Microplastic concentrations in riverine and beach environments of Ba Ria Vung Tau province, Southern Vietnam, under COMPOSE (2019-2021) and CounterMEASUREII (2021-2022) projects

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, April 2020, July 2020, October 2020, January 2021 and March 2021 under COMPOSE Project ; January 2022 under the CounterMEASUREII project.
