Structure

Factor: Airborne fungi
Setting: classroom (empty)
Study design: study of indoor air bioaerosols in classrooms across the wet and the dry season: total fungal and total bacterial counts sampled outdoors, in empty classrooms and in occupied classrooms, with the respirable fractions measured separately (class 4)
Effect: median 53.0
Caveat: culturable fungi only, counted as colony-forming units

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
