某市一商业银行营业网点空气质量检测结果分析

目的了解新旧银行营业网点办公区内空气质量的状况。方法甲醛采用MODELHE-102型甲醛测定仪现场测定,苯、甲苯、二甲苯采用SQC-1000型大气采样器活性炭管采样,Agilent Technologies 6890N气象色谱仪FID检测器测定,新风量采用Telaire-7001型红外二氧化碳、新风量测定仪测定。结果对16处营业中的营业网点及11处新装修的营业网点空气质量进行检测,旧营业网点的不符合项为新风量,合格率为18.2%。新营业网点不符合项为污染物,甲醛超标率最高,点超标率为38.8%,最高浓度为0.665mg/m3,最高点超标6.7倍;苯、甲苯、二甲苯点超标率分别为9.6%、22.3%、15.2%,最高浓度分别为0.260mg/m3、0.840mg/m3、0.620mg/m3,最高点超标分别为2.6倍、4.2倍、3.1倍。结论旧营业网点新风量不达标,主要原因为抽风换气不足;新营业网点通风换气比较好,但存在装修污染物超标,其中甲醛是主要污染物,其次为苯系物,装修材料中木材、油漆、涂料、办公家具是造成污染的主要原因。

Analysis on indoor air quality testing results of a commercial bank outlets

Objective To study the new and old bank outlets office indoor air quality condition.Methods Formaldehyde were measured by MODEL HE-102-type formaldehyde detector.Benzene,toluene,xylene were collected by carbon air sampling tube and detected by Agilent Technologies 6890N gas chromatograph FID detection.Fresh air volume were detected by Telaire-7001 type infrared carbon dioxide and fresh air volume measuring device.Results The air quality of 16 business outlets and 11 new business outlets were detected.The old business outlets did not accord with fresh air volume,the qualified rate was 18.2%.The new business outlets did not accord with pollutants exceed standard.The highest exceed rate of pollutant exceed standard was formaldehyde,the point exceed rate was 38.8%,the highest concentration was 0.665 mg/m 3,the highest point exceed 6.7 times.Benzene,toluene,xylene point exceed rate was respectively 9.6%,22.3%,15.2%,the highest concentrations was respectively 0.260 mg/m 3,0.840 mg/m 3,0.620 mg/m 3,the highest point exceed respectively 2.6 times,4.2 times,3.1times.Conclusion The fresh air volume of old business outlets were under standard,the main reason for lack of ventilation.The ventilation of new business outlets were better,but the presence of decoration pollutants exceed standard,in which formaldehyde was one of main pollutants,followed by benzene.Decoration materials,wood,paint,coating,off ice furniture were the major reason of causing pollution.
