     Carbon monoxide poisoning (一氧化碳中毒) causes death and injuries around the world. This gas is a

problem in all parts of the world that experience cold weather. A few years ago, America's Centers for Disease

Control (C. D. C. ) studied deaths linked to carbon monoxide poisoning. It found that the average number of

carbon monoxide deaths in the United States was greatest in January. The C. D. C. also found that carbon

monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people

are taken to hospital emergency rooms for treatment of health problems linked to the gas.

     Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color,

no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon

monoxide gas is very deadly. It steals the body's ability to use oxygen.

     Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking

with the blood. When the gas links with the blood, the blood is no longer 1able to carry oxygen to the tissues

that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide.

     How quickly this can happen depends on the length of time a person is breathing the gas and the amount of

the gas he or she breathes in.

     Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small

amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The victim's stomach

may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.

     People develop severe head pain as the amount of the gas continues to enter their blood. They will begin to

feel very tired and sleepy. They may have terrible stomach pains.

     Medical experts say carbon monoxide affects people differently. For example a small child will experience

health problems or die much sooner than an adult. The general health of the person or his or her age can also

be important.
