Beijing 2008: scientists predict circulation problems

Being held in one of the most polluted cities on the planet, this year's Olympics gives us a unique glimpse into just how unchecked pollution can impact human life. From water concerns, to air quality issues, and even algae infestations -- the Beijing games have already generated loads of ecological news. Now, scientists in Hong Kong are warning that particulates in Beijing's air may cause Olympians some serious blood circulation issues.

Their logic is simple: athletes consume more oxygen, and therefore absorb more particulate matter through their respiratory system -- and on into their bloodstreams. The buildup of these particulates causes inflammation in the respiratory system and the increases the viscosity of blood -- seriously altering an athlete's circulation. Not only will can these conditions hurt their cardiovascular performance, scientists say, but it has the potential to hospitalize the Olympians that are most susceptible.
