    兰州市西固区居民饮水量调查

    Survey on Drinking Water Consumption of Residents in Xigu District, Lanzhou City

      摘要
    • 摘要:
      目的 了解兰州市西固区居民饮水量，为西固区居民饮用水健康风险评价提供科学依据。
      方法 于2017年夏季（7月）、冬季（12月）采用整群随机抽样的方法，从西固区选取18岁及以上常住居民240名，通过问卷调查和标准量具相结合的方法进行饮水量调查，采用美国环保局公式计算西固区和中国不同性别人群饮用水污染物暴露剂量。统计学分析采用Wilcoxon秩和检验和Kruskal-Wallis秩和检验。
      结果 西固区居民全年日均总饮水量、直接饮水量、间接饮水量中位数分别为2 161、1 800和430 mL/d。男性全年总饮水量和直接饮水量（2 404和2 000 mL/d）均高于女性（2 143和1 700 mL/d）（P < 0.05）；不同年龄人群中，（45~64）岁人群的全年总饮水量、直接饮水量和间接饮水量（2 502、2 000和521 mL/d）最高，其中不同年龄人群的总饮水量和间接饮水量差异有统计学意义（P < 0.05）；且冬季不同年龄人群的间接饮水量差异也有统计学意义。西固区的女性饮用水污染物暴露剂量较男性高10.7%；西固区男、女性的饮用水污染物暴露剂量分别较中国同性别人群高6.5%、20.2%。
      结论 西固区饮水健康风险评价应采用本地区暴露参数，同时考虑性别等因素的影响。

       

      Abstract:
      Objectives To understand the drinking water intake of residents in Xigu District, Lanzhou City, and to provide the basic data for health risk assessment of drinking water in Xigu District.
      Methods A total of 240 adult residents were randomLy selected by multiple-stage stratified cluster from Xigu District in July and December, 2017. The information on drinking water intake of residents was investigated by using quantitative measurement and questionnaire survey. Exposes doses of drinking water pollutant were counted by using model equation of US EPA. Wilcoxon rank sum test and Kruskal-Wallis rank sum test were used for stratified analysis of drinking water intake.
      Results The medians of total drinking water intake, direct drinking water intake and indirect drinking water intake of residents were 2 161, 1 800 and 430 mL/d in Xigu District, respectively. The total drinking water intake and direct drinking water intake of male (2 404, 2 000 mL/d) were all higher than that of female (2 143, 1 700 mL/d) (P < 0.05). The total drinking water intake, direct drinking water intake and indirect drinking water intake of population aged (45~64) years old were 2 502 mL/d, 2 000 mL/d and 521 mL/d, respectively, which were the highest values among all subjects, and there were statistically significant in the total drinking water intake and indirect drinking water intake among the different aged people. The result also showed that exposes doses of drinking water pollutant increased 10.7% in the female in comparison of male in Xigu District. The exposes doses of drinking water pollutant increased 6.5% and 20.2% in male and female in Xigu District in comparison of the same gender population in China.
      Conclusions The local exposure parameters should be use to the health risk assessment of drinking water in Xigu District. Gender and age should be taken into account in health risk assessment.
