装修材料中甲醛对室内空气污染的研究

目的:研究装修材料中甲醛对室内空气的污染情况。方法:采用变色酸比色法对24套新装修住宅和办公用房室内甲醛浓度进行测定,并分析门窗开与关及门窗关闭状况下橱门开与关情况甲醛浓度有无差异。结果:室内空气甲醛浓度是室外的6.56倍,为0.433mg/m3;住宅与办公用房室内甲醛浓度差别无显著性;门窗关的情况下室内甲醛浓度是开情况下的5.46倍,门窗关闭开橱门室内甲醛浓度是关橱门的1.79倍,在夏季朝北房间室内甲醛浓度较朝南的高,后3者均有显著性差异。结论:人工胶合板制作的家具是室内甲醛污染的主要来源,加强室内通风,常开门窗是降低甲醛污染的重要手段。

Study on indoor air contamination by formaldehyde in decorated material

Objective To study indoor air contamination. Methods Detecting the lever of formaldehyde(FM) in decorated apartment and workrooms.Result The indoor concentration of FM was 0.433mg/m3 and 6.56 times higher than outdoor.There was no significant difference in FM between apartments and workrooms, while significant difference between opening and closing window of room and doors of cabint. Conclusions The FM made of plywood is the main contamination souce of FM. Opening the windows frequently can reduce FM concentration of indoor air.
