“…Within the plastic concept, the smaller particles (< 5 mm) known as microplastics (MPs) have gained more attention due to their potential to adsorb hazardous chemicals available in aquatic systems, such as metals and POPs, although their toxicity along the food web does not yet has been proved (Eriksen et al, 2018;Yu et al, 2019;Enfrin et al, 2020;Yang et al, 2020). MPs is acknowledged as ubiquitous in the marine environment as their diminutive size make them easily welcoming in biogeochemical and ecological processes (Remy et al, 2015;Zhao et al, 2016;Ferreira et al, 2019).…”

Despite their representativeness, most studies to date have underestimated the amount of microfibers (MFs) in the marine environment. Therefore, further research is still necessary to identify key processes governing MF distribution. Here, the interaction among surface water temperature, salinity, currents and winds explained the patterns of MF accumulation. The estimated density of floating MFs is ~5900 ± 6800 items m − 3 in the global ocean; and three patterns of accumulation were predicted by the proposed model: (i) intermediate densities in ocean gyres, Seas of Japan and of Okhotsk, Mediterranean and around the Antarctic Ocean; (ii) high densities in the Arctic Ocean; and (iii) point zones of highest densities inside the Arctic Seas. Coastal areas and upwelling systems have low accumulation potential. At the same time, zones of divergences between westerlies and trade winds, located above the tropical oceanic gyres, are predicted to accumulate MFs. In addition, it is likely that the warm branch of the thermohaline circulation has an important role in the transport of MFs towards the Arctic Ocean, emphasizing that surface water masses are important predictors. This study highlights that the Arctic Ocean is a dead end for floating MFs.

“…Another review discussed how environmental factors affect the properties of microplastics and sorption of contaminants by micro/nanoplastics (Yu, Yang, Zhu, Bai, & Ma, 2019). The factors that influenced the sorption behavior of virgin state microplastics included hydrophobicity, particle size, pH, salinity, and of used state microplastics included pH, salinity hydrogen boding, hydrophobicity, specific surface ration.…”

A review of the literature published in 2019 on topics associated with the fate of environmental pollutants is presented. Environmental pollutants covered include pharmaceuticals, antibiotic-resistant bacteria and genes, pesticides and veterinary medicines, personal care products and emerging pollutants, PFAS, microplastics, nanomaterials, heavy metals and radionuclides, nutrients, pathogens and indicator organisms, and oil and hydrocarbons. For each pollutant, the occurrence in the environment and/ or their fate in engineered as well as natural systems in matrices including water, soil, wastewater, stormwater, runoff, and/or manure is presented based on the published literature. The review includes current developments in understanding pollutants in natural and engineered systems, and relevant physico-chemical processes, as well as biological processes.

“…However, it is reported that the concentration of organic pollutants, such as persistent organic pollutants (POPs), on MPs was significantly higher (up to~1 million times) than that in the surrounding environment (Rios et al 2010;Teuten et al 2007). The large surface-tovolume ratio, which depends on the morphology of MP particles, and the hydrophobic nature of MPs promote the adsorption of POPs on the surface of MPs (Kwon et al 2017;Yu et al 2019). Fred-Ahmadu et al (2020) reported that PE could adsorb more organic contaminants than other plastics, namely PP and PVC.…”

Microplastics (MPs) are unregulated and emerging contaminants, which are continuously released due to human activities in the environment through several pathways. The presence of MPs poses threats to the environment, organisms, and human health. The discharge of treated effluent from wastewater treatment plants (WWTPs) is a major source of MP input, especially in the form of microfibers, into the aquatic environment, whereas the application of sludge and compost is a crucial pathway transferring MPs to terrestrial environment. Meanwhile, MPs are produced from industrial processes and the use of plastic consumer goods and personal care products. MPs become more hazardous when they adsorb persistent organic pollutants and heavy metals or attach with pathogenic microorganisms from wastewater and sludge. However, there is little comprehensive information available about the collaborative role of wastewater and sludge in MP contamination. Studies about remediation strategies and their removal mechanisms of MPs in WWTPs are limited. Therefore, it is important to develop cost-effective detection methods of MPs for routine monitoring in wastewater and sludge samples and understanding of fate and inhibitory effects of MPs in wastewater and sludge treatment processes, before developing the mitigation measures of MP contamination. This chapter summarizes the sources and pathways of MPs, discusses the impacts of MPs on environment and human health, and reviews the current practices on detection, quantification, and qualification of MPs. In addition, this chapter provides insights into the source control of MPs through polices and education.
