title: [THE LEVEL OF BENZ(A)PIREN IN TOBACCO SMOKE].
abstract: The medical problems of the environmental pollution with products of tobacco smoke are relatively known. The question of separate components of tobacco smoke, factors such a puff-volume, rate, distance, frequency, length of butt in the environment air is not well understand and should further be investigated. It is shown the dependence of the process on the following factors: physic-chemical parameters of atmospheric environment, brand of tobacco product, activity of smoking process. We aimed to determine the dependence of benz(a)pirene in the air samples of tobacco smoke in the distance of 2,0; 4,0 and 6,0m. from lighting cigarette after puff-by puff. Cigarettes were machine-smoked and the total particulate matter was collected (1,0m3) in room, having no air filtration and substances were analysed and identified by gashromatography. The condacted quantitative and qualitative analyses show, that distance of exposition from burning cigarette can change the volume of benz(a)pirene. In the result of pyrolitic and photochemical reactions in tobacco smoke at certain air space temperature new structures can be formed with high toxity and cancerogenity. The dominant transformation process is reaction with photochemically-produced radicals, which produced benz(a)piren as a minor product. Additional factors effecting indoor concentrations include location and ventilation condition time. Ultrafine particle and benz(a)piren deposition and smoking behavior were observed. The mainstream smoke was also monitored continuously in real time (3, 5 and 10 minute) on a puff-by-puff. Our data show that smoking pastime can change the structure and volume of component of tobacco smoke. The level of benz(a)piren in air samples was evaluated as the main background index of cigarette smoke toxity in relatively small room, having no air filtration system. This question still needs to be explained. It would be interesting to investigate of tobacco smoke components in lung tissue after the smoking process. The studies are necessary in different derection.
