Microplastics in three sandy beaches in Khanh Hoa province
Microplastics (MPs) are small plastic debris (< 5 mm) which pose negative impacts to marine ecosystems. This paper investigated microplastic abundance in 0–5 cm and 5–10 cm layers of three sandy beaches in Khanh Hoa province. The results showed that fiber was the most abundant microplastics in the samples, comprising 85% of the total microplastics. Fragment and film were reported with smaller percentages, over 10% and 2%, respectively. In addition, the effect of grain sizes on microplastic abundance in two sediment layers was also observed. At Doc Let and Cam Lam, sediments were mainly of fine grain sizes, microplastic concentrations decreased, when the sample depths increased. On the other hand, at Bach Dang, sediment sizes ranged from medium to coarse sizes, the difference of microplastic levels in two layers was not significant.
