National Taiwan University, Taipei, Taiwan The explained variance in most models, except those for K and S, was 450%. PM2.5, Cu, Fe, and Zn showed a large spatial variation and were modeled reasonably well.

15. PM2.5 can also cause adverse impacts on respiratory, cardio-cerebral-vascular and nervous system. [3]Professor Pan Xiaochuan in Department of Medicine ， Peking University recorded and watched the change in number of cardio-cerebral-vascular emergency patients in The Third Hospital of Peking University during 2O04-2006 Air Pollution & Cardiovascular Diseases Incident rates of asthma and bronchitis also increased obviously.[3]

21. Will air pollution drive you mad?

22. Outlook Standardizing the monitor of PM2.5 Controlling generation of PM.2.5 Calling for the awareness of self-protection

23. No Lower Limit- BY TRACI WATSON No level of air pollution below which there is no increased risk of developing the disease.
