Re: What is more toxic - gasoline or gasoline exhaust?

Like I said, there are a few more listed in the MSDS that are not common to all gasoline but are manufacturer specific. Lead would be a big one. Leaded gasoline still exists and the health consequences of lead are very well known.

The most obvious decomposition products for gasoline are carbon monoxide (CO), carbon dioxide (CO_2), and water (H_2O).

But, I would imagine there are others such as oxides of nitrogen and sulfur. The most dangerous is clearly carbon monoxide which can kill a person very quickly. Sulfur dioxide also isn't a good thing to be breathing. I'll try and find a list of the decomposition products as I'm just kind of guessing at these.

Also - any one of the ingredients listed in the MSDS and the table above should be considered present in the exhaust. In other words: the exhaust is going to have benzene.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
