Fumigation is required as an appropriate biosecurity measure to exterminate insect pests in shipping containers. The aim of this study was to determine if ethyl formate (EF) + nitrogen could be safely applied as an in-transit fumigant for containers transported on land and then by sea. In-transit fumigation trials were conducted in four 20 ft shipping containers during a four-day journey in December 2019 in Western Australia. Ethyl formate (90 g m) was released with nitrogen into the containers. Ethyl formate concentrations inside the containers and the surrounding environment on the barge were monitored at timed intervals throughout the overnight voyage. This study added new data on in-transit fumigation with ethyl formate + nitrogen via road and has successfully demonstrated safety of in-transit fumigation with ethyl formate + nitrogen via the marine sector. There was no detectable risk to the public, crew members on the barge or workers throughout the journey. In addition, all tested containers were ready to be opened and unloaded with 5-10 minutes aeration or without aeration upon arrival.
熏蒸是一种适当的生物安全措施，用于消灭运输集装箱中的害虫。本研究的目的是确定乙基甲酸酯 (EF) + 氮气是否可以安全地用作在陆地和海上运输的集装箱的运输中熏蒸剂。在 2019 年 12 月澳大利亚西部的为期四天的旅程中，在四个 20 英尺的集装箱中进行了运输中熏蒸试验。将乙基甲酸酯（90g m）与氮气一起释放到容器中。在整个夜间航行过程中，定时监测容器内部和驳船上周围环境中的乙基甲酸酯浓度。本研究通过公路增加了乙基甲酸酯+氮气运输中熏蒸的新数据，并成功证明了乙基甲酸酯+氮气通过海洋部门运输中熏蒸的安全性。在整个旅程中，公众、驳船上的船员或工人都没有察觉到风险。此外，所有经过测试的集装箱在到达后只需通风 5-10 分钟或无需通风即可打开和卸下。
