Investigation on Indoor Air Pollution of Office

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
