and after treatment, to determine the rate of reduction in total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and chemical oxygen demand (COD) in sewage water through the phytoremediation method and to assess the effectiveness of the plants in the phytoremediation of sewage wastewater. It was found that, Lemna minor, Salvinia minima, Ipomoea aquatica and Centella asiatica were able to reduce TSS by 50.8%, 77.6%, 85.6% and 67.6%, respectively; NH3-N by 80.4%, 89.9, 97.3% and 79.1%, respectively; and COD by 75%, 82%, 44.8% and 36.46%, respectively. In this study, it was found that sewage wastewater treatment using Ipomoea aquatica was more efficient in reducing NH3-N and Salvinia minima was more efficient in reducing TSS and COD values.

“…The measured endpoints were average swimming time (ST), and average swimming distance (SD). This experimemntal analysis was based on the studies conducted by Alkimin et al (2020), and Dionísio et al (2020), who validated this analytical time frame, and the measurement of such behavioral traits. Changes in swimming behavior can be very subtle, difficult to observe with the naked eye, and digital analysis and video recording appear as sensitive tools capable of monitoring various parameters related to mobility (Dodson et al, 1995); in our case the evaluation of the locomotor behavior was performed by using an automated video recording system (Viewpoint Zebrabox®), equipped with internal LED (recording light) and infrared (dark recording) lighting, with a camera mounted for the detection of movements.…”
