Because Apple wasn't monitoring its solvent emissions, & had no permit, its unclear just how much toxic waste Apple dumped into our bedrooms.
Also, it gets worse. Between 2020-23, Apple did monitor the air for vapors with an ad hoc, handheld, calibrated gas detector...ONE TIME.
Apple failed to calibrate the tool in all other tests. However, Apple did calibrate the tool a few times, but each time Apple then failed to actually use the tool to test anything. Great work, Apple.
