My PhD project is investigating the microplastic pollution in Vietnamese beaches and the role of benthos which is divided into two tasks. Task 1: We first will do a field study to investigate the microplastic concentrations in the sediment and in benthos on Vietnamese beaches in natural conditions. Task 2: We will then study the role of benthos as a vector for microplastic by means of experiments to identify their potential functions of (micro)plastic accumulation and removal and burial rate in the sediments.
