“…Consequently, if the sampling was conducted during the summer period, an increase in the amount of MP was likely due to the decrease in pond surface area. However, majority of the studies were conducted with a single sampling and widely available in the literature both for freshwater and marine ecosystems Yin et al, 2019;Scopetani et al, 2019;Wang et al, 2019;Egessa et al, 2020). Moreover, there is a possibility of error in the microscope identification.…”

Microplastic pollution has increased rapidly over recent decades and accepted as an emerging thread. However, the effects and dimensions of microplastic pollution on aquatic ecosystems have not been fully understood yet. Most of these few studies have been carried out in marine ecosystems and the number of studies on freshwater are very limited. In this study, microplastic (<5 mm) pollution level of surface water samples taken from Cevdet Pond (Yozgat/Turkey) was investigated. Water samples (150 L) were taken from 5 stations and microplastic particles were extracted via density separation method. Random particles were examined both visually and spectrophotometrically (µ-Raman). According to station averages, there were 233 microplastic particles in 1 m3 of the pond water. Highest number of MP particles observed in 100-250 µm (56%) size class. Most abundant microplastic type and colour are fiber (91%) and blue (36%) respectively. Polypropylene (50%) and polyethylene (40%) were the most abundant type of polymers according to µ-Raman analysis. The presence of microplastic pollution in an area where human impact is relatively low, indicates the prevalence of microplastic pollution in freshwater ecosystems.

“…Fenton's reagent (a mixture of H 2 O 2 and ferrous ions, Fe 2+ ) [27] and hydrogen peroxide (H 2 O 2 ) [115] have been widely used in digestion. When 4 ml 30% H 2 O 2 ias added to the samples for 7 days, 50%-56% of biogenic organic particles are in dissolution, while the remaining parts had chromogenic reactions such as semitransparent or partial dissolution.…”

Environmental Pollutants and Bioavailability

Although plastic materials play an essential role in life, the intensive production of plastic products and mismanagement of plastic waste worldwide have resulted in microplastic pollution. The two major characteristics of environmental microplastics are having small size and resistance to degradation, which make microplastics a persistent organic pollutant. As microplastic pollution has been observed in diverse environmental matrices, it has attracted great attention of scholars globally. Over the last decade, scholars have mainly documented the particle properties of microplastics, such as size, shape or color and their adverse effects on organisms. However, no research has updated on environmental microplastics from the perspective of multi-media. Our review first summarized the literature in the occurrence, distribution, and characteristics of microplastics in three kinds of environmental matrices (water, soil, and air) to the public. We then identify the methodological challenges in researches and discuss the advantages and limitations of popular methods to analyze environmental microplastics. Eventually, our paper highlights the current challenges and proposes suggestions for the future research on microplastic pollution.

“…Long before the world knew about COVID-19, millions of tons of plastic ended up daily in the sea with serious damage to the environment and with an unacceptable waste of precious resources (Haward 2018 ). Macroscopic residues from the degradation of common objects such as bottles or food packaging are only a small percentage of these wastes (Wang et al 2019 ; Tofa et al 2019 ). The main part is represented by micro- and nanoparticles, e.g., microplastics, produced by common operations such as the discharge of wastewater from our washing machines, the use of cosmetics and detergents, and the consumption of car tires (Padervand et al 2020 ; Naqash et al 2020 ).…”
