“…In these environments, plastic pollution especially in the form of microplastics (MPs), which were first reported in the late 1960s, pose a serious threat with ecological, social, and economic impacts, and is a global threat that could affect human health and biological diversity in the near- to medium-term future (Ryan 2015 ; Blettler et al 2018 ). Several studies have reported interactions between MPs and a wide range of organisms in both marine and terrestrial environments, showing effects ranging from ingestion and other gastrointestinal problems, reduced fitness, systemic immunological responses, occurrence of severe toxicological effects, reduced fecundity and increased mortality, among many others (Cole et al 2013 ; Li et al 2020 ; Yuan et al 2023 ).…”

Plastic pollution in the form of microplastics (MPs), poses a significant threat to natural ecosystems, with detrimental ecological, social, and economic impacts. This review paper aims to provide an overview of the existing research on the interaction between microbial biofilms and MPs in natural environments. The review begins by outlining the sources and types of MPs, emphasizing their widespread presence in marine, freshwater, and terrestrial ecosystems. It then discusses the formation and characteristics of microbial biofilms on MPs surfaces, highlighting their role in altering the physicochemical properties of MPs and facilitating processes such as vertical transport, biodegradation, dispersion of microorganisms, and gene transfer. Different methods used to assess these interactions are discussed, including microbiological and physicochemical characterization. Current gaps and challenges in understanding the complex relationships between biofilms and MPs are identified, highlighting the need for further research to elucidate the mechanisms underlying these complex interactions and to develop effective mitigation strategies. Innovative solutions, including bioremediation techniques and their combination with other strategies, such as nanotechnology, advanced filtration technologies, and public awareness campaigns, are proposed as promising approaches to address the issue of MPs pollution. Overall, this review underscores the urgent need for a multidisciplinary approach to combating MPs pollution, combining scientific research, technological innovation, and public engagement to safeguard the health and integrity of natural ecosystems.

“…The antioxidant and detoxification response induced by MP exposure has been widely evidenced in many fish species as for example Cyprinodon variegatus [13], Sparus aurata [14], or Seriola dumerili [15]. Many studies investigating the potential effects of MP intake have been conducted with teleost fish species and have been analysed in some meta-analyses [16,17]. However, there are fewer and more recent publications on the effects of this type of contaminant on cartilaginous fish [18][19][20][21][22][23].…”

In recent years, there has been an increase in the reporting of plastic pollution in the marine environment and its effects on marine animals, especially bony fish. However, the prevalence and effect, particularly concerning biomarkers of oxidative stress, in elasmobranchs remain underreported and unknown. In this study, microplastics were observed in two elasmobranch species from the Balearic Islands: the small-spotted catshark (Scyliorhinus canicula) with an average of 4.38 ± 1.77 items per individual, and the blackmouth catshark (Galeus melastomus) with an average of 8.31 ± 2.46 items per individual. Moreover, for the first time, antioxidant and pro-inflammatory responses were determined in the digestive tract of individuals of both species. Specifically, the activation of antioxidant defences, mainly superoxide dismutase activity and glutathione levels, was observed, while the pro-inflammatory marker myeloperoxidase activity was also greater in individuals with a high abundance of microplastic items. Additionally, a significant increase in glutathione S-transferase activity in catsharks with high microplastic ingestion was evidenced, suggesting that the detoxification process was activated. Overall, the results of this study highlight that both catshark species are ingesting microplastics, which, in turn, are causing physiological effects at a cellular level. Considering this, continued monitoring of these species should include the presence of microplastics, and the results from this study can serve as baseline data for future research.
