“…This is further supported by the fact that towards the end of 2013 there was an intense effort to clean-up the reservoir by the local administration to offer drinking water from this waterbody. Similarly, in a nearby waterbody, Lake Xochimilco (Mexico City) once had high levels of triclosan, an endocrine disruptor (DuranAlvarez et al, 2015) but after a few years, its concentrations were undetectable in the same waterbody (González-Pérez et al, 2018).…”

To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude eutrophic urban waterbody from Mexico, every month for a year. Qualitative analysis of zooplankton revealed 28 rotifer species and four cladoceran crustaceans plus one unidentified copepod. Cephalodella catellina (1400 ind L -1 ), Horaella thomassoni (550 ind L -1 ), Conochilus dossuarius (380 ind L -1 ) and Filinia longiseta (25 ind L -1 ) had higher peak density than other rotifers. Based on the concentrations of nitrates and phosphates, chlorophyll a levels or different diversity indices (e.g., Carlson, Shannon-Wiener, Pantle and Buck, Ejsmont-Karabin's TSI Rot ), the waterbody is eutrophic to hypertrophic, depending on the season. In this waterbody we observed high densities of Aphanothece sp. which is a toxic picocyanobacterium. During the blooms of Aphanothece, we also recorded higher densities of H. thomassoni and C. catellina. Based on the gut contents we found that both these rotifer species feed on Aphanothece in this waterbody. This study thus suggests the potential growth of Horaella, Cephalodella, Conochilus and Filinia in this eutrophic reservoir containing blooms of Aphanothece.

“…The bioavailability of pharmaceutical drugs in aquatic ecosystems has a signi cant ecological effect on the aquatic biota. For instance, in primary consumers such as rotifers and cladocerans, these compounds negatively affect their biological parameters (life span, reproductive rates, generation time, and population increase) (Varano et al, 2017;González-Pérez et al, 2018). On the other hand, pharmaceuticals can alter the behaviour traits of secondary consumers ( shes) and affects their ecological interaction (Brodin et al, 2014).…”

“…These organisms respond quickly to environmental stresses caused by heavy metals, pesticides, pharmaceuticals, among others; hence their relevance in ecotoxicological studies (Snell and Marcial, 2017). The most used endpoints to estimate ecological risk for rotifer populations are acute (LC 50 ) and chronic (instantaneous growth rate (r)) toxicity tests (Rico-Martínez et al, 2013;González-Pérez et al, 2018). The r is a good measure of response to toxicants since it integrates potentially complex interactions among life-history traits, including reproductive and mortality rates (Forbes and Calow, 1999), which is unattainable through acute tests.…”

Synergistic effect of chloroquine and copper to the euryhaline rotifer Proales similis

Chloroquine (CQ) has been widely used for many years against malaria and various viral diseases. Its important use and high potential to being persistent make it of particular concern for ecotoxicological studies. Here, we evaluated the toxicity of CQ alone and in combination with copper (Cu) to the euryhaline rotifer Proales similis. All experiments were carried out using chronic toxicity reproductive ve-day tests and an application factor (AF) of 0.05, 0.1, 0.3 and 0.5 by multiplying the 24-h LC 50 values of CQ (4250 µg/L) and Cu (68 µg/L). The rate of population increase (r, d -1 ) ranged from 0.50 to 52 (controls); 0.19 to 0.39 (CQ); 0.09 to 0.42 (Cu); and -0.03 to 0.29 (CQ-Cu) and decreased signi cantly as the concentration of both chemicals in the medium increased. Almost all tested mixtures induced synergistic effects, mainly as the AF increased. We found that the presence of Cu intensi es the vulnerability of organisms to CQ and vice versa. These results stress the potential hazard that these combined chemicals may have on the aquatic systems. This research suggests that P. similis is sensitive to CQ as other standardized zooplankton species and may serve as a potential test species in the risk assessment of emerging pollutants in marine environments.

“…TCS has become ubiquitous in the environment in large part due to discharge from various sources associated with consumer products and its ability to infiltrate water systems as a result of its heavy use by consumers. This has been exacerbated by the recent COVID-19 pandemic, which has increased the demand for phenolic compounds to make various cleaning and other consumer products, with a compounded annual growth rate (CAGR) of approximately 4% [15,20]. The toxicity of TCS has been studied in numerous animal models, with interest dedicated to its effect on soil and aquatic ecosystem health.…”

Environmental pollution remains one of the most challenging problems facing society worldwide. Much of the problem has been caused by human activities and increased usage of various useful chemical agents that inadvertently find their way into the environment. Triclosan (TCS) and related phenolic compounds and derivatives belong to one class of such chemical agents. In this work, we provide a mini review of these emerging pollutants and an outlook on the state-of-the-art in nanostructured adsorbents and photocatalysts, especially nanostructured materials, that are being developed to address the problems associated with these environmental pollutants worldwide. Of note, the unique properties, structures, and compositions of mesoporous nanomaterials for the removal and decontamination of phenolic compounds and derivatives are discussed. These materials have a great ability to scavenge, adsorb, and even photocatalyze the decomposition of these compounds to mitigate/prevent their possible harmful effects on the environment. By designing and synthesizing them using silica and titania, which are easier to produce, effective adsorbents and photocatalysts that can mitigate the problems caused by TCS and its related phenolic derivatives in the environment could be fabricated. These topics, along with the authors’ remarks, are also discussed in this review.
