Diesel Soot in Buses

[Guest guest]

I forward the Bruce Rundlett, BBEC piece on the diesel soot for buses to a

friend, author/professor ( Ford) in the UK.

His response was:

The school buses in the USA are often dirty and do spew out submicron

hydrocarbon particulates that are known to be carcinogenic.

BUT claiming that they flood the passenger compartment with fumes is

journalistic license, and is sheer drivel.

However, I don't know of any European truck that has its exhaust where the

writer claims; they are vertical, a bit like the US trucks. As for the

itty-bitty cars . . . Europeans don't like to contribute to the pollution of the

air, as the USA does; hence the more modest choice of car. But if your

correspondent wanted to rent something not so itty-bitty he'd find a range of

superb cars to choose from: BMWs and Mercedes, Rolls-Royce and Jaguar; the

choice is all here!

As for the fume-filled school buses? It's all crap. But it's not half as bad as

the average misrepresentation of science stories that catch my eye . . .

See you at I/M? Hope so.

Best,

Lots of great questions. I e-mailed Medical News Today. The editor and I have

been having a conversation about this article. It seems that it is coming over

the wire and they were not the source. It is in hundreds of US newspapers.

Whoever wrote this needs to do some homework. There may be some agenda going on

here. I can't believe the school bus fleet is that old and ill maintained.

The part about the " open crankshaft " was pulled from the Medical News Today

article an hour after it went out. The editor checked the article with his

mechanic, who laughed at the crankshaft comment just as I had, so he took it

out. The mechanic said that the problem he sees there (UK) is that the busses

are very large for the streets and get stuck in traffic for extended periods.

The original article is much more sensible, offering facts and solutions.

Crankshafts and soot filled busses are not mentioned. The article is rather

positive.

Here is the original version:

http://www.ucsusa.org/clean_vehicles/big_rig_cleanup/clean-school-bus-

pollution.html

Here is the LA Times version:

http://www.latimes.com/news/nationworld/nation/la-na-

schoolbus25may25,1,3677284.story?coll=la-headlines-nation

It is apparent that someone sensationalized the report and " made up " (?) or

misrepresented a lot. It is sad that this is not unusual any more. It seems

that most of what we are debating about this article is not in the article, but

is fiction.

As for the original question: Just how does a school bus fill with diesel soot?

It has help from someone shoveling BS.
