目的了解南宁市装修居室内空气污染状况对人体健康的影响,以提高人们防治意识。方法用气相色谱溶剂解析法检测苯、甲苯和二甲苯,纳氏试剂分光光度法测定氨,酚试剂比色法测定甲醛。结果 73户装修的室内空气污染监测中,甲苯超标率为9.6%,氨超标率为56.2%,甲醛超标率达47.9%,苯和二甲苯没有超标。结论南宁市居室装修室内空气污染物比较严重,应采取减少污染的防治措施。
[ Objective ] To understand the effect of indoor air pollution of decorated rooms on human health in Nanning City, im- prove people＇s consciousness of prevention and control. [ Methods ] The concentrations of benzene, toluene and xylene were detected by the gas chromatography solvent analytical method, the concentration of ammonia was tested by Nessler＇s reagent spectrophotome- ter, and the level of formaldehyde was determined by the phenol reagent colorimetric method. [ Results ] A total of 73 decorated households were monitored for the indoor air pollution. The over standard rate of toluene, ammonia and formaldehyde was 9.6%, 56.2% and 47.9%, respectively. The concentration of benzene and xylene met the standard.
