摘要
在2006—2007年冬、春两季,对东北地区典型室内42处9种有机挥发性污染物(VOCS)的污染状况进行了检测.其中苯和甲苯的检测点共38个.结果表明,苯冬季浓度超标点18个,超标率为47%;春季苯浓度超标点为6个,超标率为15.8%.甲苯冬季浓度超标点11个,超标率为28.95%;甲苯春季浓度超标点4个,超标率为10.5%.检测食堂4处,主要污染物是丙烯醛,丙烯醛的浓度和烹饪时间的长短有密切的关系,用餐高峰时段丙烯醛浓度是非高峰时段的2.6倍.研究表明,室内VOCS的浓度和环境温度、室内通风情况、室内装修状况及装修材料质量、学生用品类型密切相关.
Indoor air quality is very important for people health.This paper,studies 9 kinds VOCS in 42 typical rooms.9 kinds VOCS include benzene,toluene,m-xylene,o-xylene,ethylbenzene,butadiene,acetone,2-Methyl ethyl ketone,and 1,3,5-terimeth benzene.The rooms were classified two groups,the first group included dormitories,classrooms,offices,in this group 38 samples been detected.The second group is dining-room,4 samples been detected.In the first group 18 samples of benzene in winter,6 samples of benzene in spring are over standard,accounted for 47%,and 10.5% respectively in whole samples.The main VOCS in dining-room is acraldehyde.The concentration of cooking time is 2.6 times higher than no cooking time.To prevent VOCS influencing students and others health,the most important measurements are to avoid overdoing decoration and used green materials,and natural ventilation.The people should used the perfume with lower VOCS and with little smoking indoor.
