"Dry-erase" white-boards are now commonly used, especially in computer-rich
classrooms, supposedly to keep chalk-dust from damaging computer
disk-drives. But, these boards also produce dust, albeit blue and red
instead of white. We've noticed that keyboards in these classrooms develop
colorful patterns over time! Also, the solvent used in the ink in these
markers smells, and some folks may find this an irritant, some may even be
allergic.
Are these boards really "better" in the computer-rich classroom? Is there
any reason to suspect the markers as a potential health hazard?
