新装修居室甲醛监测技术规范的探讨

DISCUSSION ON SPECIFICATIONS OF MONITORING TECHNOLOGY ON FORMALDEHYDE IN NEWLY DECORATED ROOM

[目的]为了解关闭门窗不同时间及是否打开柜门对甲醛监测结果的影响,以及进一步完善《室内空气监测技术》。[方法]选择市区20家新装修的居室进行调查监测。[结果]采样点高度并不影响室内空气质量检测结果;门窗关闭不同时间后甲醛含量有差异,关闭门窗后3 h内,是室内空气中污染物(甲醛浓度)的散发快速期;监测时房间家具柜门打开与关闭对甲醛监测结果是有明显影响,但关闭门窗3 h后检测,对室内甲醛的达标率差异无统计学意义。[结论]为了保护人体健康、预防和控制室内空气污染的目的,建议采用关闭对外门窗3 h后进行检测。

[Objective] In order to understand the influences on the monitoring results of formaldehyde when closing doors and windows in different time and whether to open doors and to improve the Indoor Air Quality Monitoring Teehnology. [Methods] 20 urban residences neMy decorated were monitored and surveyed. [ Results] The heights of sampling point did not affect the metered quality of indoor air. The contents of formaldehyde were different when closing doors and windows in different time. Within 3 hours after the doors and windows closed, poilutants in air （formaldehyde） disseminated rapidly, the monitoring results of formaldehyde were obviously different between the door opened and closed. After 3 hours when the doors and windows closed, the qualified rate of indoor formaldehyde had no significant difference. [Conclusion] In order to l）rotect persons＇ health and control the pollution of indoor air. extemal doors and windows should be closed three hours before detecting.
