| Abstract | Round scad is the common dish often consumed in Central Vietnam because of its low price, easy-catching, and high nutritional value. In this study, microdebris includes all synthetic, semi-synthetic, and naturally-derived items extracted from the tissues. The accuracy of the analytical procedure including digestion and polymer flotation methods was tested through the analysis of standardized polymers. The recoveries of polypropylene, polyethylene, polyethylene terephthalate, polyamide and polycarbonate ranged from 94 to 102%. The degree of digestion efficiency in this study was very high, reaching 95 to 99 %. The numbers of microdebris determined in round scad from Phu Yen province and Thua Thien Hue province were 0.9 ? 0.4 and 1.1 ? 0.5 items/g-wet weight and 87 ? 43 and 71 ? 32 items/individual respectively. Only fibers and fragments were found as microdebris in the samples, in which the microfibers were the most commonly-found type with 63% and 89% in samples collected from Thua Thien Hue and Phu Yen provinces, respectively. The level of microdebris accumulated in round scad was relatively high compared with the ranges reported in the literature, suggesting a potentially high risk of humans consuming round scad as daily food. |
