| Abstract | Microplastic pollution (plastic debris < 5 mm) has become a global environmentalproblem due to the accumulation of plastic debris in water bodies over the decades.The present study was conducted to determine the abundance, shape, color, size, andcomposition of microplastics in the sand collected at recreational beaches in VungTau city of Vietnam. Ten sand samples were collected, five from Front Beach and fivefrom Back Beach. These samples were extracted and analyzed for microplastics witha dissecting microscope, Nile red staining and the Fourier Transform Infrared (FTIR)technique. Results showed that microplastics were present in all study areas, withconcentrations ranging from 5 to 27 MPs/100 g of dry sand. Colored and fibers dominatedin both beaches (70-80%), of which fibers shorter than 0.5 mm were commonly found.Many detected microplastics were black and blue with a similar percentage, 32.55 %and 34.66 %. The predominant microplastics were polyethylene (PE) and polypropylene(PP). The study proved the efficacy of Nile Red with FTIR in quantifying microplasticsin the sand samples. The results alert the wide spreading of plastic debris along thebeaches, which poses many risks to human entertainment activities and local ecosystems. |
