Description:Guidance on Identifying Exposure Units, V1 — Sept 19, 2020
Environmental contamination is found over many different geographical scales, from small localized areas caused by spills to widespread contamination from decades of environmental releases. Many factors influence how people may contact this contamination. For instance, daily routines, personal preferences, cultural practices, permanent fences, and natural barriers all affect where people frequent. Health assessors must bridge both types of information—environmental contamination information and how people come in contact with the contamination in order to evaluate whether exposures present public health hazards. One step in this process is identifying exposure units, which are defined as physical areas where a person’s activities result in contact with a contaminated environmental medium.
This document presents ATSDR’s guidance for defining exposure units for use in the public health assessment process.
