Microplastic concentrations in surface waters of Dau Tieng and Tri an reservoirs

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.
