The observation and direct sampling, as well as laboratory tests of this research was conducted from June until October 2018. This study aims to determine the existence of microplastics in the sediment of water bodies in Kupang and Rote Districts based on the number, type, size and abundance of microplastics. The data used in this study include the type of sediment, microplastic abundance and the characteristics of the data collection area. Microplastics are plastic particles sized less than 5 mm, and in our research, were divided into 4 types: manifold fiber, fragment, film and pellets. Herein, 849 particles of microplastic were found: 635 fibers, 160 particle fragments, and 54 particle films. The primary influencing factor for microplastic deposition is the sedimentary texture itself. Sediments of a coarse type do not capture as much microplastic as do sediments of a finer texture. Data collection area characteristics also affect accumulation.

The distribution and extent of heavy metal accumulation in the fluvial sediment of the Beijiang River are described. The potential toxicity of this pollution was quantified using a consensus based sediment quality guidelines (SQGs) method and the Hakanson potential ecological risk index. The concentrations of Hg, As, Cu, Zn, Pb, Ni and Cr were high enough to damage the sediment biota on a frequent basis. The potential ecological risk was much higher in the downstream, urbanized reaches of the river than in the upstream reaches which are still rural, but all sections of the river posed at least a moderate level of ecological risk. Estimates of the economic loss associated with these pollutions were appreciable, and were mainly due to Hg and Cu. The Beijiang River basin is heavily polluted, posing environmental risks for the downstream reaches of the Pearl River, and economic loss to the whole watershed.
