Dangerous chemicals in tobacco smoke
The most damaging components of tobacco smoke are:
Tar – The particles
contain chemicals, including several cancer-causing substances (carcinogens).
Tar is sticky and brown, and stains teeth, fingernails and lung tissue. Tar
contains the carcinogen benzo(a)pyrene
Carbon monoxide – this odourless gas is fatal in large doses
because it takes the place of oxygen in the blood. Each red blood cell contains
a protein called haemoglobin that transports oxygen molecules around the body.
However, carbon monoxide binds to haemoglobin better than oxygen because it has
higher affinity compare to oxygen. This means that less oxygen reaches the
brain, heart, muscles and other organs
Free radicals – these highly reactive chemicals can damage
the heart muscles and blood vessels. They react with cholesterol, leading to
the build-up of fatty material on artery walls. Their actions lead to formation
of atherosclerosis that can effect heray, brain kidney and lower legs.
Metals – tobacco smoke contains dangerous metals including
arsenic, cadmium and lead. Several of these metals are carcinogenic and toxic
to internal organ for example ti liver and pancreas.
