Apple Denies Reports of Mac Pros Emitting Toxic Fumes

Earlier this week, a report posted to a French newspaper claimed that an odor being emitted from some Mac Pros could actually be toxic fumes.

A scientist quoted in the article says the odor contains several toxins, including benzene. Prolonged exposure to benzene raises the risk for diseases, including cancer.

An Apple spokesperson spoke to Macworld and stated that they have not found any evidence to prove this claim, but states they will continue to investigate it.

A strange startup odor has been noted by some Mac Pro owners on Apple's discussion forums.
