闭合式蚊香盘的实验研究

Laboratory Research for Closure Type Mosquito Coil Incense Utensil

目的 :降低盘式蚊香使用过程中产生的挥发性有害物质和尘埃粒子数量 ,减少室内空气污染 ,提高生活环境质量 ,保障人体健康。方法 :通过测定燃烧过程中释放出污染物质的吸附率、空气中尘埃粒子数和对生物药效的影响等 ,对闭合式蚊香盘与常规使用的敞开式蚊香盘进行对照观察。结果 :闭合式新蚊香盘与对照组的效果无明显差异 ;挥发性物质过滤吸收率达到 6 7.49% (u =9.42 ,P <0 .0 5 ) ;两组在燃烧过程中产生≥ 0 .5 μm尘埃粒子数 ,平均增量分别为 6 7771.75和 71811.84个 /L ,比对照组减少 5 .6 3 % ( χ2 =40 .77,P <0 .0 5 ) ;尘埃粒子数随着点燃时间的延长而减少 (r =0 .9888,t=11.47,P <0 .0 5 ) ;模拟现场生物药效测试 ,1h击倒率分别为 32 %和 2 8% ,3h均为 10 0 %。结论 :闭合式蚊香盘可降低 6 7.49%的污染物质、5 .6 3%≥ 0 .5 μm的尘埃粒子数 。

Objective:To research for closure type mosquito coil incense utensil. Methods:To detect the dust, incense utensil and volatile noxious. Results:This paper reported that both the closure type and the opening type mosquito coil incense utensil. The volatile noxious to be one's health of the matter, decrease 67.49 %, u = 9.42 , P < 0.05 ;≥ 0.5 μm dust 67 771.75 /L and 71 811.84 /L, decrease 5.63 %,χ 2 = 40.77 , P < 0.05 ;≥ 0.5 μm dust as time going on was decrease, r = 0.988 8 , t = 11.47 , P < 0.05 ;simulation locale test results of the biometrics , unconsciousness rate : 1 hour 32% and 28%, 3 hour both the closure type and the opening type mosquito coil incense utensil 100%.
