摘要
城市中家居市场集聚区域由于家具陈列与仓储,是城市挥发性有机物(Volatile organic compounds,VOCs)无组织排放主要贡献源之一。对济南市区内家居市场及周边环境空气VOCs进行现场监测,分析了不同类型家居市场VOCs排放特征和成分谱,计算不同类型家居市场VOCs排放因子及排放量,并与周围环境空气中VOCs组分特征进行对比。结果表明,济南市低档家居市场D中VOCs质量浓度最高为653.00μg·m^(-3),其次为中档家居市场C和B,高档家居市场A内VOCs质量浓度最低,为149.00μg·m-3;市场内VOCs主要种类为OVOCs、芳香烃和卤代烃,低档家居市场D中芳香烃占比最高(39.05%),其他家居市场OVOCs占比最高;各家居市场臭氧生成潜势OFP从大到小依次为D>B>C>A,芳香烃OFP在家居市场占比最大;不同档次家居市场中VOCs组分种类有差异,低档家居市场VOCs组分种类最多,各家居市场均检出丙酮、甲苯和邻二甲苯,主要是受市场内胶合板类家具释放的影响,低档家居市场D中二氯甲烷质量浓度最高,为183.00μg·m^(-3),中高档家居市场丙酮质量浓度均最高,为188.00μg·m^(-3),与市场内实木家具和水溶性涂料的家具释放有关;对比家居市场与环境空气VOCs组分发现,家居市场和环境空气中甲苯和邻二甲苯质量浓度均较高,A和B市场邻二甲苯OFP分别是环境空气的9.08、36.33倍,家居市场中活性较大的芳香烃排放对室外环境空气影响较大;通过计算获得A、B、C和D家居市场VOCs排放因子分别为86.15、257.54、239.15、308.90 g·m^(-2),年排放量分别为3.45、2.74、3.59、2.47 t。研究成果可为进一步提出家居市场VOCs科学深入管控对策提供技术支撑。
Furniture display and storage in the furniture mall gathering area is one of the main contributing sources of urban volatile organic compounds(VOCs)unorganized emissions.On-site monitoring of VOCs in furniture malls and surrounding ambient air in Jinan was conducted to analyze the VOCs emission characteristics and composition spectrum of different types of furniture malls,calculate the VOCs emission factors and emissions from different types of household markets,compared with the VOCs component characteristics of surrounding ambient air.The results showed that the highest VOCs concentration was 653.00μg·m^(−3) in low-grade furniture mall(D)in Ji’nan,followed by mid-grade furniture malls(C and B),and the lowest VOCs concentration was 149.00μg·m^(−3) in high-grade furniture mall(A).The main groups of VOCs in the malls were OVOCs,aromatic hydrocarbons,and halogenated hydrocarbons,with the highest proportion of aromatic hydrocarbons(39.05%)in low-grade furniture mall(D)and OVOCs accounted for the highest proportion in other furniture malls.The rank of furniture malls’OFP followed the order of D>B>C>A.Aromatic hydrocarbon in the home market accounted for the largest OFP.The types of VOCs from furniture malls of different grades were different in that low-grade furniture mall emitted more kinds of VOCs.Acetone,toluene,and 1,2-xylene were detected in all furniture malls.By the release of plywood-type furniture in the malls,low-grade furniture mall(D)had the highest concentration of methylene chloride at 183.00μg·m^(−3),and the other furniture malls had the highest concentration of acetone,which was related to the release from solid wood furniture and water-soluble paints in the malls.Comparing furniture malls with ambient air VOCs components revealed that toluene and 1,2-xylene concentrations were at a high level in the malls and sites.The OFP of 1,2-xylene in malls A and B was 9.08 and 36.33 times higher than that in ambient sites.The emissions of more reactive aromatic hydrocarbons in furniture malls had a greater impact on ambient air.By calculating the emissions and emission factors of furniture malls,it was found that the emission factors of VOCs were 86.15,257.54,239.15,and 308.90 g·m^(−2) for A,B,C,and D furniture malls,with annual emissions amounting to 3.45,2.74,3.59,and 2.47 t,respectively.The study of VOCs emission characteristics for the furniture malls industry in the urban area can provide technical support for further scientific and in-depth control of VOCs in the furniture malls.
