泌阳地区居民冬季饮水暴露参数研究

Abstract

目的了解我国北方地区冬季的饮水率状况,并与该地区夏秋季研究结果对比,探讨饮水率的季节差异性。方法 2009年2—3月,采用问卷调查与实际测量相结合的方法,在夏秋季对河南泌阳调查的2 500人基础上抽取1 000人对冬季饮水情况进行研究,主要包括居民的直接饮水和食物间接饮水的摄入情况,并与夏秋季结果进行比较。结果该地区居民冬季总饮水率均值为1 507.9 ml/d,比夏秋季低44.6%,直接饮水率和间接饮水率均值分别为224.1、1 283.9 ml/d,分别比夏秋季低78.2%,24.5%,且均具有季节性差异,同时在城市和农村居民中也有显著的季节性差异。结论进行饮水健康风险评价时需考虑季节因素..
