The National Exposure Registry was created in response to the pervasiveness of chemical contamination at the nation's waste sites and the relative lack of information on human health outcomes associated with long-term, low-level exposure to most of these substances. A ranking scheme was developed by the Agency for Toxic Substances and Disease Registry (ATSDR) to select the substances for which substance-specific subregistries of the National Exposure Registry would be developed. This scheme uses a general decision analysis approach that incorporates the most relevant and up-to-date data available on the substances found at sites known to ATSDR. There are currently four general subregistries (volatile organic compounds, dioxins, heavy metals, and radioactive substances) made up of persons exposed to specific primary contaminants, as selected by means of this ranking scheme.
国家暴露登记处的设立是为了应对美国垃圾场普遍存在的化学污染问题，以及对于大多数此类物质长期低剂量暴露所产生的人类健康后果相关信息相对匮乏的状况。有毒物质和疾病登记署（ATSDR）制定了一个排名方案，以挑选出将为其建立国家暴露登记处特定物质子登记处的物质。该方案采用了一种通用的决策分析方法，纳入了ATSDR所知场所中发现的物质的最相关和最新数据。目前有四个一般子登记处（挥发性有机化合物、二恶英、重金属和放射性物质），由通过此排名方案选定的接触特定主要污染物的人员组成。
