摘　　要：目的了解甘肃省兰州市城区成年居民饮用水暴露参数,为兰州市城区居民饮用水健康风险评价提供基础依据。方法于2017年7—8月和12月采用整群随机抽样方法在兰州市城关区、七里河区、西固区和安宁区4个城区抽取1236名≥18周岁成年居民进行饮水量和涉水活动皮肤暴露参数调查。结果兰州市城区成年居民直接饮水量、间接饮水量和总饮水量中位数分别为1650、394和2142 mL/d,不同性别、年龄、体质指数(BMI)城区成年居民直接饮水量、间接饮水量和总饮水量不同,不同职业城区成年居民间接饮水量不同,差异均有统计学意义(均P<0.05);兰州市城区成年居民皮肤表面积为1.746 m2,其中男性和女性分别为1.846和1.646 m2,18~44、45~64岁和≥65岁者分别为1.731、1.783和1.709 m2;兰州市城区成年居民日常生活活动的皮肤总涉水时间为76.51 min/d,其中洗脸、洗手、洗头、洗脚、洗澡、洗碗、洗菜、洗衣服的皮肤涉水时间分别为5.67、6.26、6.24、12.75、14.34、13.18、11.97、6.10 min/d,不同性别、年龄和职业成年居民部分日常生活活动的皮肤涉水时间差异均有统计学意义(均P<0.05)。结论不同性别、年龄、BMI和职业对兰州市城区成年居民饮水暴露参数有影响。Objective To examine drinking water intake and daily life water usage among urban adult residents in Lanzhou city of Gansu province and to provide basic data for estimating domestic water-related exposure parameters for health risk assessment.Methods A total of 1236 residents aged 18 years and older were randomly selected with stratified multistage cluster sampling from four urban districts in Lanzhou for a questionnaire survey during July–August and December,2017.Information on drinking water intake and dermal exposure parameter-related to water usage were collected and analyzed.Results The medians of direct,indirect,and total drinking water intake were 1650 mL/d,394 mL/d and2142 mL/d among the respondents,respectively;the three medians differed significantly by gender,age,and body mass index(BMI)groups and the median for indirect drinking water intake was significantly different among the respondents with various occupations(P<0.05 for all).The average body surface area was 1.746 m2 for all the respondents and the average area was 1.846 m2 and 1.646 m2 for the male and female respondents,and 1.731 m2,1.783 m2 and 1.709 m2 for the respondents aged 18–44,45–64 and over 65 years old,respectively.The total time of water-related daily activity of the respondents was 76.51 minutes per day(min/d);the time water-related daily activity was 5.67,6.26,6.24 and 12.75 min/d for washing face,hands,head and feet,14.34 min/d for bathing,13.18 and 11.97 min/d for washing dishes and vegetables,and6.10 min/d for washing clothes,respectively;the times of water-related daily activities differed significantly by gender,age and occupation among the respondents(all P<0.05).Conclusion Gender,age,BMI and occupation may influence drinking water intake and daily life water usage among adult urban residents in Lanzhou city.
