Overview

The International Society of Exposure Science (ISES) is a nonprofit professional organization devoted to the development and application of exposure science. The society was established in 1990 under the name International Society of Exposure Analysis, later adopting its current name as the field broadened and exposure science became the more widely used description of its work. Its formation followed a period of growing scientific interest in understanding how people and ecosystems encounter chemical, biological, physical, and other environmental agents. Meetings and workshops organized through a National Research Council process beginning in 1987 helped establish foundational concepts and principles for exposure assessment, providing part of the intellectual background for the society’s creation. ISES brings together researchers and practitioners from a wide range of disciplines. Its community includes specialists in exposure assessment, environmental chemistry, toxicology, epidemiology, risk assessment, biochemistry, physiology, bioinformatics, ecology, and environmental engineering. Membership also spans universities, government agencies, private companies, and public-policy institutions. This mix reflects the society’s focus on connecting measurement and modeling of exposures with health, environmental, and regulatory questions. The organization’s activities center on professional and scientific exchange. ISES convenes an annual conference, sometimes jointly with other international scientific societies, and provides a forum for presenting research, discussing methods, and examining emerging exposure concerns. Conference themes have included pollution, environmental epidemiology, indoor and outdoor environments, electronic waste, natural disasters, and effects on built, natural, and social environments. The society has also been associated with the Journal of Exposure Science and Environmental Epidemiology, a publication serving the broader exposure-science research community. ISES is governed through elected and appointed leadership structures that include a president, president-elect, treasurer, secretary, and councilors. Council representation is organized to reflect important segments of the membership, including academic, governmental, private-sector, and student participants. The membership approved the organization’s first bylaws in 1991, establishing an early formal framework for governance and representation. The society also supports professional recognition through awards. These include the Jerome J. Wesolowski Award for contributions to the knowledge and practice of human exposure assessment; the Joan M. Daisey Outstanding Young Scientist Award for an early-career researcher in exposure science; the Constance L. Mehlman Award for work that has influenced policy or introduced approaches to reducing or preventing exposures; and a Distinguished Lecturer Award honoring an individual who advances the society’s mission and goals. Taken together, these programs position ISES as a convening and professional-development organization rather than a commercial product brand. Its principal outputs are scientific meetings, disciplinary networks, knowledge exchange, recognition programs, and support for the exposure-science field.

History

The International Society of Exposure Science was established in 1990 as the International Society of Exposure Analysis. Its creation emerged from a period in which scientists were working to define exposure assessment as a distinct and methodologically rigorous area of environmental and health science. A National Research Council process that began with meetings and workshops in 1987 helped articulate principles that later supported the development of exposure science as an interdisciplinary field. Paul Lioy was among the scientists and engineers involved in forming the society. The organization’s original emphasis was exposure analysis: identifying, characterizing, and quantifying contact between people or ecological systems and environmental agents. Over time, the field expanded beyond analytical measurement to incorporate modeling, biological and physiological understanding, toxicology, epidemiology, environmental chemistry, risk assessment, and computational methods. The society subsequently became known as the International Society of Exposure Science, a name that better reflected the breadth of the discipline and its connection to environmental health and policy. ISES adopted its first bylaws in 1991. Its governance model included a president, president-elect, treasurer, secretary, and elected councilors. Council representation was designed to account for the society’s professional diversity, including academic researchers, government scientists, private-sector participants, and students. This structure supported the organization’s role as a cross-sector forum rather than a body limited to one profession or institutional type. A central continuing activity has been the annual scientific conference. ISES has periodically organized meetings in cooperation with other international societies, allowing exposure science to be examined alongside environmental epidemiology, indoor-air research, and related fields. In 2018, the society joined the International Society for Environmental Epidemiology for a meeting in Ottawa, Canada. The program addressed a wide range of exposure topics, including electronic waste and natural disasters. In 2019, ISES partnered with the International Society of Indoor Air Quality and Climate for a conference in Lithuania that considered air pollution and impacts on built, natural, and social environments. The society is also associated with the Journal of Exposure Science and Environmental Epidemiology, which provides a publication venue relevant to its disciplinary community. Through meetings, professional networks, journal connections, and awards, ISES supports the production and dissemination of research that can inform environmental-health practice and public policy. Its awards program has developed several forms of recognition. The Jerome J. Wesolowski Award honors contributions to human exposure assessment. The Joan M. Daisey Outstanding Young Scientist Award recognizes an early-career exposure scientist whose degree was awarded within the preceding decade. The Constance L. Mehlman Award recognizes exposure-analysis contributions that have helped shape national or state policy or introduced new approaches to reducing or preventing exposures. A Distinguished Lecturer Award recognizes an individual who promotes the society’s mission and goals. The available reference material does not provide a complete chronology of later officers, conference editions, membership figures, financial information, or current organizational initiatives. ISES is nevertheless documented as an ongoing international professional society whose principal mission is to advance exposure science through interdisciplinary collaboration, scientific communication, and professional recognition.
