Abstract A total of 59 current-use pesticides were monitored in ambient air samples collected from February 2012 to December 2017, at two rural and six urban sites in Provence-Alpes-Cote-d’Azur Region and Corsica, France. 45 of searched active substances were detected at least in one sample, at frequencies ranging from 0.1 to 98.6%. Among the most frequently detected pesticides, we found the herbicide Pendimethalin (64.6%), the fungicide Tebuconazole (65.9%), and the insecticides Chlorpyrifos (71.5%) and Lindane (98.6%). A wide range of atmospheric concentrations was measured from few pg m−3 to several hundreds of ng m−3, with a maximum concentration of 407.79 ng m−3 for Chlorpyrifos (Cavaillon, May 2012). 17 active substances exceeded an atmospheric concentration of 1 ng m−3 for at least one sample, including Folpet (147 times/162 detections), Chlorpyrifos (56/520), and Pendimethalin (29/464). The spatial distribution shows that pesticides were detected both in the eight rural and urban sampling sites, suggesting an atmospheric transport from agricultural areas to cities. Classifying the 8 sampling sites according to samples composition, two types of site were observed, those (Aleria, Arles, Avignon, Port-de-Bouc, and Toulon) where a majority of fungicides are found and those (Cannes, Cavaillon, and Nice) where insecticides are dominant. Long-term (6 years) monitoring shows a seasonally trend for each pesticide, depending on pest pressure. Inter-annual variation suggests a downward trend which is consistent with the regional sales data.

法国普罗旺斯-阿尔卑斯-蓝色海岸地区和科西嘉岛环境空气中现用农药的时空分布

摘要 2012 年 2 月至 2017 年 12 月,在法国普罗旺斯-阿尔卑斯-蓝色海岸地区和科西嘉岛的两个农村和六个城市地点收集的环境空气样本中,共监测了 59 种当前使用的农药。至少在一个样品中检测到 45 种被搜索的活性物质,频率范围从 0.1% 到 98.6%。在最常检测到的农药中,我们发现了除草剂二甲戊灵 (64.6%)、杀菌剂戊唑醇 (65.9%) 以及杀虫剂毒死蜱 (71.5%) 和林丹 (98.6%)。测量的大气浓度范围很广,从几 pg m-3 到数百 ng m-3,毒死蜱的最大浓度为 407.79 ng m-3(Cavaillon,2012 年 5 月)。至少一个样品的 17 种活性物质超过 1 ng m-3 的大气浓度,包括 Folpet(147 次/162 次检测),毒死蜱 (56/520) 和二甲戊灵 (29/464)。空间分布显示,8 个农村和城市采样点均检测到农药,表明存在从农业区到城市的大气迁移。根据样本组成对 8 个采样点进行分类,观察到两种类型的地点,即发现大多数杀菌剂的地点(Aleria、Arles、Avignon、Port-de-Bouc 和 Toulon)和那些(戛纳、Cavaillon 和 Nice) ) 杀虫剂占主导地位的地方。长期(6 年)监测显示每种农药的季节性趋势,这取决于害虫压力。年际变化表明呈下降趋势,与区域销售数据一致。空间分布显示,8 个农村和城市采样点均检测到农药,表明存在从农业区到城市的大气迁移。根据样本组成对 8 个采样点进行分类,观察到两种类型的地点,即发现大多数杀菌剂的地点(Aleria、Arles、Avignon、Port-de-Bouc 和 Toulon)和那些(戛纳、Cavaillon 和 Nice) ) 杀虫剂占主导地位的地方。长期(6 年)监测显示每种农药的季节性趋势,这取决于害虫压力。年际变化表明呈下降趋势,与区域销售数据一致。空间分布显示,8 个农村和城市采样点均检测到农药,表明存在从农业区到城市的大气迁移。根据样本组成对 8 个采样点进行分类,观察到两种类型的地点,即发现大多数杀菌剂的地点(Aleria、Arles、Avignon、Port-de-Bouc 和 Toulon)和那些(戛纳、Cavaillon 和 Nice) ) 杀虫剂占主导地位的地方。长期(6 年)监测显示每种农药的季节性趋势,这取决于害虫压力。年际变化表明呈下降趋势,与区域销售数据一致。Avignon、Port-de-Bouc 和 Toulon),那里发现了大多数杀菌剂,而那些(戛纳、卡瓦永和尼斯)则杀虫剂占主导地位。长期(6 年)监测显示每种农药的季节性趋势,这取决于害虫压力。年际变化表明呈下降趋势,与区域销售数据一致。Avignon、Port-de-Bouc 和 Toulon),那里发现了大多数杀菌剂,而那些(戛纳、卡瓦永和尼斯)则杀虫剂占主导地位。长期(6 年)监测显示每种农药的季节性趋势,这取决于害虫压力。年际变化表明呈下降趋势,与区域销售数据一致。
