摘　　要：在熏蒸库房使用溴甲烷(56 g/m^3)熏蒸处理木质包装,监测不同时间和高度的溴甲烷浓度。结果表明,熏蒸处理期间随时间的推移,溴甲烷浓度逐步降低;在各检测时间溴甲烷浓度平均值表现为高度越高浓度越低的现象;相差0.8 m高的溴甲烷浓度平均值相差1.37～2.19 g/m^3;相差1.6 m高的溴甲烷浓度平均值相差2.86～4.08 g/m^3,差异十分显著(SSR_(0.01))。Wooden packing was fumigation processed by methyl bromide （56 g/m^3）, concentration of methyl bromide at different heights and times were monitored. The results showed that concentration of methyl bromide decreased as fumigation time prolonged. Analysis on the average concentration of methyl bromide at different testing times showed that the concentration decline was slower when the height was higher. The average concentration of methyl bromide changed from 1.37 to 2.19 g/m^3 when the height difference was 0.8 m, and which changed from 2.86 to 4.08 g/m^3 when the height difference, was 1.6 m, and the difference was extremely significant （SSR0.01）.
