Report: Diesel fumes stress your brain
Posted on Tuesday 11 March 2008


Diesel fueled cars are already associated with the negative image of heavy trucks clogging the air with their dark and sooty exhaust plumes, and a new study only goes further to damage it’s reputation. Dutch scientists have found that breathing diesel exhaust fumes can trigger a response in the brain that can have damaging long-term effects on basic brain functions.

Studies in the past have already shown that small particles of soot in diesel exhaust can travel from the nose and lodge in the brain, but this is the first time researchers have found actual adverse effects on brain activity.
“We can only speculate what these effects may mean for the chronic exposure to air pollution encountered in busy cities where the levels of such soot particles can be very high,” said Zuyd University researcher Paul Borm in an interview with Reuters. “It is conceivable that the long-term effects of exposure to traffic nanoparticles may interfere with normal brain function and information processing.”
Scientists put ten volunteers in a room filled with exhaust from a diesel engine (comparable with levels of an urban environment) for an hour and found that after just 30 minutes brain wave patterns displayed a ‘stress’ response. To make matters worse, researchers also said the small particles in the exhaust are also linked with respiratory and cardiovascular disease.
This is worrying considering that carmakers around the world are trying to increase the number of diesel models in their fleets, and it will be interesting to see if new emissions regulations will have a genuine effect on air quality in the near future.

thats wy i am against diesels of any kind also hybrid

So breathing diesel soot makes you stupid?

That explains a few things.

Did they repeat the experiment with gasoline exhaust?

It contains nanoparticles and the pollutants of diesel. It just has the advantage of a scrubber system, which ultra low sulfur fuel will allow to be implemented in diesels.

Exactly. That pic is quite misleading. Most of the "dank" is probably the result of dirty coal fired plants and complete lack of burning restrictions etc. Diesel can be much cleaner than most people think. Like anything it just has to be done well and enforced. The other big contributer in the picture I bet is 2 cycle engines. Jakarta has a huge air quality problem that is heavy contributed to by 2 cycle mopeds.

Catalytic converters will fix this. Lead in gasoline was much more harmful: it's why people voted Republican all those years.

am i the only one who's wondering about appropriate experimental design?!

Yes, the rest of us have inhaled too much diesel soot to respond.

I think it's called "huffing".

Paint is bad, too.
