中文摘要：

为了解我国人群邻苯二甲酸二丁酯（DBP）的健康风险负荷，在国内外文献分析和现场监测数据的基础上，对我国DBP的人群暴露状况进行评估．结果表明．DBP广泛存在于环境和人体生物样品中，估计每日总摄入量为14．8μg／（kgd），食物是其主要的摄入途径，占总摄入量的90．2％．其次为饮用水，占8．6％；说明我国人群DBP的污染已达一定负荷．

英文摘要：

The purpose of this study was to estimate the body burden of di-n-butyl phthaltate exposure on Chinese population, based on environmental monitoring data and related literatures. Di-n-butyl phthalate could be detected in most of environmental and biological samples collected from the Yangtzi River Delta area. The estimated total intake of di-n-butyl phthalate from various routes was 14.8μg/（kg·d）, from which diet and drinking water accounted for 90.2% and 8.6% of total daily intake, respectively. Di-n-butyl phthalate played an important role in environmental pollution in the Yangtzi River Delta area. Policy-makers must make managements to control or decrease the environmental levels of phthalate pollution.
