帐幕熏蒸中溴甲烷气体浓度变化规律及检测标准的研究

Studies on the concentration changing law of methyl bromide and detection criterion at curtain fumigation

采用科学的熏蒸剂检测方法，通过系统的浓度检测和分析，对口岸实际熏蒸中有代表性的３种地面条件熏蒸帐幕的气密性进行了比较，基本摸清了２５～３２℃温度条件下帐幕熏蒸中溴甲烷气体浓度的变化规律。结合试验研究结果，提出了可供熏蒸现场监管采用的浓度检测标准，并对帐幕熏蒸的部分技术性问题进行了探讨。

With scientific detection method, pharmacy concentrations were detected and analysed systematicly. Airtights of curtain fumigation among three representive ground conditions to practical fumigation work at ports were compared and known basically how the Methyl bromide changed in the curtain fumigation at 25 32℃. With the result of the test, detection standard of concentration was gained for supervising at fumigation scene, and some technical problems of curtain fumigation were probed.
