For anyone else who doesn't immediately get the acronym,

"Fine particles (PM2.5) are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope. Fine particles are produced from all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning, and some industrial processes."

While China is somewhat the poster child for modern air pollution, do not overlook that PM2.5 and PM10 exposure is also very bad in many parts of Europe, SE Asia, and large American cities. The Netherlands occasionally experiences a haze that is quite visible and smokey-smelling, in fact tomorrow will be one of the worst days of the year for PM exposure in NW Europe:

The challenge in linking air pollution to age-related disease and mortality risk lies in the confounding correlation with wealth. There are plausible physical mechanisms involving, for example, increased levels of inflammation resulting from high levels of particulate air pollution, but regions with lower levels of air pollution tend to have much wealthier populations, and it is well known that wealth correlates with lower mortality and greater life expectancy, both for individuals and across societies as a whole.

Is there a good website that provides such air pollution current & forecasts for Europe or better world wide?

Is there a way to measure it with a simple and cheap device?

I second this question- please post some links if anyone knows of an effective way to detect and do long-term monitoring of these in-home or at a workplace.
