Links to other glossaries that define terms related to exposure and risk assessment are provided below, including the glossary developed by the International Programme on Chemical Safety (IPCS) and the Organisation for Economic Cooperation and Development (OECD). These groups joined together to "develop internationally harmonized generic and technical terms used in chemical hazard/risk assessment." IPCS and OECD sought to define both generic terms and terms related to specific technical fields. As part of this effort, the Exposure Assessment Terminology Working Group developed a glossary of exposure assessment terminology to help facilitate communication and promote consistency of language in exposure science.
