An indoor air quality survey was conducted in Southern Louisiana to determine levels of airborne formaldehyde. Gas chromatography analyses of 419 air samples collected from 53 houses revealed levels of formaldehyde ranging from non-detectable to 6.60 mg/m3. Seventy four percent (312/419) of the samples had detectable amounts of airborne formaldehyde. Of the 312 positive samples, approximately 60% exceeded the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) guideline of 0.123 mg/m3. The highest number of samples exceeding the formaldehyde benchmark were collected in winter. It would appear that in some Southern Louisiana houses, a high level of formaldehyde could serve as a potential upper respiratory irritant.
在路易斯安那州南部进行了一项室内空气质量调查,以确定空气中甲醛的含量。对从53所房屋采集的419个空气样本进行气相色谱分析,结果显示甲醛含量范围为未检测到至6.60毫克/立方米。74%(312/419)的样本检测到空气中含有甲醛。在312个阳性样本中,约60%超过了美国供热、制冷与空调工程师协会(ASHRAE)0.123毫克/立方米的指导标准。超过甲醛基准的样本数量在冬季最多。看来在路易斯安那州南部的一些房屋中,高浓度的甲醛可能会对上呼吸道造成潜在刺激。
