The use of pesticides is associated with the decline of several avian species. In this study, we monitored the organochlorine contaminants in common swifts () in the years 2016 to 2018. These long-distance migrants breed in Europe and winter in Africa. Their only feeding source is aerial plankton. Pooled organ samples of 42 adult and 40 juvenile swifts were tested with the multi-residue method by gas chromatography-mass spectrometry (GC-TOF/MS). Predominantly, 4,4'-DDE, dieldrin, hexachlorobenzene (HCB), lindane and polychlorinated biphenyls (PCBs) were found in most of these common swifts. Only 4,4'-DDE (adult: 83 ± 70 μg/kg, juvenile: 17 ± 39 μg/kg) and dieldrin (adult: 2 ± 3 μg/kg, juvenile: 0.3 ± 1 μg/kg) concentrations were significantly different between adult and juvenile birds. All detected concentrations in our study were far lower than the previously recorded pesticide concentrations of common swifts in Italy and those which are known to cause toxicity and death in birds.
农药的使用与几种鸟类物种的数量减少有关。在本研究中，我们在2016年至2018年期间监测了普通雨燕（）体内的有机氯污染物。这些长途迁徙鸟类在欧洲繁殖，在非洲越冬。它们唯一的食物来源是空中浮游生物。采用气相色谱-飞行时间质谱联用仪（GC-TOF/MS）的多残留方法对42只成年雨燕和40只幼年雨燕的混合器官样本进行了检测。在大多数这些普通雨燕体内主要检测到了4,4'-滴滴伊、狄氏剂、六氯苯（HCB）、林丹和多氯联苯（PCBs）。仅4,4'-滴滴伊（成年鸟：83±70μg/kg，幼年鸟：17±39μg/kg）和狄氏剂（成年鸟：2±3μg/kg，幼年鸟：0.3±1μg/kg）在成年鸟和幼年鸟之间的浓度存在显著差异。我们研究中检测到的所有浓度均远低于意大利此前记录的普通雨燕体内的农药浓度以及已知会导致鸟类中毒和死亡的浓度。
