There is no threshold level of fine particle pollution below which health risk reductions are not achieved by reduced exposure.

Air pollution can be a major health threat, especially for at-risk populations and those with respiratory illness. This study will help us target improvements to clean the air, improve the environment and enhance public health.

Current standards do not do enough to protect the public from serious health dangers associated with this form of pollution.

The AP's analysis of health risks posed by industrial pollution across the country is a substantial contribution to the public's understanding of where greater attention needs to be focused.

The reality is that zero defects in products plus zero pollution plus zero risk on the job is equivalent to maximum growth of government plus zero economic growth plus runaway inflation

My health is fine.
