摘  要:目的 研究社区人群多种金属的内暴露水平与肺功能的关联,并探讨可能存在的剂量反应关系。方法 采用横断面研究方法,在2011年4—5月期间在武汉市2个社区招募在本地区居住不少于5年的居民,进行问卷调查和体格检查,测定肺功能情况,收集晨尿样本,共有2 540名研究对象完成了调查。采用电感耦合等离子体质谱联用仪(ICP-MS)检测研究对象尿液中23种金属水平,应用单因素和多因素线性回归分析金属内暴露水平与肺功能的关系。结果 研究对象的平均年龄为52.8岁,校正肌酐后,尿中钴、铜、锌、镍、锑、钡、铅浓度的几何均数分别为0.02、0.68、23.80、0.20、0.10、0.34、0.26 μg/g肌酐。单因素线性回归分析显示,尿中钴、铜、锌、锑每增加一个对数单位,用力肺活量(FVC)下降,分别下降0.091(95%CI: -0.155~-0.027)、0.101(95%CI: -0.178~-0.025)、0.094(95%CI: -0.172~-0.027)、0.118(95%CI: -0.203~-0.033)L;尿中钴、镍、锶、锑、钡、铊、铅每增加一个对数单位,一秒钟用力呼气容积(FEV1)下降0.070(95%CI: -0.124~-0.016)、0.063(95%CI: -0.118~-0.007)、0.063(95%CI: -0.124~-0.002)、0.092(95%CI: -0.164~-0.020)、0.055(95%CI: -0.105~-0.005)、0.081(95%CI: -0.148~-0.014)、0.097(95%CI: -0.151~-0.042)L。多因素线性逐步回归分析显示,随着尿中钴、铜、锑浓度的增加,FVC水平呈下降趋势,β值分别为0.073(95% CI: -0.146~-0.001)、-0.104(95%CI: -0.202~-0.006)、-0.190(95%CI: -0.315~-0.065)L;而随着尿金属钒、铀浓度的增加,FVC水平呈上升趋势,β值分别为0.126(95%CI: 0.037~0.216)、0.106(95%CI: 0.021~0.192)L。随着尿中钴、锑、钡、铅浓度的增加,FEV1水平呈下降趋势,β值分别为-0.067(95%CI: -0.129~-0.005)、-0.142(95%CI: -0.247~-0.037)、-0.073(95%CI: -0Objective To investigate the association between levels of 23 urinary metals and lung function, and explore their does-response relationships in the general population of Wuhan province, China.Methods This was a cross-sectional study that enrolled volunteers from two communities of Wuhan between April and May 2011. All volunteers had resided in Wuhan for at least 5 years. Information from questionnaires and physical examinations were collected and lung function was assessed. Data from 2 540 volunteers were included. Urinary levels of 23 metals were measured by inductively coupled plasma mass spectrometry (ICP-MS). The relationship between urinary metals and lung function was analyzed with single and multiple regression models.Results The mean age of the study population was 52.8 years. Mean levels of urinary metals, after adjustment for creatinine, including cobalt, copper, zinc, nickel, antimony and barium were 0.02, 0.68, 23.80, 0.20, 0.10, 0.34 and 0.26 μg/g creatinine, respectively. There were significant concentration-response relationships between increases in some urinary metals and reduced lung function. Single-metal regression models demonstrated that for each 1-unit increase in urinary levels of cobalt, lncopper, lnzinc, lnantimony, there was a reduction in forced vital capacity (FVC) of 0.091 L (95%CI: -0.155--0.027), 0.101 L (95%CI: -0.178--0.025), 0.094 L (95%CI: -0.172--0.027) and 0.118 L (95% CI: -0.203--0.033), respectively. Each 1-unit-increase in urinary lncobalt, lnnickel, lnstrontium, lnantimony, lnthallium, lnlead was associated with a reductions in forced expiratory volume in 1 sec (FEV1) of 0.070 L (95%CI: -0.124--0.016), 0.063 L (95%CI: -0.118--0.007), 0.063 L (95%CI: -0.124--0.002), 0.092 L (95%CI: -0.164--0.020), 0.055 L (95%CI: -0.105--0.005), 0.081 L (95%CI: -0.148--0.014), and 0.097 L (95% CI: -0.151--0.042), respectively. With respect to metal co-exposure, FVC was significantly associated with elevated
