“A classroom in a conventional school with a plug-in air freshener had the highest limonene concentration (159 μg/m3 in S8C3, S stands for school ID and C stands for room ID).”

Structure

Source: Air fresheners
Factor: Limonene
Setting: classroom, US
Study design: measurement campaign in school buildings: volatile organic compounds sampled in 144 school rooms and 35 outdoor locations across conventional, EnergyStar and LEED schools, with walk-through surveys recording the sources present in each room (class 4)
Effect: other 159
Caveat: a single classroom of a conventional school, which the study labels S8C3, where S is the school identifier and C the room identifier
