In March 2017, 26 American goldfinches (Spinus tristis) were found dead following a drench application of imidacloprid in California (USA). Identical seed fragments were present in the digestive tracts. Imidacloprid was detected in 4 separate pooled samples from 18 birds, in crop/gizzard contents (4.8 ± 1.3 ppm; range 2.2-8.5 ppm) and liver tissues (3.9 ± 0.6 ppm; range 2.1-4.8 ppm). We suspect that fallen elm (Ulmus sp.) seeds were contaminated with imidacloprid during the drench application and subsequently ingested, resulting in acute toxicity and death.

2017 年 3 月,在美国加利福尼亚州,26 只金翅雀(Spinus tristis)在喷洒吡虫啉后死亡。在它们的消化道中发现了相同的种子碎片。在来自 18 只鸟类的 4 个单独混合样本中检测到吡虫啉,存在于嗉囊/肌胃内容物(4.8±1.3ppm;范围 2.2-8.5ppm)和肝脏组织(3.9±0.6ppm;范围 2.1-4.8ppm)中。我们怀疑在喷洒过程中,掉落的榆树(Ulmus sp.)种子被吡虫啉污染,随后被鸟类摄入,导致急性毒性和死亡。环境毒理化学 2019;38:1724-1727。©2019 作者。环境毒理化学由 Wiley 期刊出版公司代表 SETAC 出版。
