Pollution and blood clots

Particles may pose risk at levels present in many U.S. cities

Air pollution dramatically boosts an individual’s risk of developing deep vein thrombosis, a new study indicates. People with DVT typically develop clots in the leg or thigh. If those clots break off and travel, especially to the lungs, organ damage or death may follow.

CLEAR SKY? Because air pollution particles that fall into the PM10 range are too small to see with the naked eye, an apparently clear sky could host toxic concentrations of them.
