Monitoring of microplastics in road dust samples from Myanmar and Taiwan

Abstract: Microplastics (MPs) are ubiquitous pollutants in various environmental matrices. In this study, 82 road dust samples collected from Myanmar and Taiwan between 2014 and 2018 were analyzed to investigate the status of MPs pollution and distribution. In Myanmar, the mean abundances of MPs in road dust were high in cities, such as Nay Pyi Taw (285 pieces /kg dry weight), Mandalay (79 pieces/ kg), and Yangon (63 pieces / kg). Alternatively, no MPs were found in samples from the rural areas, Wundwin and Bagan. The m… Show more

“…During the without lockdown condition, PP was the most abundant in industrial areas (19%) and commercial areas (25%), while fiber (32%) and cellulose (21%) were the most abundant MPs in public facilities and residential areas (Figure S1). This result for industrial areas agrees with [49], who found that polypropylene (PP) was the dominant polymer detected in road dust in an industrial area in Myanmar. During partial lockdown, PP was still the most abundant in the industrial area (20%), while PDMS (17%) was the most abundant in commercial areas.…”

“…The unique properties of this polymer, including excellent mechanical strength, durability, stability, chemical resistance, and insulation, make it a popular material in various industries, such as electronics, automotive, and consumer goods. It is also utilized in medical applications, such as surgical implants, drug-delivery systems, and medical devices, as described in studies by Król-Morkisz et al [48] and Tang et al [49]. In Figure 6, the quantity of MP types in the street dust from different land-use categories during the different lockdown conditions is presented.…”

“…When comparing results on DSS samples in Indonesia [6], which also used NaI as the solvent, a similar count of 10,929 pieces kg -1 is observed. Regarding RDS samples, a comparison with average values from urban communities in Nay Pyi Taw, Myanmar (285 pieces kg -1 ), and Tokyo, Japan (230 pieces kg -1 ) [18,20] indicates that the MP count in this study is approximately three times higher.…”

“…Accordingly, road dust is recognized as one of the major sources of MPs pollution among the several forms of MPs pollution (Roychand and Pramanik, 2020). Worldwide reports of MPs in road dust have already been made and studied by the many other countries such as in Australia (Monira et al, 2022;O'Brien et al, 2021;Su et al, 2020), Germany (Dierkes et al, 2019), Sweden (Järlskog et al, 2020, Iran (Abbasi et al, 2019(Abbasi et al, , 2017, and in Asia such as China (Zhang et al, 2022), India (Patchaiyappan et al, 2021), Japan, Nepal, Vietnam (Yukioka et al, 2020) and, in Myanmar and Taiwan (Mon et al 2022), but there were no studies in the Philippines ever recorded for.…”
