Smoker (Ladies & Guys), Beware of Your Lung Due to Cancer

The lead in cigarettes is radioactive. It has a “half-life” of 20 years. This means it continues to be radioactive for a long time. So, if you stop smoking, the risk of cancer continues. On the facing page, there is a photograph of cancer cells.

Smoking is dangerous. That has been proved. Cigarettes cause many lung and throat illnesses, including cancer. Now and Australian scientist has found more proof. He is Professor Harry Bloom, of the University of Tasmania. He has found that tobacco smoke contains radioactive carcenogenes.

A carcenogene is something which cause cancer. Cadmium and lead are both carcenogenes. For years, scientists have known this. They also knew that tobacco contained cadmium and lead. The substances are found in the trichomes, the small hairs on tobacco leaves but there was a problem. Is cadmium and lead inhaled or does it stay in the ash?

Professor Bloom made a new machine. It measures cadmium and lead particles in cigarette smoke. It uses a micro-air sampling pump. This is a special, small pump. It takes small, regular samples of air. Each sample is 35 mll. The machine imitates a man smoking. It takes a 35 mll “puff” for two seconds, once a minute.

The smoke is trapped by paper filters. These absorb the chemicals in the smoke. The chemicals can then be analysed. This is done by a machine called an atomic absorption spectrophotometer. This machine identifies and measures metal in the smokes.

Four Brands of cigarette have been tested. Professor Bloom has also tested a special cigarette. This is a “reference standard” cigarette. It is made by the University of Kentucky U.S.A., to help with cigarette research.

What did Professor Blood find? A lot. The reference cigarette contained 1.28 mg lead and 0.74 mg cadmium in each packet. “These are very high concentrations”, he said.

“A smoker inhales about half the smoke from a cigarette. So, about half of this lead and cadmium will be inhaled. It will stay in the lungs, Also, if one person is smoking, other people in the room will inhale lead and cadmium.”

Tar and nicotine are often thought to cause cancer. Many cigarettes now have filters. These stop some of the tar and nicotine. So some smokers believe they are safe but these filters do not stop lead and cadmium but Professor Bloom says, a lead and cadmium filter is possible. This would make cigarettes much safer, but very expensive.

Professor Bloom became interested in this problem years ago. He had read about some tests. They were blood tests. They compared the blood of smokers and non-smokers. The smokers had much more lead and cadmium in their blood than non-smokers. He wanted to know why. So he started his present research.

The lead in cigarettes is radioactive. It has a “half-life” of 20 years. This means it continues to be radioactive for a long time. So, if you stop smoking, the risk of cancer continues. On the facing page, there is a photograph of cancer cells.
