Microplastics have recently emerged as a significant environmental concern due to their direct impacts on marine ecosystems. Vietnam, with its 3260-km coastline, faces an elevated risk of microplastic pollution due to various coastal anthropogenic activities. This study explored microplastic distribution in coastal surface seawater in the Southern Vietnam regions of Tien Giang, Can Gio, and Vung Tau. A total of 45 samples were collected in April, 2019, and the results showed that microplastics present at all sampling sites, with the abundance varying from 0.074 ± 0.109 pieces/m in Can Gio to 0.56 ± 0.35 pieces/m in Tien Giang. Estuarial sites showed higher abundances for all regions. Most microplastics were under 2.8 mm, fragmented, and primarily white or transparent. Polypropylene, polyethylene, and ethylene-vinyl acetate were the dominant polymers. This research indicates the urgency of further investigations to comprehensively understand the influence of wind patterns and other environmental factors on microplastic distribution.
微塑料最近因其对海洋生态系统的直接影响而成为一个重大的环境问题。越南拥有 3260 公里的海岸线，由于各种沿海人为活动，面临着更高的微塑料污染风险。本研究探讨了越南南部地区的天江、甘吉和头顿的沿海表层海水中的微塑料分布。于 2019 年 4 月共采集了 45 个样本，结果表明，所有采样点均存在微塑料，丰度从甘吉的 0.074±0.109 片/米到天江的 0.56±0.35 片/米不等。所有地区的河口点都显示出更高的丰度。大多数微塑料的尺寸小于 2.8 毫米，呈碎片状，主要为白色或透明。聚丙烯、聚乙烯和乙烯-醋酸乙烯酯是主要的聚合物。这项研究表明，需要进一步调查以全面了解风场和其他环境因素对微塑料分布的影响。
