Data for: Pesticide Risks in Small Streams - How to Get as Close as Possible to the Stress Imposed on Aquatic Organisms

The dataset contains concentrations profiles of 213 agricultural pesticides in surface water samples. Half-day composite samples were taken from five small streams in Switzerland from the beginning of March to the end of August 2015. Half-day samples from discharge events were measured individually, whereas half-day samples taken during dry weather periods between discharge events were pooled to samples of variable lengths (five days on average) and then measured resulting in 34 to 60 measured samples per site.

本数据集包含213种农用杀虫剂在地表水样品中的浓度剖面。2015年3月初至8月末，研究人员从瑞士的5条小型溪流中采集半日混合样品。其中，径流事件期间采集的半日样品单独开展检测；而径流事件间隔的干燥天气时段采集的半日样品则被合并为时长不等的混合样品（平均时长为5天）后再进行检测，最终每个采样点可获得34至60个实测样品。
