非接触式人体气味检测实验研究

作为地震废墟环境下智能化搜索技术研究的基础，以非接触抽吸采样方式开展了模拟废墟空间内人体气味的检测实验研究。通过对若干人体呼气体、尿液、汗液挥发成份的分析，检测出了多种挥发性有机化合物，确定了异戊二烯、丙酮、甲基庚烯酮、柠檬油精等化合物可做为识别人体气味的主要标志，为研究地震废墟环境下基于人工嗅觉系统的寻人技术提供了重要依据。     

Determining indoor air quality and identifying the origin of odour episodes in indoor environments

A methodology for identifying volatile organic compounds (VOC) and determining air quality of indoor air has been developed. The air samples are collected using pump samplers by the inhabitants when they perceive odorous and/or discomfort episodes. Glass multi-sorbent tubes are connected to the pump samplers for the retention of VOC. The analysis is performed by automatic thermal desorption (ATD) coupled with gas chromatography-mass spectrometry (GC/MS). This methodology can be applied in cases of sick building syndrome (SBS) evaluation, in which building occupants experience a series of varied symptoms that appear to be linked to time spent in the building. Chemical pollutants concentrations (e.g., VOC) have been described to contribute to SBS. To exemplify the methodology, a qualitative determination and an evaluation of VOC present were performed in a dwelling where the occupants experienced the SBS symptoms. Higher total VOC (TVOC) value was detected in episodes in indoor air (1.33 ( 1.53 mg/m3) compared to outdoor air (0.71 ( 0.46 mg/m3). The concentrations of individual VOCs, such as ethanol, acetone, isopropanol, 1-butanol, acetic acid, acetonitrile and 1-metoxy-2-propanol, were also higher than the expected for a standard dwelling. The external source of VOC was found to be a not declared activity of storage and manipulation of solvents located at the bottom of a contiguous building.     

塞罕坝的气味

我曾到过很多草原,如内蒙古呼伦贝尔草原,新疆赛里木湖畔草原,河北省张（家口）北草原等等,但围场满族蒙古族自治县属的塞罕坝,是有别于许多草原和森林地区的天然公园。它在地貌和植被分布上,有山地、有森林,有丘陵、有草原,既有河流、又有湖泊。有识者赞誉为“河的源头,云的故乡,花的世界,林的海洋,珍禽异兽的天堂”。

汽车四种非金属零部件气味提升建议

消费者关于汽车车内空气质量的投诉越来越多,汽车车内空气质量的的改善已经成为各主机厂的重点项目.车内空气质量主要包括车内挥发性有机物、客户感知的车内气味物质.随着各大主机厂的管控技术及流程日益成熟,挥发性有机物已能满足GB/T 27630-2011的限值要求,而气味因无设备检测,构成复杂往往难以有效管控.本文是针对四种车...     

汽车备胎盖板材料的VOC溯源研究

本文对备胎盖板及各组份材料进行气味性测试,同时结合热脱附气相色谱质谱联用仪(TD-GCMS)测定各组分的挥发性有机物(VOC),找出备胎盖板的气味来源及关键性气味物质.结果发现喷胶面料是直接影响总成气味的材料组份,同时找出了引起异味的关键气味物质为甲基丙烯酸丁酯、甲基丙烯酸甲酯、四甲基丁二腈、甲基吡咯烷酮、乙醛,这些物...
