目的探讨汾河流域水重金属含量与因肿瘤死亡构成比关系。方法通过疾病控制中心收集2009年和2010年汾河流域死因监测数据,按死因分为两组:因肿瘤死亡和非肿瘤死亡。测定2008-2010年汾河流域重金属镉、铅、铜、锌含量(mg/L)。采用SPSS 13.0建数据库并进行统计描述及检验。结果因肿瘤死亡人数由2009年的第三位上升到2010年的第二位;2010年因肿瘤死亡构成比(22.26%)显著高于2009年(17.65%)。2009年镉含量(0.007 75mg/L)高于2008年(0.001 00mg/L)和2010年(0.00394mg/L);2010年铅含量(0.06630mg/L)高于2008年(0.010 00mg/L)和2009年(0.010 00mg/L)。因肿瘤死亡构成比与铅含量呈显著性正相关(r=0.846)。结论水环境铅暴露可能是引发肿瘤的危险因素之一。建议在铅污染高危地区将血铅检测作为常规指标,定期检测,同时增加锌摄入量,以降低机体中铅含量,减少肿瘤疾病发生的危险性。
Objective To investigate the relationship between water and heavy metal content in the Fenhe River Basin and the composition ratio of tumor death. Methods The data of death monitoring in Fen River Basin in 2009 and 2010 were collected through the Centers for Disease Control and Prevention. The death causes were divided into two groups: death due to tumor and non-tumor death. Determination of heavy metal cadmium, lead, copper, zinc content (mg / L) in Fen River Basin in 2008-2010. Using SPSS 13.0 to build a database and carry out statistical description and testing. As a result, the number of cancer deaths rose from the third place in 2009 to the second place in 2010; the proportion of cancer deaths in 2010 (22.26%) was significantly higher than that in 2009 (17.65%). In 2009, the content of cadmium (0.007 75mg / L) was higher than that in 2008 (0.00100mg / L) and in 2010 (0.00394mg / L); the content of lead in 2010 was 0.06630mg / L higher than that in 2008 (0.01000mg / L) And 2009 (0.010 00mg / L). There was a significant positive correlation between the constituent ratio of tumor death and the lead content (r = 0.846). Conclusion Lead exposure to water environment may be one of the risk factors of tumor initiation. Proposed in the lead-contaminated areas of blood lead testing as a general indicator of regular testing, while increasing zinc intake, in order to reduce the body’s lead content and reduce the risk of tumor disease.
