The solid rod of the pencil is graphite, not graphene. You can make a bit of graphene from the graphite by using sticky tape, I read. I'm not sure how much graphene "pollution" would appear spontaneously when using a pencil in a normal way.
- labster 4y agoHave you never used a pencil sharpener before? Never smelled the sweet aroma of sawdust and shaved graphite? You break it up on purpose, that has to release some graphene sheets.
- kergonath 4y agoThe parent's point was that graphene was harmless because graphite is widely used. Graphite is just a lot of graphene layers stacked on top of each other. Pretty much no dangerous particles are emitted during normal use of a pencil, which was part of the point.
