摘要

背景杀虫剂的过度使用是影响环境和人类健康的一个重大全球性问题。阿特拉津(ATR)是一种合成三嗪类除草剂,通常用于管理农作物,虽然多年前就已被禁用,但在水生环境中仍经常被检测到,且具有很高的持久性。这项研究评估了南欧塞勒河河口 ATR 及其降解产物(DPs)对人类和环境造成的健康风险、时间模式和空间分布。结果在一年四季的 10 个地点进行了采样。在水溶相(WDP)中检测到的 ATR 及其 DPs 的含量为 20.1 至 96.5 纳克/升,在悬浮颗粒物(SPM)中检测到的 ATR 及其 DPs 的含量为 5.4 至 60.2 纳克/升,在沉积物样品中检测到的 ATR 及其 DPs 的含量为 4.7 至 19.8 纳克/克,表明污染程度达到了一定程度。空间分布机制揭示了 ATR 及其 DPs 污染从 Sele 河口向南移动,并在雨季加剧。在该研究区域还进行了风险评估。样本中的 ATR 或其二磷酸浓度均未超过建议限值,因此不存在致癌和致癌风险。环境风险较低。此外,确定的增量终生致癌风险 (ILCR) 值也在允许范围之内。这项研究不仅描绘了塞勒河的污染状况,还描绘了其对蒂勒尼安海的生态影响,为与水污染相关的规范和法律提供了重要数据。

Assessment of atrazine contamination in the Sele River estuary: spatial distribution, human health risks, and ecological implications in Southern Europe

Background

Overuse of pesticides is a major worldwide problem for the environment and human health. Atrazine (ATR) is a synthetic triazine herbicide that is typically used to manage crops and although it was banned many years ago, it was detected frequently with a high persistence in the aquatic environments. This study assesses the human and environment health risks, temporal patterns and spatial distribution of ATR and its degradation products (DPs) in the Sele River estuary within the Southern European context.. It specifically investigates their occurrence in the water dissolved phase (WDP), suspended particulate matter (SPM), and sediment.

Results

Sampling was conducted across 10 sites throughout the year’s four seasons. Amounts of ATR and its DPs detected ranged from 20.1 to 96.5 ng L−1 in WDP, from 5.4 to 60.2 ng L−1 in SPM, and from 4.7 to 19.8 ng g−1 in sediment samples, signifying some pollution levels. Spatial distribution mechanisms revealed a southward movement of ATR and its DPs pollution from the Sele River mouth, intensifying during the rainy season. In this study area, a risk evaluation was also carried out. No sample contained ATR or its DPs in concentrations above the recommended limits, which pose a Non-carcinogenic and Carcinogenic risk. The environmental risk was low. Additionally, the determined Incremental lifetime cancer risk (ILCR) value was within the allowable range.

Conclusion

Despite its long-standing prohibition, this study investigate ATR levels in the water and sediments of Sele River in Southern Europe. Beyond simply delineating the pollution status of Sele River, this research delineates its ecological repercussions on the Thyrrenian Sea, providing essential data for norms and laws related to water contamination.

期刊介绍: ESEU is an international journal, focusing primarily on Europe, with a broad scope covering all aspects of environmental sciences, including the main topic regulation. ESEU will discuss the entanglement between environmental sciences and regulation because, in recent years, there have been misunderstandings and even disagreement between stakeholders in these two areas. ESEU will help to improve the comprehension of issues between environmental sciences and regulation. ESEU will be an outlet from the German-speaking (DACH) countries to Europe and an inlet from Europe to the DACH countries regarding environmental sciences and regulation. Moreover, ESEU will facilitate the exchange of ideas and interaction between Europe and the DACH countries regarding environmental regulatory issues. Although Europe is at the center of ESEU, the journal will not exclude the rest of the world, because regulatory issues pertaining to environmental sciences can be fully seen only from a global perspective.
