Abstract

The presence of highly toxic dioxins, specifically polychlorinated dibenzo-p-dioxins (PCDDs), in drinking water is a matter of great concern due to their long-lasting nature and harmful effects. In this study, we detected three out of the five dioxin congeners: 2, 3, 7, 8-tetrachlorodibenzodioxin (TCDD), 1, 2, 3, 7, 8-pentachlorodibenzo-p-dioxin (PeCDD), and octachlorodibenzo-p-dioxin (OCDD). The investigation revealed that three dioxins were present in water samples of winter season, while TCDD and OCDD were found in the summer season. The geometric mean concentrations of PCDDs were 229.9 ng/L (winter) and 108.4 ng/L (summer), exceeded the maximum contaminant level of 30 pg/L set by the USEPA in surface water. The estimated daily intake of PCDDs for residents through drinking water was 273.97 ng-WHO2005-TEQ/kg/days during winter and 78.875 ng-WHO2005-TEQ/kg/days during summer. Our study emphasizes the urgent need for further research on persistent organic pollutants in drinking water to safeguard public health and community well-being.

调查饮用水中是否含有二恶英：对公众健康的影响。

饮用水中含有剧毒的二恶英，特别是多氯二苯并对二恶英（PCDD），由于其持久性和有害影响，引起了人们的极大关注。在这项研究中，我们检测到了五种二恶英同系物中的三种：2, 3, 7, 8-四氯二苯并对二恶英（TCDD）、1, 2, 3, 7, 8-五氯二苯并对二恶英（PeCDD）和八氯二苯并对二恶英（OCDD）。调查显示，冬季水样中含有三种二恶英，而夏季水样中则含有三氯二苯并对二恶英和八氯二苯并对二恶英。多氯二苯并对二恶英的几何平均浓度分别为 229.9 纳克/升（冬季）和 108.4 纳克/升（夏季），超过了美国环保局规定的地表水最高污染物含量 30 皮克/升。据估计，居民每天从饮用水中摄入的多氯二苯并对二恶英含量为：冬季 273.97 纳克-WHO2005-TEQ/千克/天，夏季 78.875 纳克-WHO2005-TEQ/千克/天。我们的研究强调，迫切需要进一步研究饮用水中的持久性有机污染物，以保障公众健康和社区福祉。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
