室内有机污染监测中甲醛与空气耗氧量的关系

The Relationship between Formaldehyde Content and the Level of Air Oxygen Consumption in Indoor Air

[目的 ]在监测室内有机污染时 ,分析甲醛与空气耗氧量的关系 ,寻找较合理的评价室内有机污染的指标。[方法 ]选择新装修三星宾馆、装修一年的二星宾馆和无装修的招待所 ,测定甲醛和空气耗氧量 ,同时监测新风量、微小气候等常规指标 ,以及能敏感反映人体早期损害的神经行为功能核心测试指标。 [结果 ]发现甲醛与空气耗氧量之间有线性回归关系 ,r =0 95 2 ,P <0 0 0 1;相对甲醛而言 ,空气耗氧量受室内微小气候影响较小 ,装修后衰减速度较快 ;计算接触者暴露量时 ,空气耗氧量指标与神经行为功能核心测试相关较密切。[结论 ]在监测室内有机污染时 ,甲醛是常用的指标 ,空气耗氧量可反映有机污染的总体水平 ,也可作为评价指标 。

Objective\]To study the relationship between formaldehyde (FD) content and the level of air oxygen consumption (AOC) in indoor air and to search a suitable evaluation index for air organic pollution \A three star hotel with newly decorated, a two star hotel with one year decoration and a popular hostel without decoration were selected in this surveillance The air formaldehyde content, level of air oxygen consumption, fresh air proportion and indoor microclimate were selected as the index of surveillance And nervous function of the attendants was tested by Neurobehavioral Core Test Battery (NCTB) \ The relationship between FD and AOC shown a linear regression function (r = 0 925, P<0 001) Comparing with FD, AOC was less influenced by indoor microclimate and declined quickly AOC was correlated significantly with the results of NCTB test \[Conclusion\]FD is a common index to monitor indoor air organic pollution, but the level of AOC can reflect the total level of organic compounds and can be used as an evaluation index
