“…In the tropical species Ceriodaphnia cornuta, the LC 50 reported by Pérez-Legaspi et al (2017) for Cr(VI) was 1.16 mg L −1 , which indicates a lesser sensitivity to this metal than that of C. dubia, contrary to what these authors suggest that C. cornuta is a more sensitive cladoceran. In other tropical cladocerans, like Pseudosida Frontiers in Environmental Science frontiersin.org ramosa, the LC 50 was 29 µg L −1 (20-60 µg L −1 ), indicating a higher sensitivity.…”

Cladocerans are frequently used as test organisms in aquatic toxicology studies. For practical reasons (bioethical and economic), efforts are currently made in search of alternative animal models and in defining short-lasting test methods that will allow reliable evaluation of the chronic effect of chemical contaminants. The use of small-sized invertebrates, like the Ceriodaphnia dubia cladoceran, represents a good option and has been included in diverse testing protocols; however, the use of reduced volumes and shortened exposure times, as well as higher temperatures to accelerate their development could influence the results and lead to imprecise conclusions. The present study aimed to evaluate the effects of different test volumes, temperature, and exposure time on the toxicity of hexavalent chrome in C. dubia. In acute and chronic assays, three test volumes (5, 15, and 25 mL) were used. Once the LC50 was determined, four sublethal concentrations (0.01, 0.02, 0.04, and 0.08 mg L−1) of Cr(VI) were applied daily to each of the three test volumes for 21 days, evaluating the progeny and survival of adults. The LC50 values did not differ at 20°C, but at 25°C they were significantly lower in 5 mL. The chronic toxic effects varied depending on the test volume and exposure time. Significant effects were observed on day 7 of exposure (corresponding to the third reproduction) in the accumulated progeny only in the volume of 5 mL. Based on the aforementioned, it is necessary to revise whether the short-term and small-scale methods are not underestimating the detection of chronic effects.

Toxicity and Hazards of Biodegradable and Non-Biodegradable Sunscreens to Aquatic Life of Quintana Roo, Mexico

Sunscreens have spread widely into aquatic systems over the last 18 years in Quintana Roo, Mexico. This contamination is caused by intensive use as a result of leisure activities, as sunbathers apply the substances intensively (up to 83.75% of tourists and locals). Moreover, 25% of the compounds are mainly released into the water through topical products washing off. On average, 300,000 tourists arrive every week in Quintana Roo, increasing the contamination. In addition, there are no recent studies on sunscreen toxicity and the hazards this represents for the native zooplankton of Quintana Roo. In order to assess their adverse effects, acute toxicity was assessed for nine sunscreens (five non-biodegradable and four biodegradable) in four zooplankton species (Brachionus cf ibericus, Cypridopsis vidua, Diaphanocypris meridana, and Macrothrix triserialis). In total, 21 LC50 values were obtained, which are the baseline values for estimating risk and for determining the expected maximum permissible concentration. Our data on toxicity to freshwater species compared to marine species indicate that freshwater species are more sensitive than marine species. In conclusion, biodegradable sunscreen posed a moderate risk, and non-biodegradable posed a high risk. Our outcomes suggested that the maximum permissible concentrations for the contamination of sunscreens were 8.00E-05 g/L for non-biodegradable and 1.60E-04 g/L for biodegradable sunscreens.

“…Los cladóceros son considerados representantes del zooplancton dulceacuícola, pues ocupan un lugar clave en la red trófica, con altas tasas de reproducción y fácil cultivo (Ismiño, et al, 2020;Pérez-Legaspi et al, 2017). El grupo cuenta con al menos 110 especies registradas hasta ahora en el país (Elías-Gutiérrez et al, 1999;Elías-Gutiérrez et al, 2008).…”

Los cladóceros son crustáceos utilizados como alimento vivo para larvas de peces debido a su aporte nutricional y fácil cultivo. El objetivo fue identificar las especies de cladóceros presentes en ambientes acuáticos temporales y permanentes del estado de Morelos. Se tomaron algunos parámetros físicos y químicos, además de las recolectas del zooplancton, en un total de 130 cuerpos de agua. Se determinaron un total de 33 especies comprendidas en las familias Bosminidae, Chydoridae, Daphniade, Ilyocryptidae, Macrothricidae, Polyphemidae, Sididae y Moinidae, donde sobresalen por su abundancia y frecuencia las especies de la familia Daphnidae. Se reporta que en estos sistemas acuáticos se presentan las especies que son utilizadas como alimento vivo, como es el caso de Moina cf. micrura, Diaphanosoma birgei, Daphnia laevis y Daphnia cf. mendotae. Se registró a Moina wierzejski como especie que habita tanto en lagos, presas y embalses, la cual es utilizada como alimento para larvas de peces.
