Welcome! We are under construction.
Community Exposure Science (CES), also known as Citizen Exposure Science or Participatory Exposure Science, is an endeavor in which everyday people conduct scientific investigations to elucidate the nature of exposure to toxic environmental agents in their community, including measures of absolute exposure, mechanisms of exposure, impacts of exposure, and approaches to mitigation. CES is a sub-area of Community Science, also known as Citizen Science, community-based research, voluntary research, community-based participatory research, or "observations made by the public".
Exposure Science is the study of how people or other systems come into contact with potentially toxic environmental agents that may cause system changes, including short or long-term adverse health outcomes. Exposure Science is essential for identifying the mechanisms of exposure, disease, and disease prevention. Visit the Exposure Science website or the International Society of Exposure Science to learn more.
The purpose of this website is to support the public and specific communities in conducting exposure investigations in their community using free and low-cost tools. This website hosts the Personal Exposure Toolkit (PET), consisting of free apps and web portals and integration with a low-cost personal exposure monitor (the Atmotube PRO). Read the PET FAQ. This website also serves as a hub for guides on how to conduct Exposure Science studies and a repository containing the methods and results of ongoing Community and Citizen Exposure Science studies.
The maintenance of this website is led by Dr. Neil Klepeis and other members of the Community Exposure Science Collaborative (CESC) (see descriptions of collaborators). Dr. Klepeis founded the CESC and is supported by state and federal grants at San Diego State University Research Foundation (SDSURF) and also works with ETR Inc. on community engagement projects and in industry R&D as part of his Machine Contingencies firm. The CESC is a group of collaborators at organizations involved in coordinating or developing tools for community projects and mandates related to air quality, tobacco prevention, and overall environmental health and well-being.
This website exists to serve the public. The public, as well as career scientists, are encouraged to participate and collaborate by contributing materials, resources, guides, and, especially, by performing exposure science studies and reporting back so we can post about them.
