Environmental Health (EH) refers to aspects of human health affected
by factors in the environment, e.g., biological factors, and
it is an essential part of any comprehensive public health system.
Similar to other health-related fields, one observes an increasing
movement in the adoption of IoT technologies into the EH domain.
Regarding the data life cycle in IoT systems, data modeling and
interpretation are crucial tasks in which ontologies are a feasible
solution because of their expressiveness and reasoning support.
In this paper, we structure the ontology-supported EH research
theme through a systematic literature mapping. The identification
and selection strategies of primary studies include the automatic
search for studies published from 2010 to 2019 on five sources
and the application of inclusion and exclusion criteria on an eighthundred-
eleven-distinct-paper group. The results of this original
work provide an overview of the research theme with multiple
classifications of thirty-four relevant studies remaining as well as
the finding of trends and gaps for future work.
