“…On the other hand, several studies have suggested that when organisms are exposed to microplastics in combination with pollutants, the overall ecotoxicity may be reduced (Wakkaf et al, 2020; Zhang et al, 2020). This is because some microplastics can act as a sink for pollutants, lowering bioavailability (Liu et al, 2019).…”

The scientific understanding regarding sources, occurrence, and effects of microplastics in the aquatic environment has advanced rapidly, leaving some meaningful knowledge gaps virtually untouched. One of them is the interactions of microplastics and biofilms, microbial communities ubiquitous in aquatic ecosystems and fundamental for a range of ecosystem level processes. It is evident that biofilms can quickly develop on microplastics' surface and consequently change particle properties and as such its fate and ecotoxicity. Moreover, microplastics interact with ubiquitous biofilms that are developed on any surfaces in aquatic ecosystems.

“…Each microcosm operated as a closed system, with continuous ventilation provided by an aquarium pump. The reliability of the current experimental devices was tested previously by several authors ( Austen et al, 1994 ; Mahmoudi et al, 2005 ; Essid et al, 2020 ; Wakkaf et al, 2020 ; Hedfi et al, 2021 ).…”

“…Spherical particles of microplastics (>40 µm; MW = 48,000 g.mol −1 , 16 mmol of Cl. g −1 , 99%) were added as such as to contaminate 100 g of defaunated sediment with a concentration of 20 mg.kg −1 [36].…”

“…The control experimental set "C" was obtained by mixing 100 g uncontaminated defaunated sediment with 200 g of natural sediment. Each system consisted of a 2-litre glass bottle, which was constantly aerated through an aquarium pump throughout the experiment [34,36].…”

A microcosm experiment was carried out to provide a deeper insight into the toxic mechanisms exerted by two lipid regulator agents, as well as their interactions with the polyvinyl chloride microplastic on marine meiofauna. Two concentrations of Atorvastatin “A” and of Simvastatin “S”, (i.e., 0.6 mg.kg−1 and 6 mg.kg−1), as well as a single dosage of polyvinyl chloride microplastics “P” at 20 mg.kg−1, separately and their combined mixtures (“AP” and “SP”) were used on coastline dwelling marine meiofauna, with a main focus on nematodes. The results showed a significant reduction in meiofauna abundance in treatments compared to control. SIMPER analysis highlighted a significant decrease in the abundance of epigrowth feeders (2A), which possess conical (co) tails, and indistinct (id) amphideal foveas compared to control microcosms, reflected mainly in the decrease in abundance of the species Prochromadorella longicaudata. Furthermore, the contamination with microplastic affected only the omnivores-carnivores guild. Another finding of the current experiment is that the mixtures of microplastic with drugs lead to synergic interactions that increased their toxic effects on marine nematode communities.
