You mean that there's a nuclear reaction that takes place when alkyl lead compounds are burned, and the lead magically becomes not lead any more ?
Rubbish
The lead was removed so that catalysts could be employed to reduce smog.
As to benzene, it's still used up to 5% (neat), and less than 50% aromatics.
When fuel is burned, benzene WILL be present in the exhaust, often when it isn't even in the fuel in the first place.
If alcohols are burned, the results typically contain a lot of aldehydes, which are pretty carcinogenic.
