Abstract
Data on the microplastic abundance in sea turtle nesting beaches of Southeast Asia are limited. We sampled four sea turtle nesting beaches in the northern and southern coastal areas of Terengganu, Malaysia between October and November 2018, to investigate microplastic abundance, shape, and colour at both high tide swash zone and dry dunes. Using optical observation, we isolated 2,489 microplastic items, belong to four types: Fibres, fragments, foam, and films. We found more microplastics at the high tide swash zone (58%) compared to the dune zone. Fibres were the most common shape (96.18%). Of the nine recognised colours found, black was the most abundant (35.64%) followed by transparent (24.53%). Of the sites investigated, those on the northern beaches had a higher abundance of microplastics. The causes of this difference were discussed. This study provides baseline data on microplastic contamination in Terengganu turtle nesting beaches. It highlights the need for further research to identify the effects on sea turtle nesting in this region
