Abstract

The presence of microplastics (MPs) in aquatic environments has become a significant global concern due to their potential adverse effects on human health. This study aimed to investigate the contamination of MPs throughout the drinking water supply chain in Haikou City, China, and to conduct risk assessments regarding the relationship between MPs contamination and human health. The results revealed that the abundance of MPs in raw, treated, and tap water was 0.6 ± 0.6, 5.2 ± 2.7, and 1.2 ± 1.1 particles·L^-1, respectively. Fragments were identified as the most prevalent shape across all samples, with the size category of 20-50 μm showing the highest abundance of MPs. Among the 11 types of polymers identified, polyethylene and polypropylene accounted for 50% and 29%, respectively. The potential risk index values were significantly higher for treated water (370.26) and tap water (303.85) compared to raw water (13.46), suggesting that plastic pipes may be a key contributor to MPs contamination in drinking water. Therefore, efforts should be directed toward developing pipes with low release rates of MPs, as well as improving detection methods for smaller particles and accurately assessing associated risks.

追踪中国海口饮用水供应链中的微塑料污染：从水源到家庭水龙头。

水生环境中存在的微塑料（MPs）因其对人类健康的潜在不利影响而成为全球关注的一个重要问题。本研究旨在调查中国海口市饮用水供应链中的微塑料污染情况，并就微塑料污染与人体健康之间的关系进行风险评估。结果显示，原水、处理水和自来水中 MPs 的丰度分别为 0.6 ± 0.6、5.2 ± 2.7 和 1.2 ± 1.1 粒子-L-1。在所有样本中，碎片是最常见的形状，其中 20-50 μm 尺寸类别的多孔质颗粒含量最高。在鉴定出的 11 种聚合物中，聚乙烯和聚丙烯分别占 50%和 29%。与原水（13.46）相比，经过处理的水（370.26）和自来水（303.85）的潜在风险指数值明显更高，这表明塑料管道可能是造成饮用水中 MPs 污染的主要因素。因此，应努力开发 MPs 释放率低的管材，同时改进较小颗粒的检测方法，并准确评估相关风险。

期刊介绍： Toxics (ISSN 2305-6304) is an international, peer-reviewed, open access journal which provides an advanced forum for studies related to all aspects of toxic chemicals and materials. It publishes reviews, regular research papers, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in detail. There is, therefore, no restriction on the maximum length of the papers, although authors should write their papers in a clear and concise way. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of calculations and experimental procedure can be deposited as supplementary material, if it is not possible to publish them along with the text.
