This paper reports on a fatal intoxication by oral ingestion of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). At admission, the victim was unconscious. His condition deteroriated rapidly with blood loss from his mouth and nose. Since the cause of this condition was not known, gastroscopy was performed and haemorrhagic mucosa was observed in the mouth, oesophagus and stomach. Gastric contents (removed by lavage), urine and blood were submitted for toxicological analysis. Unfortunately, within 3 h of admission (about 5 h following ingestion of the toxin) profound cardiogenic shock developed and the patient died. The identity of the toxic xenobiotic was revealed by gas chromatography-mass spectrometry. Analytical quantification of the herbicide was performed by acid extraction prior to gas chromatographic examination using electron capture detection. His blood level of 2,4-D was 192 mg l-1.
本文报道了一起因口服除草剂2,4-二氯苯氧乙酸(2,4-D)导致的致命中毒事件。入院时,受害者已失去意识。他的病情迅速恶化,口鼻出血。由于病因不明,遂进行了胃镜检查,发现口腔、食管和胃内有出血性黏膜。采集了胃内容物(洗胃所得)、尿液和血液进行毒理学分析。不幸的是,入院后3小时内(摄入毒素约5小时后),患者出现严重的心源性休克并死亡。通过气相色谱-质谱联用仪确定了有毒外源性物质的身份。在使用电子捕获检测进行气相色谱检查之前,通过酸萃取对除草剂进行了分析定量。他血液中的2,4-D含量为192毫克/升。
