Monitoring of total volatile organic compounds and particulate matter in an indoor environment

摘要

Indoor air pollution in the workplace is considered as one of the most potential environment risks to an occupant's health. Office employees are exposed to airborne pollutants that include particulate matter (PM), volatile organic compounds (VOCs), gases chemicals and microorganisms originating from indoor and ourdoor sources. Exposure to PM and VOCs is likely to be higher in the workplace than outdoors due to the amount of time people spend in the indoor environment. A weekly monitoring of VOCs and PM with sampling period of 8 h was carried out in an indoor (office) environment in order to evaluate the exposure to pollutant concentration. The sampling was carried out with the help of a Grimm dust monitor and potable VOC monitor for PM and VOCs respectively. The results clearly show that exposure to PM and VOCs is much higher in an office building.
