Third-hand smoke may be more frightening than second-hand smoke because third-hand smoke pollution is more hidden, indefensible, and the pollution lasts longer. Components left over from third-hand smoke may combine with surface objects such as furniture or components in the air to undergo chemical reactions to form new toxic substances.
1. Cigarettes contain tar, nicotine, nitrosamines and other components are carcinogens, first-hand smoke is the smoker’s active inhalation of smoke, second-hand smoke is also called environmental tobacco smoke, is passive smoking. Third-hand smoke is not as harmful as first-hand smoke and second-hand smoke, but it lasts a long time, is covert and has a wide range of adhesion, and the compounds in third-hand smoke may react with nitrites in the air to form new and more toxic substances.
2. People through contact with third-hand smoke contaminated furniture, sofas, door handles, walls, carpets, etc. can cause residues of pollution damage, and can even be attached to the skin, hair, clothing.
When coming home from outside, it is recommended to take a shower first, change clean clothes and strengthen indoor ventilation, which can usually reduce the harm of third-hand smoke more effectively.
