“…POPs are a group of toxic chemicals that are resistant to degradation and therefore can persist in the environment for extended periods of time (D’Agostino et al 2020 ). For example, Cui et al ( 2023 ) observed that the formation of biofilm onto HDPE MPs increases the adsorption of various POPs, including polybrominated diphenyl ethers, polychlorinated biphenyls, and α-hexabromocyclododecane. They also reported that biofilm formation increases the surface area of HDPE MPs, potentially contributing to the increased chemical adsorption.…”

Microplastics (MPs) are of global concern due to their slow degradation in the environment and the potential of inducing adverse effects on organisms. In aquatic ecosystems, microbes routinely colonize MPs and develop biofilms on their surfaces. Biofilms are assemblages of surface-associated microbial cells that are enclosed in an extracellular polymeric substance. Emerging evidence has suggested that the development of biofilm can alter the physicochemical properties and the pollutant adsorption capability on MPs. In this article, we review the impacts of biofilm formation on MP properties, ecotoxicity, and fate. First, we summarize the environmental factors that modulate biofilm formation, as well as the unique components of biofilm on MP. Next, we review current understanding on the influence of biofilm formation on the physical and chemical properties of MPs and discuss how these changes affect their pollutant adsorption capacity. Finally, we discuss how biofilm formation on MPs affects their ingestion by organisms and nutrient cycling in aquatic environments. Graphical Abstract

“…Although particle size does not affect sorption capacity of contaminants as much as other parameters, such as polymer type and surface area, it still plays a role in the sorption kinetics between microplastic and contaminant [ 88 ]. Cui et al [ 101 ] investigated the sorption of organic contaminants onto different microplastics and found that although the size did not significantly affect sorption capacity, it did affect equilibrium time. It is clear that there are polymer-specific factors that can either increase or decrease the sorption capacity of contaminants onto microplastics, and it is never just one factor that has influence over the reaction.…”

Over the years, it has become evident that microplastics are one of the most important contaminants of concern requiring significant attention. The large abundance of microplastics that are currently in the environment poses potential toxicity risks to all organisms that are exposed to them. Microplastics have been found to affect the physiological and biological processes in marine and terrestrial organisms. As well as being a contaminant of concern in itself, microplastics also have the ability to act as vectors for other contaminants. The potential for microplastics to carry pollutants and transfer them to other organisms has been documented in the literature. Microplastics have also been linked to hosting antibiotic resistant bacteria and antibiotic resistance genes which poses a significant risk to the current health system. There has been a significant increase in research published surrounding the topic of microplastics over the last 5 years. As such, it is difficult to determine and find up to date and relevant information. This overview paper aims to provide a snapshot of the current and emerging sources of microplastics, how microplastics can act as a contaminant and have toxic effects on a range of organisms and also be a vector for a large variety of other contaminants of concern. The aim of this paper is to act as a tool for future research to reference relevant and recent literature in this field.

“…Finally, besides their capacity to adsorb and desorb different substances, MPs, whether in water or soil, tend to be colonised by a microbial community referred to as the "plastisphere". 19 The microbial community facilitate the retention of different toxic chemical compounds, such as insecticides, polychloride biphenyls and antibiotics, among others [20][21][22][23] Besides causing damage and alterations to the GIT of aquatic and terrestrial animals that consume MPs accidently, 17,24,25 MPs can act as vectors along the food chain for other contaminants with bio-magnication phenomena, nally having a negative impact on animals and human beings. [26][27][28] The identication of nine types of plastics in human faeces, 29 PET, PE and PS (700 nm) in blood in twenty-two volunteers, 5 PE, PVC and PP in human breastmilk, 30 and PP and PS in six human placentas of healthy mothers 31 dramatically conrms that even before birth humans are being exposed to MPs.…”
