The Effect of Secondhand Smoke on the Environment

Secondhand smoke comes from exhaled air from cigarette smokers and from the ends of burning cigarettes. According to the Centers for Disease Control and Prevention, more than 50 chemicals in secondhand smoke are carcinogenic.

Ammonia

• Ammonia is present in secondhand smoke. It is highly toxic to aquatic animals, and it is also found in explosives, fertilizers and household cleaners.

Formaldehyde

• Formaldehyde, a carcinogenic chemical, is released into the air from secondhand smoke. Formaldehyde may cause skin, eye or throat irritation and may also trigger severe allergies and asthma.

Arsenic

• Arsenic, used in rat poison, is found in secondhand smoke. Once arsenic enters the atmosphere it cannot be destroyed, meaning the amount of arsenic in our environment can never be reduced. It makes its way into soil, water and air, and when birds and fish ingest enough arsenic it can be fatal.

Carbon Monoxide

• Cars and cigarette smokers emit carbon monoxide into the environment, which can cause flu-like symptoms in humans. At higher doses, exposure can be fatal.

Benzene

• Benzene, found in rubber cement and secondhand smoke, is toxic and extremely flammable. Benzene is more common in indoor air than outdoor air. Its long-term health effects in high exposure include a lowered immune system and white blood cell count, possible bone marrow problems and even leukemia.
