This guide deals with an approach to identification, selection, and use of ecological endpoints (both assessment and measurement endpoints) that are susceptible to the direct and indirect effects of both chemical and non-chemical stressors and agents associated with wastes and contaminated media at specific sites under current and future land uses. It does not address assessment and measurement endpoints for non-site specific studies (for example, chemical specific or regional risk assessments) or measurements in abiotic media (soil, water, or air). Conditions of the site and risk assessment that should be considered in identifying and selecting assessment and measurement endpoints include stressor characteristics, ecosystem types, spatial scale, temporal scale, ecological organization, and functionality/values. The following subsections present a partial listing of representative measurement endpoints: measurement endpoints representing ecosystem assessment endpoints, measurement endpoints representing community assessment endpoints, measurement endpoints representing population assessment endpoints, and measurement endpoints representing individual organism assessment endpoints. Other general considerations, desirable characteristics of assessment and measurement endpoints, candidate site-related ecological receptors, candidate assessment endpoints, specific steps in identifying, selecting and using assessment and measurement endpoints, addressing uncertainties in the identification and selection of assessment and measurement endpoints, documenting the selection of assessment and measurement endpoints.
