The aim of this is study to analyze and compare the amount of microplastics in the surface water and water column samples at Han River estuary (Da Nang) in the rainy season 2023. Sixteen water samples (eight water column samples and eight surface water samples) were collected and analyzed to determine the quantity, shape, color, size, and polymer forms of microplastics.

Microplastics are regarded as an emerging threat to water and other environments. The increasing use of plastics in agricultural cultivation has led to higher risks and more dangerous pollution of agricultural water. However, microplastics in agricultural water in Vietnam have neither been studied nor documented in any publication.
