奥运场馆室内空气品质测评   总被引:2,自引:0,他引:2  
为保证奥运场馆的室内空气品质满足人们的健康要求和舒适感觉,本文对北京奥运篮球馆、水上公园及奥运媒体村的室内空气品质进行了赛前检测,并以甲醛、苯、甲苯、二甲苯、TVOC、氨6种化学性污染物作为评价指标,在对室内空气进行单因子指标分析的前提下结合空气品质综合指数法对检测场馆的室内空气品质进行了客观评价.结果表明:检测场馆室内空气单项污染指标超标率低,空气评价等级为清洁和未污染的检测点位占到了95%以上.对超标污染物,通过自然通风措施即可确保达标.  相似文献

随着城市经济发展,室内空气污染问题引起了人们的广泛关注,但人对于室内空气品质的感受是模糊的,不能单纯地仅依靠数据进行客观评价,而模糊评价法以其特性,使得这种评价成为可能。基此,立足室内空气品质的定义、国内污染源的特征、室内空气品质对人的影响、污染源暴露水平和健康风险等方面,引入模糊数学理论对室内空气品质进行模糊综合性评价。评价结果表明,利用模糊数学理论能够更全面、更准确地反映室内空气的污染程度。  相似文献

室内空气品质预测属于主观判断,预测结果的准确性取决于评价方法的可靠性、预测模型的合理性、预测条件与实际条件的吻合程度等因素。文章分析了常用的室内空气品质预测方法中存在的问题,根据室内空气品质不满意率和化学污染物对数评价指标间的线性关系,在室内污染物浓度场预测的基础上提出了一种预测室内空气品质的新方法。  相似文献

为了了解广州市公共建筑客房的室内空气品质状况,本文对不同类型客房的室内空气进行了检测,并采用SPSS12.0软件对数据进行了分析,同时用空气质量综合指数法对其进行了综合评价。结果表明:客房内物理性参数大部分在合格范围内,冬季室内物理性参数超标率较大,对于各房间,风速分布差异显著;客房内的空气属于未污染,各参数实测的平均浓度均在室内空气质量标准的规定范围内,各参数的指数在0.27~0.63之间,超标率较低;对于不同的房间,室内的CO、CO2、PM10的实测浓度与指数分布无显著性差异(P实测=0.014~0.516〉0.01,P指数=0.060~0.601〉0.01),而甲醛和细菌总数的实测浓度与指数分布差异显著。  相似文献

This paper reviews the published literature on indoor thermal environment and air quality in Chinese-style residential kitchens (CRKs). The paper first discusses typical characteristics of CRKs, including kitchen layout, cooking methods, and ventilation systems used. Next, the paper describes the current state of the indoor thermal environment and air quality in CRKs. Finally, this paper summarizes measures to control and improve the environment inside CRKs. The results indicate that the indoor environment of CRKs is too hot in summer and exhibits a large vertical temperature difference. No appropriate model was available for accurately evaluating the thermal environment in CRKs. At the same time, CRKs are highly polluted by COx, NOx, TVOC, and particulate matter (PM). Although existing exhaust hoods could improve the indoor environment to some extent, the use of a combined exhaust, make-up air, and air-conditioning system should be considered to provide a comfortable and healthy environment in CRKs.  相似文献

To improve indoor air quality and to protect public health, Taiwan has enacted the “Indoor Air Quality Act (IAQ Act)” in 2012. For the general public, the indoor air quality in hair salons is important because it is a popular location that people will often visit for hair treatments. However, only a few exposure assessments regarding air pollutants have previously been performed in hair salons. To assess the air quality of hairdressing environments in Taipei, ten hairdressing salons were included for a walk‐through survey in this study. In addition, the airborne concentrations of formaldehyde, volatile organic compounds (VOCs), CO2, and phthalate esters were also determined in 5 salons. Charcoal, XAD‐2, and OVS‐Tenax tubes were used for the air sampling, while the samples were analyzed with gas chromatography/mass spectrometer. It was found that the products used in hair salons contained various chemicals. In fact, from the walk‐through survey, a total of 387 different ingredients were found on 129 hair product labels. The hair salons were not well ventilated, with CO2 levels of 600 to 3576 ppm. The formaldehyde concentrations determined in this study ranged from 12.40 to 1.04 × 103 μg m?3, and the maximum level was above the permissible exposure limit (PEL) of US Occupational Safety and Health Administration (US OSHA). Additionally, 83% of the samples were with levels higher than the standard regulated by Taiwan's IAQ Act. The concentrations of VOCs and phthalate esters were below the occupational exposure limits (OELs), but higher than what was found in general residential environments. The hair products were considered as the major source of air pollutants because significantly higher concentrations were found around the working areas. The number of perming treatments, the number of workers, and the frequency of using formaldehyde releasing products, were found to be associated with the levels of formaldehyde. This study indicates that efforts are needed to improve the indoor air quality in hairdressing salons in Taipei.  相似文献
