【摘要】：文中用酚試劑比色法對某學(xué)校內(nèi)具有代表不同裝飾程度教室的甲醛濃度進行了冬夏兩季的監(jiān)測與評價，結(jié)果表明：（1）無論冬季或夏季，A室與其它各教室比較，，差異都有高度顯著性（P＜0．01），且A室夏季甲醛一次濃度超標(biāo)率達33．3％，可見A定甲醛污染不容忽視。（2）各教室平均濃度變化范圍，冬季為0．0126～0．0433mg／m3，夏季為0．0117～0．0949mg/m3，一次最高濃度可達0．1506mg/m3。（3）調(diào)查發(fā)現(xiàn)，室內(nèi)裝飾材料是教室內(nèi)甲醛污染的主要來源，且甲醛濃度變化與室內(nèi)溫度及通風(fēng)狀況有關(guān)。
[Abstract]:In this paper, phenol reagent colorimetry was used to monitor and evaluate the formaldehyde concentration in the classrooms with different decoration degrees in a school. The results showed that the concentration of formaldehyde in winter or summer was determined by using the method of phenol reagent colorimetry. Compared with other classrooms, there was a significant difference between room A and other classrooms (P < 0.01), and the rate of over standard formaldehyde concentration in room A in summer was 33.3%. It can be seen that A determination of formaldehyde pollution can not be ignored.) the average concentration range of each classroom is 0.0126 ~ 0.0433 mg / m ~ 3 in winter. The results showed that the indoor decoration material was the main source of formaldehyde pollution in the classroom, with a maximum concentration of 0.1506 mg / m ~ 3 路m ~ 3 路m ~ (3 / 3) in summer, which was 0.0117 mg / m ~ (3) and 0.0949 mg / m ~ (3) in summer. The change of formaldehyde concentration is related to indoor temperature and ventilation.
