Formaldehyde (in Cigs)
Formaldehyde is one of the many chemicals present in cigarettes.
Formaldehyde (also known as methanal), is a gas at room temperature and has a strong pungent smell. Its chemical formula is H2CO. It is soluble in water, and it is commonly sold as a 37% solution in water under trade names such as formalin or formol.
Formaldehyde is used a preservative in medical laboratories, as an embalming fluid, and as a sterilizer. Non-medical uses of this chemical include the the production of resins, and as a chemical intermediate.
When present in the air at levels at or above 0.1 ppm, formaldehyde can lead to acute health effects, such as watery eyes; burning sensations in the eyes, nose and throat; nausea; coughing; chest tightness; wheezing; skin rashes; and other irritating effects. Formaldehyde can affect people in various ways. Sensitive people can experience symptoms at levels below 0.1 ppm.
