Benzene

thingiverse

Benzene, including hydrogen atoms, remains a widely utilized solvent in laboratory settings, despite controversy surrounding its potential link to leukemia. Researchers found it present in nearly all labs before concerns over its carcinogenic effects came to light. Meanwhile, exposure to benzene is not limited to laboratory use, as individuals inhale it through cigarette smoke and it is also a natural component of crude oil and gasoline. Given that the maximum allowed tolerance for an 8-hour workweek of 40 hours is only 1 part per million, today's scientists often wear protective gear in the lab when working with benzene.
