The International Society of Exposure Science was founded in 1989 aiming at the advancement of the science of exposure assessment related to environmental contaminants, both for human populations and ecosystems. Its objective is to foster and advance exposure science related to environmental contamination in human populations and ecosystems; promote communication among exposure analysts, epidemiologists, toxicologists, and other scientists; recommend approaches to substantive or methodological concerns; and strengthen the impact of exposure assessment and analysis on environmental policy. In specific, ISES is:

• A specialty society focused on understanding the complex inter-relationships between human populations and communities, ecosystems, wildlife, and chemical, biological, radiological and other physical stressors, be they natural or be they anthropometric (in practise, ISES has focussed strongly on chemical stressors).

• An influential professional society with a mission to serve our members and advance the field of exposure science. Membership to ISES will make a difference in furthering this mission and having opportunities to meet others who share the passion for exposure science.
