Dangerous toxic in cigarette smoke

Heavy metals such as arsenic, cadmium and lead were detected in sidestream cigarette smoke, indicating that these toxic elements can travel different distances in air circulation.

Smoking cigarettes produced more than 4000 chemicals, many are toxic and about 40 cause cancer. These compounds remain in the air as environmental tobacco smoke, which is inhaled by others in the region. There are two main types of tobacco smoke: mainstream smoke that is exhaled by a smoker and secondary smoke from the burning tip of cigarettes.
While investigating heavy metals in sidestream cigarette smoke, researchers from tobacco company Philip Morris USA, has been an accumulation of arsenic in the fireplace used in the first stage of their equipment collection. This phenomenon was not observed for cadmium or lead. They think the reason is that arsenic could be a liquid vapor while cadmium and lead are solid particles.

Michael Chang and his colleagues used a device called a "fish" leader chimney smoke from a cigarette burn to a stream of hits which received as a smoke condensate. The rest of the smoke had escaped capture was whether a mixed cellulose ester filter to try to take rest. Various options were considered for the preparation of the condensed smoke, which in different parts of the equipment. The best sampling method was manure, which involved using the detergent Triton X-100 and nitric acid to make a slurry with the smoke condensate. In inductively coupled mass spectrometry was used for slurry analyzer.

The filing of a greater percentage of the total arsenic (20 percent), as cadmium or lead (less than 5 per cent) in the fireplace shows that toxic elements in cigarette smoke may travel differently in a airflow and can deposit at various points. The researchers believe this behavior is caused by differences between solid (particles) and liquid (steam) phase elements.
