The Reduction Effects of Tar, Nicotine, CO andNO₂ by Jade Filter Pipe

&nbsp;&nbsp;It is known that tobacco generates about 4,000 kinds of toxic materials through the reaction of thermal decomposition, thermal composition, distillation, oxidation, hydration and dehydration when it is combusted. Among them such chemicals as tar, nicotine, carbon-monoxide, nitrogen-dioxide are especially noted as major hazardous materials. This study was conducted to examine if jade filter pipe reduce the amount of various hazardous material and found out that it could reduce about 10% of harmful materials in average.<BR>&nbsp;&nbsp;The results obtained were as follows.<BR>&nbsp;&nbsp;There was no great difference in reduction rate of hazardous material by jade filter pipe between high nicotine level tobacco (American) and low nicotine level tobacco (Korean).<BR>&nbsp;&nbsp;The reduction rate of tar, was 16.56% in American tobacco and 12.92% in Korean tobacco. Nicotine was removed by 15.00% and 15.88% in American and Korean tobacco respectively. Carbon monoxide was removed by 4.60% and 5.33% in American and Korean tobacco respectively. Nitrogen dioxide was removed by 10.94% and 10.91% in American and Korean tobacco respectively.<BR>&nbsp;&nbsp;The reduction effectiveness of repeated using jade filter pipe was no significant difference of reduction rate of tar and nicotine. Jade filter pipe could reduced total contents of toxic materials generated from tobacco about 4.6~16.5%.
