【摘要】 目的通过对毗邻广州李坑生活垃圾焚烧发电厂的某村在建厂前后的恶性肿瘤发病的流行病学调查,初步评价垃圾焚烧对居民癌症的影响。方法从当地公安部门收集所在村2003-2008年的人口数、居民名册、户籍迁移登记和居民死亡资料,检索广州地区171间医院住院记录和新型农村合作医疗报销资料获得该村和白云区恶性肿瘤发病资料,对该村诊断或死因不明病例入户调查,死亡病例进行死因回顾性调查。结果该村在建厂前3年居民年平均死亡率579.3/10万,建厂后3年年平均死亡率526.2/10万,差异没显著意义(X~2=0.14 3,P=0.706)。恶性肿瘤发病率前后分别为176.8/10万、17 7.0/10万,统计学检验无显著性差异(X~2<0.001,P=0.996)。该村2006-2008年恶性肿瘤平均标化发病率为119.6/10万,白云区相应的标化发病率为202.5/10万,标准化率比为0.59(95%CI=0.40 0.87),两率间比较有显著意义(X~2=7.046,P=0.008)。结论没发现垃圾焚烧发电厂致周边居民癌症高发的流行病学依据。更多还原

【Abstract】 Objective To understand the cancer risks of municipal waste incineration by epidemiologic investigation of malignant tumor incidences in a village neighboring Likong Municipal Waste Incinerator in Guangzhou.Method Demology and death data for the village from 2003 to 2008 were collected local police departments.Malignant tumor incidences of the village and Baiye district were gathered from inpatient records of 171 hospitals in Guangzhou and New Peasant Medical Insurance System.Home visitations were paid when diagnosis was not explicit and the Verbal Anatomy were implement for the death.Results The village was with an average mortality of 579.3/10~5 for 3 years before the incinerator’s operation,and 526.2/10~5 for 3 years after the incinerator’s operation respectively.The difference is not meaningful statistically(x~2=0.143,P=0.706). The average incindences of malignant tumour for 3 years before or after the incinerator’s operation in the village were 176.8/10~5 and 177.0/10~5 respectively.The difference is not meaningful statistically (χ~2<0.001,p=0.996).After standardized,the average incidences of malignant tumors from 2006 to 2008 was adjusted to 119.6/10~5 for the the village and 202.5/10~5 for Baiyun district.The Standard Rate Ratio was 0.59(95%CI=0.40～0.87) and the difference between these two incidences is meaningful statistically(x~2=7.046,p=0.008).Conclusion The epidemiologic correlation between municipal waste incineration and cancer risk was not found.更多还原
