Abstract
Microplastics are found in all aquatic environments, and they can have several negative impacts on marine life. In this study, the distribution of microplastics in the sediment and in the organs (gut, respiratory tree, and tentacles) of sea cucumber (Holothuria leucospilota) collected from Mubarak Village and Cape Monze on the Karachi coast of Pakistan were investigated. The microplastic amount in different organs of H. leucospilota was found as 15.3-40.45 pieces/individual in the gut, 15.45-23.9 pieces/individual in the respiratory tree, 8.9-9.55 pieces/individual in tentacles. The microplastic amount of sediment samples was 57.40-129.35 pieces/kg. Fibers were the dominant microplastic type, up to 99% of all samples. The results of the present study show that the region is contaminated with microplastics both in biota and in sediments.
