Description
Microplastic (300-5000µm) concentrations were measured in the Cua Luc Bay and Ha Long Bay of Quang Ninh province and in the Do Son Bay, Cat Ba Bay, Lach Tray River and Cam River of Hai Phong province, Northern Vietnam,, under the COMPOSE project (2019-2021)and the CounterMEASUREII project (2021-2022).

Microplastic were sampled using a 80µm mesh size net from a local boat. The samples were extracted in the laboratory using enzymatic digestion, NaCl density separation and were filtrated on GF-A filter. Then microplastic were observed on stereomicroscope and length, area, color were measured for fragments, line and circle. Concentrations are given in total microplastic per m3, fragment per m3 and fibers per m3.

The sampling dates are October 2019, January 2020, May 2020, July 2020, October 2020, January 2021, October 2021 and January 2022
