“…For instance, hydrophobins are amphiphilic proteins ubiquitous in soils that are secreted by fungi (Rillig, 2005 (Steinmetz et al, 2016), ingestion by terrestrial and continental birds (Gil-Delgado et al, 2017;Holland et al, 2016;Zhao et al, 2016), reduction in growth of earthworms (Lwanga et al, 2016), lethal toxicity to fungi (Miyazaki et al, 2014(Miyazaki et al, , 2015Nomura et al, 2016), mammal lung inflammation (Hamoir et al, 2003;Oberdorster, 2000;Schmid & Stoeger, 2016) and broad cytotoxicity (Forte et al, 2016;Kato et al, 2003) of nanoplastics [Colour figure can be viewed at wileyonlinelibrary.com] stability, with direct potential consequences for soil erosion and biogeochemical cycles (Rillig, 2005). It was suggested that microplastics might present distinct sorption properties for soil inorganic elements (Hodson, Duffus-Hodson, Clark, Prendergast-Miller, & Thorpe, 2017), and laboratory results suggest that hydrophobins play a role in the protection against nanoplastic toxicity to filamentous fungi (Nomura et al, 2016). Relevant biogeochemical changes might arise if the hydrophobic surfaces of microplastics interact with hydrophobins or other chemical drivers of soil structure in a manner significantly different from natural soil particles.…”

“…Reported processes (Kato et al, 2003;Miyazaki et al, 2014Miyazaki et al, , 2015Syberg et al, 2015) do not fully explain toxicity and uptake. Further mechanisms await discovery [Colour figure can be viewed at wileyonlinelibrary.com] 2014; Nomura et al, 2016). The uptake of nanoplastics through chitin-rich fungi cell walls highlights their capacity of crossing important impermeable barriers for many other toxics.…”

Microplastics (plastics <5 mm, including nanoplastics which are <0.1 μm) originate from the fragmentation of large plastic litter or from direct environmental emission. Their potential impacts in terrestrial ecosystems remain largely unexplored despite numerous reported effects on marine organisms. Most plastics arriving in the oceans were produced, used, and often disposed on land. Hence, it is within terrestrial systems that microplastics might first interact with biota eliciting ecologically relevant impacts. This article introduces the pervasive microplastic contamination as a potential agent of global change in terrestrial systems, highlights the physical and chemical nature of the respective observed effects, and discusses the broad toxicity of nanoplastics derived from plastic breakdown. Making relevant links to the fate of microplastics in aquatic continental systems, we here present new insights into the mechanisms of impacts on terrestrial geochemistry, the biophysical environment, and ecotoxicology. Broad changes in continental environments are possible even in particle-rich habitats such as soils. Furthermore, there is a growing body of evidence indicating that microplastics interact with terrestrial organisms that mediate essential ecosystem services and functions, such as soil dwelling invertebrates, terrestrial fungi, and plant-pollinators. Therefore, research is needed to clarify the terrestrial fate and effects of microplastics. We suggest that due to the widespread presence, environmental persistence, and various interactions with continental biota, microplastic pollution might represent an emerging global change threat to terrestrial ecosystems.

“…Nomura et al demonstrated that nanoplastics made of polystyrene latex were taken up internally by Aspergillus oryzae but not by Aspergillus nidulans in liquid culture (Nomura et al 2016). Over time, hypha of both fungi were coated by the nanoplastics, which led to cell death.…”

The massive scope of plastic and microplastic pollution in soils and sediments requires broad and thorough studies to understand details of the extent and effects of these persistent pollutants. Plastic particulate pollutants in the environment are subjected to natural processes, fragment over time into smaller pieces, and influence the surrounding biota. Land environments, from open fields to agricultural fields to watersheds and deep ocean sediment, have been subjected to plastics/microplastics from a variety of sources and via natural and anthropogenic transport for many years. A number of different sampling, processing, and detection methods have been used to identify and quantify the loads of microplastics in soils and sediments. Scientific studies are still lacking systematic, standardized protocols, which will allow for accurate comparisons and compilations of data from around the world. This review chapter highlights many studies published over the past several years on land environments affected by

“…The prevalence of microplastics (MPs) has been recently recognized as a threat to the biosphere owing to their infinitesimal size responsible for highly stable nature towards natural degradation processes [1,2], thereby related adverse effects have been reported across all over ecosystems from low to high trophic levels of food chain: microorganisms [3][4][5], plants [6,7], animals [8][9][10][11], and even human beings [12]. These significant ecological impacts persuade the researchers to investigate the aging behavior of these tiny particles in an environment.…”

Microplastics coexist with the chemical reactive oxygen species in natural waters, however, there is still a lack to elucidate the effect of these radicals on the microplastic surficial oxidation. In this study, the ozonation of polyethylene microplastics was carried out under varying ozone dosages ranging from 4 to 7 mg/min for 60, 120 and 180 min, where its ozone uptake was iodometrically compared and surficial modification was spectroscopically analyzed using FTIR and XPS. For that, the lowest ozone uptake was 16% at 4 mg/min ozone supplied for 60 min whereas the highest was observed of 44% at 7 mg/min ozone added for 180 min. Moreover, in the FTIR analysis, carbonyl (1,600-1,800 cm-1) and hydroxyl (3,200-3,600 cm-1) indices were improved more than 20% and 13% when they were ozonized at 7 mg/min for 180 min compared to 4 mg/min for 60 min, respectively. XPS also revealed that 7 mg/min of ozone supplied for 180 min provided the highest of oxygen functionalities, but while there was no significant change in CC bond. It can be concluded that the surficial modification of PE including formation of oxygen functionalities could be more preferably influenced by the reaction time than ozone dosages.
