摘要

塑料在许多方面改善了人类的生活条件。然而,研究表明,人体组织中塑料颗粒的污染会导致严重的健康问题,反映了塑料废物管理不当的不可预见的后果。微纳米塑料(MNP)污染已成为全球环境和健康科学家关注的问题。然而,目前的水处理方法缺乏具体的过程来消除水中的塑料残留物。瓶装饮料市场的增长进一步引发了人们对日常生活中存在的塑料颗粒的担忧。在这项研究中,我们报告了对越南非酒精饮料中塑料污染的调查,包括瓶装水、软饮料和茶。作为一个发展中国家,越南受到塑料污染的严重影响,缺乏足够的资源来评估污染的程度。利用纳米颗粒分析仪检测液体溶液中的颗粒,确定了样品中MNP的数量和大小。结果表明,瓶装水平均含4.6 × 106纳米塑料/mL、1.76 × 107微塑料/mL,含糖饮料平均含1.91 × 108纳米塑料/mL、1.27 × 109微塑料/mL。这些颗粒的大小和形状变化很大,表明可能有多种来源的污染。这是第一个调查越南饮料中MNP分布的研究。虽然无法确定污染源,但研究结果引起了人们对潜在水污染和与生产有关的问题的关注。

Micro-and nanoplastic contamination in beverages in Vietnam

Plastic has improved human living conditions in many ways. However, studies have shown that the contamination of plastic particles in human tissue can cause serious health issues, reflecting the unforeseen consequences of improper plastic waste management. Micro- and nanoplastic (MNP) contamination has become a global concern for environmental and health scientists. However, current water treatment methods lack specific processes to eliminate plastic residues from water. The growing market for bottled drinks further raises concerns about the presence of plastic particles in daily human life. In this study, we report an investigation into plastic contamination in non-alcoholic beverages in Vietnam, including bottled water, soft drinks, and teas. As a developing country, Vietnam is severely affected by plastic pollution and lacks adequate resources to assess the extent of the contamination. Using a nanoparticle analyzer to detect particles in the liquid solutions, the number and size of MNP in the collected samples were identified. The results showed that bottled water contained an average of 4.6 × 106 nanoplastic/mL, and 1.76 × 107 microplastic/mL, while sugary drinks contained 1.91 × 108 nanoplastic/mL and 1.27 × 109 microplastic/mL. The sizes and shapes of these particles varied greatly, suggesting possible contamination from multiple sources. This is the first study to investigate the distribution of MNP in beverages in Vietnam. Although the sources of contamination could not be identified, the findings raise concerns about potential water pollution and production-related issues.
