Endosulfan, a highly toxic insecticide and acaricide, was globally banned under the Stockholm Convention in May 2011 because of its threats to human health and the environment. Despite the ban on its use, endosulfan is still present in the environment, causing poisoning events in domestic animals and wildlife. Toxicologic analysis of poisoned animals conducted by the Istituto Zooprofilattico Sperimentale del Mezzogiorno revealed that in the past 3 y, this pesticide has not disappeared in the regions of interest. More than 650 samples (baits and animal organs) collected from 2013 to 2015 were analyzed through solid-phase extraction followed by gas chromatography-electron capture detection. This methodology allowed us to identify 45 positive samples from the Calabria region of southern Italy (10.2 % of the total samples). Most were samples of gastric content (alpha-endosulfan range: 1.27-3,800 mg/kg) and baits (alpha-endosulfan range: 92-1,497 mg/kg). Lower concentrations of pesticide were found in samples of stomach (alpha-endosulfan: 6.7-118 mg/kg) and liver (alpha-endosulfan: 0.38-14.2 mg/kg).
硫丹是一种剧毒杀虫剂和杀螨剂，由于其对人类健康和环境构成威胁，于2011年5月被《斯德哥尔摩公约》全球禁用。尽管已禁止使用硫丹，但它仍存在于环境中，导致家畜和野生动物中毒事件。意大利南部动物卫生实验研究所对中毒动物进行的毒理学分析表明，在过去3年里，这种农药在相关地区并未消失。对2013年至2015年收集的650多个样本（诱饵和动物器官）通过固相萃取，然后进行气相色谱 - 电子捕获检测进行了分析。这种方法使我们能够从意大利南部的卡拉布里亚地区识别出45个阳性样本（占总样本的10.2%）。大多数是胃内容物样本（α - 硫丹含量范围：1.27 - 3800毫克/千克）和诱饵样本（α - 硫丹含量范围：92 - 1497毫克/千克）。在胃样本（α - 硫丹：6.7 - 118毫克/千克）和肝脏样本（α - 硫丹：0.38 - 14.2毫克/千克）中发现了较低浓度的农药。
