Microplastic pollution has emerged as a new global concern because of its ubiquitous and persistent nature. Due to the rising use of plastics and discharge of plastic waste into coastal water bodies from point and non-point sources, the occurrence of microplastics along coastal ecosystems has become very prevalent. The current study is the first of its kind to evaluate the presence of microplastics in the surface water of river estuary along the coast of Odisha. Six GPS-fixed locations were used to collect the surface water samples from the Budhabalanga river estuary in Chandipur, Odisha, India. The samples were then subjected to further investigation to determine the types of microplastics present. The average microplastic abundance, according to our findings, ranged from 9.33 ± 2.11 items L
