天津地区致癌风险的预期寿命损失分析

Loss of Life Expectancy Analysis for Cancer Risk in Tianjin Area

预期寿命损失是健康风险评价统一的指标 .本文根据天津的人口统计数据和有关资料求算了天津地区特定致癌风险条件下预期寿命损失 .结果表明 ,单位致癌风险 (10 -5)的污染物暴露下 ,天津地区男性和女性平均预期寿命损失分别为 5 8 4 7min和 6 6 82min .同时发现本底癌症发病率是预期寿命损失的决定因素 ,而相关参数对结果影响较小 .

Loss of Life Expectancy was proposed as the single metric for health risk assessment. Based on the statistical data of population in Tianjin, it was calculated that the unit cancer risk (10 -5) equivalents to 58.47 and 66.82 minutes of life expectancy loss for male and female, respectively. The results depend strongly on the background rate of cancer, with little response for associated parameters.
