This study aims at understanding the presence of regulated and emerging micropollutants, particularly pesticides and pharmaceuticals, in surface water, regarding spatial and temporal influences at a watershed scale. The study of relations between micropollutants and other water quality and hydroclimatic parameters was carried out from a statistical analysis on historical and experimental data of different sampling sites from the main watershed of Brittany, western France. The outcomes point out the influence of urban and rural areas of the watershed as well as the impact of seasons on contamination variations. This work contributes to health risk assessment related to surface water contamination by micropollutants. This approach is particularly interesting in the case of agricultural watersheds such as the one studied, where more than 80% of surface water is used to produce drinking water.
本研究旨在了解特定流域范围内，受管制和新兴的微污染物（特别是农药和药物）在地表水中的存在情况，及其时空分布影响。通过对法国西部布列塔尼主要流域不同采样点的历史和实验数据进行统计分析，研究了微污染物与其他水质和水文气候参数之间的关系。研究结果表明，流域的城乡地区以及季节变化对污染变化都有影响。本研究有助于评估与地表水中微污染物污染相关的健康风险。对于像所研究的那样的农业流域，这种方法特别有趣，因为超过 80%的地表水用于生产饮用水。
