Frameworks
An IEHM programmeshould be based on a structured framework to enable simultaneous monitoring and interpretation [8].
A framework provides a systematic approach that helps identifying links or relationships between the environment and human health to interpret complex E&H issues. Indeed, the main role of a framework is to organize the concepts, ideas, and notions of an activity meaningfully [9], in order to recognize and interpret complexlinks between the elements of the activity [10].
