【摘要】：目的研究裝潢后辦公室內空氣中甲醛含量的變化趨勢。方法選定7間同時裝潢了3個月后的辦公室 ,每隔1.5個月監(jiān)測1次室內空氣中甲醛濃度 ,同時測室溫 ,連續(xù)監(jiān)測5次。結果裝潢3個月后至10個月 ,室溫從14℃降到10℃ ,后又回升到26℃ ;室內甲醛平均濃度從0 22mg/m3 下降到0 09mg/m3 后又回升到0 22mg/m3;超標率從57 1%下降到0,又回升到85.7 %。結論監(jiān)測期間 ,辦公室內空氣中甲醛含量未隨裝潢后時間延長而降低 ,而是隨著室溫的改變而發(fā)生相應變化 ,且有些室內空氣中甲醛含量明顯超過國家衛(wèi)生標準。
[Abstract]:Objective to study the change trend of formaldehyde content in office air after decoration. Methods 7 offices which had been decorated simultaneously for 3 months were selected. Formaldehyde concentration in indoor air was monitored once every 1.5 months, and room temperature was measured at the same time for 5 consecutive times. Results after 3 months to 10 months of decoration, the room temperature decreased from 14 鈩，
