摘要
目的 ]了解装修后办公室内空气污染状况。 [方法 ]对一间装修后使用不到半年的面积 >10 0 0 m2 的封闭式现代化办公室进行空气采样。 [结果 ]除可吸入尘 (0 .0 6～ 0 .0 7mg/ m3)外 ,甲醛 (0 .85～ 0 .96 mg/ m3)、氨(1.6 5～ 3.35 mg/ m3)、耗氧量 (9.2 0～ 9.30 mg/ m3)、苯 (0 .42～ 0 .5 6 mg/ m3)、甲苯 (0 .5 8～ 0 .91mg/ m3)、乙苯(0 .10～ 0 .12 mg/ m3)、二甲苯 (0 .10～ 0 .12 mg/ m3)、二氧化碳 (0 .13%～ 0 .16 % )和细菌总数 (2 10 0～ 5 0 0 0 CFU/m3)均超过相关标准 1～ 10倍。 [结论 ]该办公室空气污染较严重 。
Objective]To understand the indoor air pollution of decorated office [Methods]Indoor air sampling was carried out in a closed modern office with an area of more than 1 000 m 2,which had been used for less than half a year after decoration [Results]Except the levels of inhalable particulates(0 06~0 07 mg/m 3),the levels of other 9 indexes,such as formaldehyde(0 85~0 96 mg/m 3),ammonia(1 65~3 35 mg/m 3),COD(9 20~9 30 mg/m 3) benzene(0 42~0 56 mg/m 3),methylbenzene(0 58~0 91 mg/m 3),ethylbenzene(0 10~0 12 mg/m 3),dimethylbenzene(0 10~0 12 mg/m 3),CO 2(0 13%~0 16%)and the total count of bacteria(2 100~5 000 CFU/m 3),exceeded the relative national sanitary standard 1~10 times respectively [Conclusion]In the observed decorated office indoor,air was highly polluted Increasing the indoor ventilation and the application of air purification devices should be adopted to improve the sanitary quality of indoor air
