室内装修污染对人体健康的危害及防治对策 总被引:1,自引:0,他引:1
随着生活水平的提高,人们对居住环境的质量要求也越越高。家庭住宅室内装修虽然在感官和视觉上满足了人们求,但同时带来室内空气污染问题,对人体健康造成严重的害。装修后室内存在的主要污染物及危害.1甲醛(HCHO):常温下为气体,有强烈刺激性气味,易溶水。甲醛是生产树脂(如脲醛树脂、酚醛树脂等)的重要原,这些树脂主要用作粘合剂。各种人造板材(如纤维板、胶合等)由于使用了粘合剂而含有甲醛。甲醛的室内来源较多,染浓度也较高,是装修后室内首要污染物。室内甲醛主要来自装修中使用的各种板材、涂料、板材包括地板)表面使用的油漆和在墙壁装饰色彩鲜艳的壁纸,这些装饰材料中不同程度地含有甲醛。购买的新家具,也甲醛室内污染来源的一个方面。甲醛对室内暴露者的健康影响主要是嗅到异味、刺激眼呼吸道粘膜产生变态反应、免疫功能异常,损伤肝、肺和中神经系统,还可损伤细胞内的遗传物质。主要可分为急性中、慢性危害、远期影响。急性中毒:主要是对暴露部位(眼、皮肤)和呼吸道粘膜的激。人的甲醛嗅觉阈为0.06—0.07mg/m3,0.15mg/m3就可起眼红、眼痒、流泪、咽喉干燥发痒、咳嗽、气喘、声音嘶哑、闷、皮肤干燥发痒、皮炎等。慢性危害:主要是可引起变态... 相似文献

在大型(30m3)、小型(1m3)环境箱实验获得数据的基础上构建释放模型,并将模拟结果和现场监测得到的浓度水平进行对比,对开发的室内空气污染预测方法进行了实证研究.以一新装修房间为例,分别利用大型和小型环境箱实验,研究了复杂整装材料和简单层状材料的释放规律,建立了相应材料的污染物释放模型;依据单元内物质守恒理论和污染物充分混合的假设将释放模型组合,建立了室内空气污染预测方法,并预测了该房间甲醛和TVOC(total volatile organic compounds)浓度的变化过程.在考虑了0.03ACH(air change per hour)的换气率之后,模型预测与现场监测的污染物浓度变化趋势基本吻合,甲醛和TVOC污染预测误差(正则化标准差)分别为2.8%和1.6%.模型分析表明,各污染源对于甲醛污染的贡献,家具>涂料>地板;对于TVOC污染的贡献,涂料>地板>家具.结论表明,该预测方法可以真实反映现场污染物浓度变化趋势,可以用来分析各污染源对于整体污染的贡献、指导装修材料的选择和作为室内污染评估和控制的有效工具. 相似文献

The nuisance from odor caused by municipal solid waste(MSW) is resulting in a growing number of public complaints and concerns. Odor pollution occurs in the initial decomposition stage of MSW, including waste collection, transportation and early pre-treatment. Furthermore, decomposition takes place in waste facilities that are often close to living areas, which can result in odor impacts on local inhabitants. However, this aspect of odor impact from MSW has not been well studied. In the current ... 相似文献

我国餐厨废物生化处理设施恶臭排放特征分析 总被引:4,自引:1,他引:3
选择目前国内餐厨废物成功进行资源化处理的代表性城市西宁、北京和宁波,分别对其处理处置情况进行调研并设置采样点,采用气相色谱-质谱联用(GC/MS)对各企业主要恶臭排放工段的恶臭物质进行定性定量分析,采用三点比较式臭袋法对各企业主要恶臭排放工段的臭气浓度进行测试分析.结果表明,餐厨垃圾生化处理企业的排放物质种类主要为醇、醛、酮、酯的含氧烃类,但对恶臭贡献最大的是含硫化合物,其次是萜烯类物质;综合西宁、宁波和北京的调研及分析结果,可初步考虑餐厨垃圾生化处理设施典型恶臭物质为乙醇、柠檬烯、硫化氢、甲硫醇、甲硫醚、二甲二硫醚、乙醛、乙酸乙酯. 相似文献

