known as total particulate matter and is inhaled when a cigarette is smoked. Some of the chemicals in tar include benzene and benzo(a)pyrene. Tobacco Smoke Tobacco smoke contains many harmful gases that can be damaging to the body such as carbon monoxide‚ formaldehyde‚ hydrogen cyanide‚ ammonia and acrolein. Passive Smoking Passive smoking is involuntary smoking by non-smokers inhaling the smoke of others. Smoke emitted from a lighted cigarette can be split into two types; mainstream smoke and

The process by which these pollutants harm our bodies begins by simply taking a breath. Particulates are present everywhere‚ in some areas they are as dense as 100‚000 per millilitre of air. There are also other pollutants that you cannot see such as Carbon Monoxide (CO). Carbon Monoxide comes from cars‚ trucks‚ gas furnaces and stoves‚

Chemistry A Bonding Worksheet #1: Introduction to Ionic Bonds The forces that hold matter together are called chemical bonds. There are four major types of bonds. We need to learn in detail about these bonds and how they influence the properties of matter. The four major types of bonds are: I. Ionic Bonds III. Metallic Bonds II. Covalent Bonds IV. Intermolecular (van der Waals) forces Ionic Bonds The ionic bond is formed by the attraction between oppositely charged ions.

So lead recycling can be broadly divided into to two categories * Removal of lead * Pollution control Major pollutants in lead recycling: * Lead * Sulfur dioxide and sulfur trioxides * Carbon monoxide * Nitrogen oxides * Arsenic Impact of lead exposure: Lead poisoning is the most serious environmental health threat to children and one of the most significant contributors to occupational disease. Lead causes symptoms ranging from the

exposure to the hazard? Three potential indoor air quality hazards are: carbon monoxide‚ environmental tobacco smoke‚ and pesticides. Carbon monoxide can come from a number of things. To name a few‚ exhaust from vehicles in garages attached to the house‚ tobacco smoke‚ furnaces‚ gas and water heaters‚ woodstoves and fireplaces‚ as well as gas stoves all have the potential to increase the risk of carbon monoxide pollution in our homes. Environmental tobacco smoke from cigarettes‚ pipes or cigars

* Carbon monoxide‚ hydrogen cyanide‚ and hydrogen sulfide are all examples of chemicals produced in fires that interfere with the use of oxygen by the cell during the production of energy. * If either the delivery of oxygen or the use of oxygen is inhibited‚ cells will die. * Carbon monoxide poisoning has been found to be the leading cause of death in smoke inhalation.
