“…The diatomite particles were sieved in the same way to obtain the size fraction ≤63 µm. In our previous work, we confirmed that the cups were made of PS and had low but detectable concentrations of chemicals which could not be matched to substances commonly used in plastics (see Weber et al [2020] for details). Further, scanning electron microscopic images of PS fragments as well as diatomite particles are published in Weber et al (2021).…”

“…The microplastic and the diatomite powder contained 287 526 and 4 632 990 p mg –1 , respectively. Particle size distribution of the PS and the diatomite suspensions increased exponentially with decreasing particle size; 90% of the microplastic and the diatomite particles were smaller than 12.4 and 11.8 µm, respectively (for detailed methods and results see Weber et al [2020]).…”

“…The remaining antioxidant capacity in the midgut gland was measured with the oxygen radical absorbance capacity (ORAC) assay (Ou et al 2001; Furuhagen et al 2014). Further methodological details are provided in Weber et al (2020). Because of highly divergent results for midgut gland with a wet weight <5 mg compared to midgut gland >5 mg, we excluded results on energy reserves and oxidative stress from individuals with an midgut gland <5 mg ( n = 7–10).…”

The ubiquity of microplastics in aquatic ecosystems has raised concerns over their interaction with biota. However, microplastics research on freshwater species, especially mollusks, is still scarce. We, therefore, investigated the factors affecting microplastics ingestion in the freshwater mussel Dreissena polymorpha. Using polystyrene spheres (5, 10, 45, 90 µm), we determined the body burden of microplastics in the mussels in relation to 1) exposure and depuration time, 2) body size, 3) food abundance, and 4) microplastic concentrations. D. polymorpha rapidly ingested microplastics and excreted most particles within 12 h. A few microplastics were retained for up to 1 wk. Smaller individuals had a higher relative body burden of microplastics than larger individuals. The uptake of microplastics was concentration-dependent, whereas an additional food supply (algae) reduced it. We also compared the ingestion of microplastics by D. polymorpha with 2 other freshwater species (Anodonta anatina, Sinanodonta woodiana), highlighting that absolute and relative uptake depends on the species and the size of the mussels. In addition, we determined toxicity of polystyrene fragments (≤63 µm, 6.4-100 000 p mL -1 ) and diatomite (natural particle, 100 000 p mL -1 ) in D. polymorpha after 1, 3, 7, and 42 d of exposure, investigating clearance rate, energy reserves, and oxidative stress. Despite ingesting large quantities, exposure to polystyrene fragments only affected the clearance rate of D. polymorpha. Further, results of the microplastic and diatomite exposure did not differ significantly. Therefore, D. polymorpha is unaffected by or can compensate for polystyrene fragment toxicity even at concentrations above current environmental levels.

“…Esto se puede relacionar con un proceso de aclimatación que desarrollaron los organismos frente a la variación de temperatura (Widdows, 1978). Para los días 14 y 21, los individuos tuvieron una reducción de la TF a 23 y 26 °C, lo cual pudo generar la reducción de la frecuencia de la apertura valvar, conducta natural de sobrevivencia de los mitílidos frente a condiciones adversas como el incremento de la temperatura (Weber et al, 2020). Kratina et al (2019), consideran que la interacción de MPs y temperatura se presenta de manera antagonista; sin embargo, nuestro estudio demostró que ambos factores (0.125 mg/l y 0.250 mg/l) (17, 20, 23 y 26 °C), dentro de los rangos límites para S. algosus, ocasionaron la reducción de la TF.…”

Introducción: La presencia de microplásticos (MPs, partículas menores a 5 mm) y el incremento de la temperatura en los océanos, vienen generando perturbaciones en la vida marina, que se pueden relacionar con alteraciones en el metabolismo de organismos filtradores, como los mitílidos. Objetivo: Se evalúa el efecto de diferentes temperaturas y concentraciones de MPs sobre la tasa de filtración (TF) de Semimytilus algosus. Métodos: Una muestra de organismos (N = 72) fue expuesta a cuatro temperaturas (17, 20, 23 y 26 °C), y un testigo sin microplásticos (MPs0) y dos concentraciones de MPs (< 125 µm) de 0.125 mg/l (MPs1) y 0.250 mg/l (MPs2), todos en combinación con la microalga Isochrysis galbana (1x106 cel/ml/día) por 21 días. Resultados: A medida que aumentó la concentración de MPs, se redujo la TF de S. algosus. Respecto a la temperatura, durante el día 7 se observó una mayor TF a 23 °C en todos los tratamientos, y para los días 14 y 21 se obtuvieron los menores valores de TF a 23 y 26 °C. La acción conjunta del incremento de temperatura y MPs, afectó negativamente la TF de S. algosus, donde ambos factores ocasionaron el descenso de la TF para todos los tiempos de evaluación. No se registró mortalidad a 17 °C para ningún tratamiento, y en el caso de mitílidos expuestos a MPs1 y temperaturas de 20 y 26 °C se presentó la mayor mortalidad (67 %). Conclusiones: El estudio demuestra el efecto adverso del incremento de temperatura y MPs sobre la TF de S. algosus.

“…Polystyrene microplastics exposed to the freshwater mussel Dreissena polymorpha altered the behavior and oxidative stress response based on the size of particles indicating the stressor effect of the pollutant in the aquatic ecosystems (Weber et al, 2020). Incorporation of polyvinyl chloride and polyethylene terephthalate to caddisfly, Lepidostoma basale under laboratory condition reduced stability and are more prone to predation thereby limited the survival causing instability of food web in the aquatic ecosystems (Ehlers et al, 2020).…”

Microplastics Contamination in the Environment: An Ecotoxicological Concern

The accumulation of plastic products in the terrestrial and aquatic environment is one of the major concerns in recent years. The quality of the ecosystem is affected globally due to the large production, ubiquitous usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics, microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government legislations have been put forth to ban some products that are considered as the major contributor to plastic debris. Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage our environment
