【摘要】：文中用酚试剂比色法对某学校内具有代表不同装饰程度教室的甲醛浓度进行了冬夏两季的监测与评价，结果表明：（1）无论冬季或夏季，A室与其它各教室比较，，差异都有高度显著性（P＜0．01），且A室夏季甲醛一次浓度超标率达33．3％，可见A定甲醛污染不容忽视。（2）各教室平均浓度变化范围，冬季为0．0126～0．0433mg／m3，夏季为0．0117～0．0949mg/m3，一次最高浓度可达0．1506mg/m3。（3）调查发现，室内装饰材料是教室内甲醛污染的主要来源，且甲醛浓度变化与室内温度及通风状况有关。
[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.

【正文快照】： 甲醛已证明是一种对人类具有潜在致癌性的环境污染物，随着现代化的建材、装饰和各种设备进入室内，甲醛作为一种新的室内污染物已引起人们的关注t’1，并且开始对非职业性环境的室内空气污染物（如甲醛）进行监测，但对学校教室内建筑的甲醛监测报道较少，为此，我们于1994
