STUDY ON STATUS AND IMPACT ASSESSMENT OF MICROPLASTICS IN COASTAL SEDIMENTS TO THE ENVIRONMENT AND ECOSYSTEM IN CAT BA COASTAL AREA

Abstract

In this work, sediment samples were collected from the beach area and the coastal aquaculture area of Cat Ba. Analytical methods of microplastics in sediments were conducted under the guidance of the US Oceanic and Atmospheric Administration NOAA. The results showed that the microplastics content in sediments in the coastal area of Cat Ba at sampling locations ranged from 7.2 ± 1.3 to 21.0 ±11.1 mg/kg with the value of average 12.1 ± 8.9 mg/ kg. The amount of microplastic in sediment has uneven distribution between sampling points. The study also reviews and evaluates the effects of microplastics in sediments on the environment and regional ecology.
