“…The results of the long-term field study developed by Rochman et al (2014) suggest that PET, HDPE, PVC, LDPE, and PP tend to accumulate similar concentrations of metals. In a similar study, Gao et al (2019) found that PP had a higher adsorption capacity than PVC. Both studies suggest that the presence of biofilms may have influenced their results either by prompting the adsorbance of heavy metals or neutralizing the differences for metal accumulation between the types of plastics (Gao et al, 2019;Rochman et al, 2014).…”

“…It is unclear how much influence the polymer type of microplastics has in its capacity to adsorb heavy metals. Even though some laboratory experiments have found differences in the accumulation of heavy metals between plastic types (Fischer et al, 2007;Holmes et al, 2012) their representativeness is limited for the environmental microplastics as microplastics and the surrounding environment are in a dynamic exchange of metals ions (Gao et al, 2019;Rochman et al, 2014). Hence, field studies may be more accurate to describe this issue.…”

“…No studies were found that evaluated or discussed the issue of metals and organic pollutants associated with degradable microplastics from the environment. Therefore, although the ability of degradable and non-degradable plastics to sorb heavy metals and organic contaminants has been demonstrated in laboratory and field experiments (Ateia et al, 2020;Gao et al, 2019;Holmes et al, 2014;Liao and Yang, 2020; Rochman et al, 2014;Zhao et al, 2020), the interaction between the different chemical compounds that make up PAHs and microplastics is not well understood and therefore should be investigated further. On the other hand, we still know little about the actual fate in the environment or sorbed contaminants and the magnitude of this problem.…”

“…The affinity of the metal for a certain type of polymer lies in the charge of the polymer, porosity, and in the possible interactions between MPs and metal. Gao et al (2019) reported a higher lead sorption in PVC MPs compared to other polymers such as PP, PA, and PE. The same result was obtained in the Sr 2+ sorption studies when using PET, PVC, and PE (Guo and Wang 2019d).…”

Polymeric materials have had an exponential growth since the Second World War, so that in 2018 the annual world production was 359 million tons. This has generated a contamination problem because of its prolonged exposure to various chemical and environmental factors which have caused the formation of particles with a size less than 5 mm with a vast surface area and chemically stable and adjustable surface. For these reasons, these particles called microplastics (MPs) have been used as vectors for chemicals in the environment and, recently, in the removal of several pollutants from water. In this chapter, some representative examples of the use of microplastics for sorption of contaminants from water (pharmaceuticals, metal ions, and other organic compounds) are shown. The chapter is organized into two parts: the first part addresses MPs of commercial origin (virgin) and those reused after being

“…Though polymers were considered to be inert towards metals in the past [97], great attention has recently been paid to better understanding the interaction between heavy metals and microplastics [98][99][100][101][102][103][104][105][106][107][108].…”

The distribution and abundance of microplastics into the world are so extensive that many scientists use them as key indicators of the recent and contemporary period defining a new historical epoch: The Plasticene. However, the implications of microplastics are not yet thoroughly understood. There is considerable complexity involved to understand their impact due to different physical–chemical properties that make microplastics multifaceted stressors. If, on the one hand, microplastics carry toxic chemicals in the ecosystems, thus serving as vectors of transport, they are themselves, on the other hand, a cocktail of hazardous chemicals that are added voluntarily during their production as additives to increase polymer properties and prolong their life. To date, there is a considerable lack of knowledge on the major additives of concern that are used in the plastic industry, on their fate once microplastics dispose into the environment, and on their consequent effects on human health when associated with micro and nanoplastics. The present study emphasizes the most toxic and dangerous chemical substances that are contained in all plastic products to describe the effects and implications of these hazardous chemicals on human health, providing a detailed overview of studies that have investigated their abundance on microplastics. In the present work, we conducted a capillary review of the literature on micro and nanoplastic exposure pathways and their potential risk to human health to summarize current knowledge with the intention of better focus future research in this area and fill knowledge gaps.
