**6. Conclusion and recommendation**

This study is the first study to measure microplastic pollution in the sediment of the eastern coast of the kingdom of Saudi Arabia. The common size of microplastic particles measured (77%) was less than 2 mm in size. Microplastic abundance within the study sites ranged from 5.5 to 21.2 particles/kg (51.1 to 152.8) in the low tide region, and from 6.3 to 16.5 particles/kg (50.6 to 204.5 particles/m2 ) in the high tide region. The main goal of this study is to provide a baseline and glimpse of the quantity and identity of microplastic in our selected sites, however, those values consider to be a baseline for a coast length of 800 km. The future researcher will have some expectations of microplastic distribution along this coastline. Several recommendations can be suggested to whom is interested in curry microplastic research on Saudi Arabia's eastern coast:
