Finding F-1499

“A total of 62 VOC substances were identified in chamber studies using ABS and PLA filaments; for example, styrene had an emission rate of 0.29–113.10 μg/min, and isopropyl alcohol had an emission rate of 3.55–56.53 μg/min.”

Structure

Factor: Styrene
Setting: test chamber
Study design: review of the emission characteristics of volatile organic compounds released during material extrusion printing with ABS and PLA filaments in chambers, laboratories and workplaces, with the influencing factors compiled (class 5)
Effect: emission-rate 113.10
Caveat: a range compiled by a narrative review, not one measurement; 62 volatile compounds were identified across the chamber studies

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.
