“…Species of e.g. fungi, bacteria and algae has been shown to break down microplastics in laboratory studies (Bacha et al, 2023) and, freeze and thaw processes (Koutnik et al, 2022b), as well as water abrasion (Ravishankar et al, 2018) cause tension in the plastics and may contribute to enhanced fragmentation and downward mobility. For instance, Ren et al (2021) conclude in a review on microplastics in the soil-groundwater environment that transport of aged microplastics into the groundwater can occur due to enhanced mobility.…”

“…1 a) as they act as a vector for the transport of absorbed heavy metals, bacterial fish pathogens, multidrug resistant E. coli , persistent organic pollutants etc. (Enders et al 2015 ; Viršek et al 2017 ; Caruso, 2019 ; Song et al 2020 ), and the possible leaching of chemical components added during their manufacturing process (Groh et al 2019 ; Bacha et al 2023 ). In addition, microplastics provide a novel habitat for the growth of microbial biofilms containing algae, bacteria and fungi and can potentially spread microbial pathogens and antimicrobial resistance (Zettler et al 2013 ; Wu et al 2019 ; Guo et al 2020 ; Yuan et al 2020 ).…”

Microplastics pollution is major threat to ecosystems and is impacting abiotic and biotic components. Microplastics are diverse and highly complex contaminants that transport other contaminants and microbes. Current methods to remove microplastics include biodegradation, incineration, landfilling, and recycling. Here we review microplastics with focus on sources, toxicity, and biodegradation. We discuss the role of algae, fungi, bacteria in the biodegradation, and we present biotechnological methods to enhance degradation, e.g., gene editing tools and bioinformatics.

“…Further, plastics’ long residence times due to resistance to rapid degradation only enhance the potential risk to biota. Such risk extends to food webs, where plastics, as they are gradually broken down into smaller pieces and particles due to aging by UV light, mechanical stresses and microbes [ 6 ], may be transferred among trophic levels and reach as far as humans [ 7 ]. Investigations have shown that even sea salt used in kitchens is contaminated with plastic particles, thus representing a more direct pathway to ingestion by humans [ 8 ].…”

As a proxy for pollutants that may be simultaneously present in urban wastewater streams, the effects of two microplastics—polystyrene (PS; 10, 80 and 230 μm diameter) and polymethylmethacrylate (PMMA; 10 and 50 μm diameter)—on fertilisation and embryogenesis in the sea urchin Arbacia lixula with co-exposure to the pyrethroid insecticide cypermethrin were investigated. Synergistic or additive effects were not seen for plastic microparticles (50 mg L−1) in combination with cypermethrin (10 and 1000 μg L−1) based on evaluation of skeletal abnormalities or arrested development and death of significant numbers of larvae during the embryotoxicity assay. This behaviour was also apparent for male gametes pretreated with PS and PMMA microplastics and cypermethrin, where a reduction in sperm fertilisation ability was not evidenced. However, a modest reduction in the quality of the offspring was noted, suggesting that there may be some transmissible damage to the zygotes. PMMA microparticles were more readily taken up than PS microparticles, which could suggest surface chemical identity as potentially modulating the affinity of larvae for specific plastics. In contrast, significantly reduced toxicity was noted for the combination of PMMA microparticles and cypermethrin (100 μg L−1), and may be related to less ready desorption of the pyrethroid than PS, as well as cypermethrin activating mechanisms that result in reduced feeding and hence decreased ingestion of microparticles.
