【摘要】：目的了解成都市新装修室内环境空气中氨污染的状况并探讨防治措施。方法对成都市50多处企事业单位与住宅小区的办公室、居室、公共场所室内空气中的氨进行了调查采样,选取其中具有代表性的12个采样点的监测结果进行分析。将装修费用和复杂程度相近的采样点按装修后不同时间(装修后0.5、1、2、3、4、5个月)分成6组,每组3～5个采样点,分别测定空气中氨的浓度。结果有代表性的12个采样点的空气中氨的平均浓度为0.307mg/m3,最高浓度为0.598mg/m3,接近国家标准的3倍,氨浓度的超标率为58.33%。装修程度相似的室内环境装修后不同时间空气中氨的平均浓度随时间的推移呈下降趋势,一般到装修后4个月时就可以达到标准值(0.20mg/m3)。结论新装修室内环境空气中存在一定程度的氨污染,房屋装修后保持有效通风5个月再入住为宜。
[Abstract]:Objective to investigate the ammonia pollution in the newly decorated indoor air in Chengdu. Methods the ammonia in the indoor air of more than 50 enterprises and residential areas in Chengdu were investigated and sampled, and the monitoring results of 12 representative sampling sites were analyzed. The sampling points with similar decoration cost and complexity were divided into 6 groups according to different time after decoration (0.5 ~ 5). The concentration of ammonia in the air was determined by 3 ~ 5 sampling points in each group. Results the average concentration of ammonia in the air of 12 representative sampling sites was 0.307 mg / m ~ (3), the highest concentration was 0.598 mg / m ~ (3), which was nearly 3 times of the national standard, and the rate of exceeding the standard of ammonia concentration was 58.33%. The average concentration of ammonia in the indoor environment with the same degree of decoration showed a decreasing trend with the passage of time, and generally reached the standard value (0.20mg/m3) 4 months after decoration. Conclusion A certain degree of ammonia pollution exists in the air of the newly decorated indoor environment, and it is appropriate to keep effective ventilation for 5 months after the house decoration.
