新装修居室空气甲醛浓度的调查

目的：为了解新装修住宅室内空气甲醛污染状况。方法：在长沙市城区东、南、西、北随机抽取17户新装修、添置了新的木制家具的居室内设点监测。结果：62．5％的监测点空气中甲醛浓度超过标准，最高浓度为2．2m8／m：，超标27．5倍，装修三个月内的居室空气中甲醛浓度及超标率均显著高于装修三个月后居室空气中甲醛浓度及超标率。结论：居室装修对室内空气的污染不容忽视．室内空气甲醛浓度随着时间的延长而逐步降低。建议采取多项综合措施．减少室内污染物的浓度。

An Investigation of Formaldehyde Concentration in New Decorated Rooms

Objective To explore the formaldehyde concentration in new decorated rooms. Methods 17 sampling rooms from northern?southern?eastern and western parts of Changsha city were measurod.
