Notice of availability and request for public comment on the draft online learning program, Identifying Exposure Pathways.


This program was developed to provide environmental and public health professionals information about the ATSDR public health assessment process through simulation and interactive learning using the Internet. The program provides learn-by-doing steps on how ATSDR's cooperative agreement partners (agents of ATSDR), ATSDR staff, and other environmental and public health professionals can identify how persons come into contact with hazardous and toxic substances. This program is an interactive simulation involving internal and external communications, site document review, mock site review, video clip review, community involvement activities, and completion of an exposure pathway table.

ATSDR conducts public health assessments to evaluate whether people have come in contact with hazardous substances released into the environment and whether contact with the substances has affected the health of people exposed to those substances.

The process used to conduct public health assessments includes gathering information from community members about how they might have come in contact with hazardous substances released into the environment and the concerns they have about the effect of the substances on their health. In addition to information gathered from community members, ATSDR also evaluates environmental data pertaining to the release, evaluates toxicologic and epidemiologic data relevant to exposures, and evaluates existing health outcome data if appropriate. Recommendations might be made to eliminate or reduce exposure to harmful levels of hazardous substances that have been released into the environment. The online learning program provides information on the basic concepts used by ATSDR staff and agents of ATSDR in conducting public health assessments, specifically how to identify pathways of exposure.

This online learning program is intended to assist environmental public health professionals understand the basic steps and coordination necessary to identify exposure pathways. It is part of the exposure evaluation component of the public health assessment process. Because interaction with the public's environmental public health professionals is a critical component of the public health assessment process, ATSDR believes that public comments may help us improve the quality of the program. All comments received during the public comment period will be considered when making improvements to the program.

Availability: The draft online program, Identifying Exposure Pathways, will be available to the public on or about August 29, 2003. The public comment period will begin on the date the program is first available on the ATSDR Web site. The close of the public comment period will be 60 days from the date of publication and will be indicated on the first page of the Web site.
