MASSACHUSETTS HEALTH OFFICIALS were worried about the effects of breathing second-hand cigarette smoke in stuffy railway cars, so they asked Massachusetts Institute of Technology to investigate. MIT’s conclusions, outlined in a letter from Professor William Ripley Nichols, were unambiguous:
“The products of the tobacco consumed mix with the air and render it oppressive to most nonsmokers…A very little tobacco smoke does indeed affect the eyes and throat of a person unaccustomed to its use, but our senses are often affected by quantities too small to weigh, too small even to detect by chemical means.”
That report was prepared 114 years ago. The only change since then has been a dramatic improvement in the means of measuring the chemical constituents of tobacco smoke and of weighing their deadly effects.
Using techniques that measure down to parts per billion, scientists now know that so-called passive smoke contains carbon monoxide, nitrogen dioxide, polycyclic-aromatic hydrocarbons, nicotine, inhalable particles and hundreds of other dangerous compounds. It also contains about 50 chemicals, such as benzene, which are known or suspected to cause cancer.

And researchers suspect carbon monoxide, ammonia, benzene and other toxins may be present in higher concentrations in passive smoke than in what a smoker inhales, which has been burned at higher temperatures that destroy some of the pollutants. In a 1986 report, Surgeon General C. Everett Koop said there is evidence “sidestream smoke may be more carcinogenic.”

In this place you can learn more information about mitral valve repair and mitral valve surgery that now being the most concern issue.

You can also check out the information about the mitral valve replacement. This procedure can be done only if the condition and requirements are fulfilled. Get information only from the expert and I am sure this place can be the best place for it.

Many self-help and support groups operate toll-free telephone numbers to help you learn more about a medical condition, answer your questions, and help you to locate a local support group. And the good news is that much of the information is free.

Sponsored by a wide variety of organizations, these are some of the most popular health-related toll-free numbers. Some are operated by nonprofit groups; others are not. Some provide only information; others have products or publications to sell. Note that there are three types of numbers listed: national, regional, and state. Many organizations have national toll-free numbers that are accessible from every state, but there are exceptions, such as toll-free numbers limited to specific states or regions. We indicate the exceptions.
Every number listed here was checked to determine if it was operating, which it was as of June 1990. But should you encounter any problem with a number, we suggest that you contact the toll-free directory assistance operator at 800-555-1212.
