CIGARETTE



Do you know why cigarette is dangerous for our body?,in this article we can understand about that all.
A cigarette is a small roll of finely cut tobacco leaves wrapped in a cylinder of thin paper for smoking. The cigarette is ignited at one end and allowed to smoulder; its smoke is inhaled from the other end, which is held in or to the mouth and in some cases a cigarette holder may be used as well. Most modern manufactured cigarettes are filtered and include reconstituted tobacco and other additives. Beside that,cigarrete has many completedy of chemistry.they are Nicotine,Tar, Cyanide, Benzene,Cadmium, Hydrogen cyanide, Acetylene,Ammonia,Formaldehyde, Carbon monoxide, Arsenic, Methanol (wood alcohol),and other.it can cause of negatif effect from cigarrete.example is nicotine and cadmium .
Nicotine is a potential neurotoxin and used as raw material for various types of insecticides. At low concentrations, these substances can lead to addiction, especially on cigarettes. Nicotine have limited resources that becomes carcinogenic inhibiting the body's ability to fight cancer cells, but nicotine not cause the development of healthy cells into cancer cells.

Cadmium is one type of heavy metal are dangerous because these elements are at high risk for blood vessels. Cadmium effect on humans for a long time and can accumulate in the body especially the liver and kidneys. Principally at low concentration effect on lung disorders, emphysema and chronic renal disease turbular. The normal amount of cadmium in the soil is below 1 ppm, but the highest rate (1700 ppm) found in surface soil samples taken near the mining ore zinc (Zn). Cadmium is more easily accumulated by the plant compared with other heavy metal ions such as lead. Heavy metals are joined together with lead and mercury as the big three heavy metal that has the highest level of hazard to human health. According to the world body FAO / WHO, consumption per week is tolerated for humans is 400-500 g per person or 7 mg per kg of body weight.
Other than,material of chemistry another also dangerous to our body such us Tar (which consists of more than 4000 chemicals of which 60 of these chemicals are carcinogenic), Cyanide( a chemical compound containing the cyano group Benzene, also known as benzol, organic chemical compounds are flammable and colorless), Methanol(the simplest alcohol, also known as methyl alcohol),Acetylene is an unsaturated chemical compound which is also the simplest alkyne hydrocarbon, Ammonia, can be found everywhere, but is highly toxic in combination with certain elements,Formaldehyde( a highly toxic liquid used to preserve dead bodies), Hydrogen cyanide(a toxin that is used as a fumigant to kill ants. This substance is also used as a maker of plastic substances and pesticides),Arsenic( the material contained in rat poison), Carbon monoxide(a toxic chemical found in car exhaust fumes). So we be carefull with cigarette.
