Exactly which diesel pollution element causes this effect is still unclear, though, but studies in rats revealed minuscule soot particles making their way, via nasal nerves, directly to the brain

Toxicity of Traffic Proven


In a long overdue announcement, the British Medical Journal stated that breathing in large amounts of traffic fumes can trigger heart attacks, up to six hours later, research reaffirming pollution health risks revealed. A study discovered that high levels of pollution can increase cardiac problem risks, identifying pollutant particle and nitrogen dioxide exposure, via exhaust fumes, as the main culprits in this medical drama

While the authors concede the risk to be small, breathing in enough of those two substances can accelerate an impending heart attack, in an effect called short-term displacement. A London School of Hygiene and Tropical Medicine team, led by Krishnan Bhaskaran examined 79,288 heart attacks over 15 urban areas of England and Wales between 2003-06.
The data was procured from the Myocardial Ischaemia National Audit Project. after which the team examined pollution levels in those areas when patients suffered heart attack, with UK National Air Quality Archive data, studying levels of carbon monoxide, sulphur dioxide and ozone as well as pollutant particles. Environmental group Client Earth is taking the UK government to court for not protecting people's health from pollution in towns and cities, environment secretary Caroline Spelman likely to face a judicial review in late 2011.
29,000 premature deaths a year in the UK are\ attributed to pollution, 4,200 in London alone ,so bold action to cut air pollution, in order to comply with EU limits appears to be essential. especially as pollution can have a major effect on your heart health, thickening the blood to, put you at higher risk of a heart attack.
Not only do you face that risk, but it seems that 30minutes sniffing diesel fumes, on any busy street induces stress responses in the brain, according to research by other scientists, researchers speculating that the brain changes might trigger other responses, such as oxygen deprivation in the heart when subjected\ to diesel fumes.
10 volunteers were exposed to Volvo car exhaust fumes at levels typical of those found on a busy city street, staying in the room for an hour, during which brains were scanned using quantitative electroencephalography, and again after the exposure, results clearly indicating an increase in cortical brain activity after 30 minutes of diesel fume exposure.
Exactly which diesel pollution element causes this effect is still unclear, though, but studies in rats revealed minuscule soot particles making their way, via nasal nerves, directly to the brain, meaning that the long-term effects of exposure to traffic nano-particles could conceivably be interference with normal brain function. though further studies will be necessary.

I knew I hated cities for a reason. Thanks, Tony.
