Initial survey on microplastic waste in coastal water in Nam Dinh

Plastic materials are defined as including the whole of organic polymers owning plasticity. Their production increases rapidly due to their superior properties and applications in our life. Currently, annual plastic is estimated at nearly 400 million tons. About 10% produced discharged into seas oceans. Microplastics (MP, less than 5 mm size) non-biodegradable persistent environment have ability accumulate various environmental components, organisms other human beings through food chain. Therefore, assessing microplastic pollution becomes essential for marine ocean environment. This study aims evaluate Nam Dinh seawater. Water samples were taken summer 2020 spring 2021 Giao Thuy district, province. Samples treated with 30% H2O2 solution remove matters then buoyantly separated using saturated NaCl solution. MP was identified observation under a stereo microscope (Olympus SZX2-TR300) its nature determined infrared spectroscopy (µFTIR). Results show that large level (average 6 8 particles/m3 10–14 particles/km2) associated predominant colored fibers among characteristics. Most microplastics Polypropylene nature. Next, more research needs be invested this problem, such expanding scope object.
