Description 574-584
Microplastics are a class of emerging pollutants of concern detected in beach sediments across the globe. Limited
research on the topic has been undertaken in India, despite extensive coastlines and the country's most crowded beaches. The
present study is a preliminary study on the quantification and characterization of microplastics in one of the most famous
tourist destinations, the Golden beach of Puri, Odisha. An average count of 731±719 particles/kg dry weight of sediment
was observed. Though ANOVA revealed a site-wise variation of microplastic types to be significantly different, Tukey
posthoc test of the particle’s diversity classified according to their major activity contributors did not show significant
variation. The fragments were the most abundant fraction with a total count of 2835 particles representing 39 % of the total
microplastics, followed by foams (29 %), fibers (14 %), films (11 % ), microbeads (5 %), and pellets (2 %) of the total
microplastic particles. Color classification revealed white, red, black, blue, green, and transparent microplastics to be
abundant in all the sampling sites. Polymer characterization showed the presence of seven types of polymers being,
High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Polyurethane (PU), Polypropylene (PP),
Polystyrene (PS), Ethylene-Vinyl Acetate (EVA), and Nylon. These preliminary findings would serve as an eye-opener
toward the magnitude of microplastic pollution in the area and help opt for mitigatory measures to avoid further detrimental
impacts on the ecosystem.
