This study measured both nutrient and pesticide concentrations at up to 13 different freshwater stream sites in New Brunswick, Nova Scotia and Prince Edward Island between 2013 and 2018. Up to 62 different pesticides were analysed in 248 discreet samples. A large majority of pesticides were below the detection limit of the laboratory while seven pesticides had at least 20% or more detections throughout the years of this study. The four pesticides that had the highest frequency of detection were the insecticides chlorantraniliprole, clothianidin, imidacloprid, and thiamethoxam of which the last three are categorised as neonicotinoid insecticides.
本研究在 2013 年至 2018 年间对新不伦瑞克省、新斯科舍省和爱德华王子岛的多达 13 个不同的淡水溪流地点进行了营养物和农药浓度的测量。在 248 个离散样本中分析了多达 62 种不同的农药。绝大多数农药的实验室检测限以下，而在本研究的几年中，有 7 种农药的检测率至少达到 20%或更高。检测频率最高的四种农药是杀虫剂氯虫苯甲酰胺、噻虫啉、吡虫啉和噻虫嗪，后三种被归类为新烟碱类杀虫剂。
