  • 摘要: 大气沉降是室内灰尘的重要来源.本研究于2017年1-2月采集了河南省12个城市的室内灰尘样品共48个，并按照取样城市的空间分布探讨了重金属（Ni、Cu、Zn、Mn、Co、Cr、As、Ag、Cd、Pb）污染的南北差异（以黄河为界）.运用地积累指数法对其进行污染评价.应用美国EPA人体暴露风险模型进行健康风险评价.结果表明，豫南城市室内灰尘中重金属除Pb以外平均浓度均显著高于豫北城市.豫南城市重金属平均浓度表现为Zn > Mn > Cr > Ni > Pb > As > Cu > Co > Cd > Ag，浓度大小依次是306.7、249.2、223.3、116.9、55.7、41.6、30.3、7.0、1.8、1.3 mg·kg-1，而豫北城市重金属浓度表现为Zn > Mn > Pb > Cr > As > Ni > Cu > Co > Cd > Ag，浓度大小依次是200.7、179.4、85.4、48.7、22.9、22.1、21.4、4.4、2.6、0.7 mg·kg-1.地累积指数结果显示Cd在豫南和豫北城市均是重污染和极重污染，而Ag在豫南城市是重污染和极重污染.豫南城市室内灰尘中4种致癌重金属的致癌风险大小依次为Cr > As > Ni > Cd，6种非致癌重金属的非致癌风险大小依次为Zn > Mn > Cu > Pb > Co > Ag；豫北城市室内灰尘中致癌重金属的致癌风险依次为Cr > As > Ni > Cd，非致癌重金属的非致癌风险依次为Zn > Mn > Pb > Cu > Co > Ag.
    Abstract: Atmospheric deposition is an important source of indoor dust. In this study, a total of 48 indoor dust samples from 12 cities in Henan Province were collected and the pollution characteristics of heavy metals (Ni、Cu、Zn、Mn、Co、Cr、As、Ag、Cd、Pb) were investigated, according to the spatial distribution of the sampling cities (bounded by the Yellow River). Geo-accumulation index was used to evaluate the contamination level of heavy metals, and human health risk assessment was conducted by means of the USEPA model. The results showed that the average concentrations of heavy metals in the urban indoor dust of sourthern Henan was significantly higher than those for the northern Henan cities. The concentrations of heavy metals in the cities of southern Henan are in the order of Zn > Mn > Cr > Ni > Pb > As > Cu > Co > Cd > Ag, and that of northern Henan ranked Zn > Mn > Pb > Cr > As > Ni > Cu > Co > Cd > Ag. The results of the cumulative index indicated that Cd was heavily polluted in the southern and northern Henan cities, and Ag in the southern Henan cities was also heavily polluted. The carcinogenic risk of the four carcinogenic heavy metals in the cities of sourthern Henan was in the order of Cr > As > Ni > Cd, and the non-carcinogenic risk of the six non-carcinogenic heavy metals was in the order of Zn > Mn > Cu > Pb > Co > Ag. The carcinogenic risk of carcinogenic heavy metals in the cities of northern Henan ranked as Cr > As > Ni > Cd. The non-carcinogenic risk of non-carcinogenic heavy metals was sorted by Zn > Mn > Pb > Cu > Co > Ag.
