Microplastic concentrations in lagoon, bay and beach environments of Binh Dinh province, Central Vietnam. COMPOSE (2019-2021) and CounterMEASUREII (2021-2022) projects
Summary
Microplastic concentrations were measured in lagoon, bay, and beach environments in Binh Dinh province, Vietnam, across multiple sampling campaigns from 2019 to 2022. The study provides baseline contamination data for a Central Vietnamese coastal region under pressure from fisheries and aquaculture activities.
Microplastic (300-5000µm) concentrations were measured in the Thi Nai lagoon, Quy Nhon bay and beach, Ha Tay River, Kon River, Cat Tien beach and Eo beach environments of Binh Dinh province, Central 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, April 2020, July 2020, October 2020, January 2021 and March 2021 under COMPOSE Project; September 2021, October 2021 and January 2022 under the CounterMEASUREII project.
