“…The sorption rate of these pollutants on plastics debris can vary among polymers: shape, crystallinity, surface functional groups, and ageing of particles affect the sorption capacity of pollutants [98,99]. For example, polyethylene pellets have a higher affinity for PCB than those of polypropylene [95,100].…”

“…The interaction between POPs and MPs is also less well understood for sediments: only a few studies have attempted to combine the adsorption and desorption of POPs by MPs and sediments. For example, Wang and Wang [99] observed a higher adsorption rate of PAHs on different polymer pellets than in natural sediments. Nonetheless, the equilibria between the adsorbed and dissolved phase need to be further investigated to understand the final sink of POPs and consequent ecotoxicological effects [105,106].…”

“…The best results can be obtained only by combining both methods, especially for smaller fractions (<50 µm), since Raman spectroscopy results more time-consuming but more reliable for small particles. After the qualification of polymers in samples, it is possible to investigate the morphological structure of plastic particles by using EDS-SEM microscopy [27,99,159]. This technique can provide extremely clear and high-magnification images of plastic-like particles, permitting the observation of the surface texture of the particles in order to discriminate microplastics from organic particles.…”

Plastic is one of the most commonly produced and used materials in the world due to its outstanding features. However, the worldwide use of plastics and poor waste management have led to negative impacts on ecosystems. Plastic degradation in the environment leads to the generation of plastic particles with a size of <5 mm, which are defined as microplastics (MPs). These represent a global concern due to their wide dispersion in water environments and unclear potential ecotoxicological effects. Different studies have been performed with the aim of evaluating the presence and impacts of MPs in the marine environment. However, the presence of MPs in freshwater systems is still poorly investigated, making data retrieval a difficult task. The purpose of this review is to identify the main aspects concerning MPs pollution sources in lakes and rivers, with a focus on freshwater sediments as a site of accumulation and as the habitat of benthic organisms, which are key components of food webs and play a fundamental role in energy/contaminant transfer processes, but are still poorly considered. Through this review, the sources and fate of MPs in freshwater are analysed, ecotoxicological studies focused on sediments and benthic fauna are exposed, the most frequently used sampling and analysis strategies are reported, and future trends of MPs analysis in this field are proposed.

“…The sorption/desorption mechanism can be monitored or studied using some spectroscopic techniques (reviewed by Verla et al [172]) as well as using different sorption kinetics and isotherms models such as pseudo-first-order (PFO), pseudo-second-order (PSO), or the intra-particle models [69,176,177,186], linear, Freundlich, Langmuir models, Polanyi-Dubinin-Manes model [71,147], porevolume diffusion model (PVDM), pore-volume and surface diffusion model (PVSDM) ( [119,120,151]), poly-parameter linear free energy relationship [72,156] and film-pore mass transfer (FPMT) [56].…”

Current problem facing researchers globally is microplastics as well as toxic chemical pollution of the ecosystem. Microplastics carry toxic chemicals in the ecosystem serving as a vector for transport. In this study, a review of the literature has been conducted with the following objectives: (1) to summarize the concentrations of toxic chemicals such heavy metals and hydrophobic organic contaminants sorped on microplastics; (2) to evaluate their spatial distribution regarding adsorbed contaminant; (3) to discuss plausible mechanism by which microplastics adsorp or desorp toxic chemicals in the environment; (4) to discuss implications of their occurrence in air, water and soil media; and (5) to discuss the impact of ingested microplastics to human health. Microplastics are ubiquitous environmental contaminant. Concentrations of sorped toxic chemical varied by location which represents a local problem; industrialized areas (especially areas experiencing crude oil-related activities or have history of crude oil pollution) have higher concentrations than less industrialized areas. Ingestion of microplastics has been demonstrated in a range of marine and soil organisms as well as edible plants, thus possibly contaminating the base of the food web. Potential health effect to human is by particle localization, chemical toxicity and microbial toxins. We conclude by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.