建材行业是典型的资源和能源消耗型产业,也是大气污染的主要排放源之一.中国作为全球最大的建材产品生产国和消费国,目前针对建材行业排放特征的研究总体较少,数据来源较为单一.以河南省建材行业为研究对象,首次将应急减排清单应用到排放清单构建中,通过对应急减排清单、排污许可和环境统计等多源数据的融合研究,完善和细化了建材行业活动水平数据,建立了更为精准的河南省建材行业排放清单.结果表明,2020年河南省建材行业的SO2、 NOx、一次PM2.5和PM10的排放量分别为21 788、 51 427、 10 107和14 471 t.其中,水泥和砖瓦是河南省建材行业大气污染物排放占比最高的2个行业,合计超过50%,水泥行业NOx排放问题较为突出,砖瓦行业整体治理水平比较落后.豫中和豫北是河南省建材行业排放贡献最高的地区,合计超过全省的60%.建议加快推进水泥行业超低排放改造,针对砖瓦等行业完善地方排放标准,持续提升建材行业大气污染治理水平. 相似文献

This study investigates the global impact of wood as a building material by considering emissions of carbon dioxide to the atmosphere. Wood is compared with other materials in terms of stored carbon and emissions of carbon dioxide from fossil fuel energy used in manufacturing. An analysis of typical forms of building construction shows that wood buildings require much lower process energy and result in lower carbon emissions than buildings of other materials such as brick, aluminium, steel and concrete. If a shift is made towards greater use of wood in buildings, the low fossil fuel requirement for manufacturing wood compared with other materials is much more significant in the long term than the carbon stored in the wood building products.As a corollary, a shift from wood to non-wood materials would result in an increase in energy requirements and carbon emissions.The results presented in this paper show that a 17% increase in wood usage in the New Zealand building industry could result in a 20% reduction in carbon emissions from the manufacture of all building materials, being a reduction of about 1.5% of New Zealand’s total emissions. The reduction in emissions is mainly a result of using wood in place of brick and aluminium, and to a lesser extent steel and concrete, all of which require much more process energy than wood. There would be a corresponding decrease of about 1.5% in total national fossil fuel consumption. These figures have implications for the global forestry and building industries. Any increases in wood use must be accompanied by corresponding increases in areas of forest being managed for long term sustained yield production. 相似文献

Odorous compounds in the influent of a reclaimed water treatment plant (RWTP), consisting of coagulation, sedimentation, continuous micro-filtration (CMF), and chlorination in succession, in a north China city, were identified by combining flavor profile analysis (FPA) with sensory gas chromatograph-mass spectrometry (GC-MS). The sewery/swampy/septic odor with an odor intensity of 6.4 was found to be the major odor group in the RWTP influent, and the existence of well-known odorant including dimethyl disulfide, dimethyl trisulfide, indole and skatole were confirmed using GC-MS. The result of a spiking test showed that the intensity (3.6) of the sewery/swampy/septic odor caused by these four chemicals contributed to over 50% of the odor intensity of the influent. The FPA intensity for sewery/swampy/septic odor in the RWTP effluent was 3.8, showing that the treatment process was not efficient for the removal of odorants, particularly indole and skatole. 相似文献

Source separation sanitation systems have attracted more and more attention recently.However, separate urine collection and treatment could induce odor issues, especially in large scale application. In order to avoid such issues, it is necessary to monitor the odor related compounds that might be generated during urine storage. This study investigated the odorous compounds that emitted from source-separated human urine under different hydrolysis conditions. Batch experiments were conducted to investigate the effect of temperature, stale/fresh urine ratio and urine dilution on odor emissions. It was found that ammonia, dimethyl disulfide, allyl methyl sulfide and 4-heptanone were the main odorous compounds generated from human urine, with headspace concentrations hundreds of times higher than their respective odor thresholds. Furthermore, the high temperature accelerated urine hydrolysis and liquid–gas mass transfer, resulting a remarkable increase of odor emissions from the urine solution. The addition of stale urine enhanced urine hydrolysis and expedited odor emissions. On the contrary, diluted urine emitted less odorous compounds ascribed to reduced concentrations of odorant precursors. In addition,this study quantified the odor emissions and revealed the constraints of urine source separation in real-world applications. To address the odor issue, several control strategies are recommended for odor mitigation or elimination from an engineering perspective. 相似文献
