Cigarette filters comprise the chemical substances filtered from cigarettes and can leach into waterways and drinking water materials.[168] The toxicity of applied cigarette filters depends on the particular tobacco blend and additives used by the cigarette organizations. After a cigarette is smoked, the filter retains a number of the chemical substances, plus some of These are considered carcinogenic.[45] When finding out the environmental consequences of cigarette filters, the various chemicals that are available in cigarette filters are usually not studied independently, due to the complexity of doing so. Researchers in its place give attention to the whole cigarette filter and its LD50.
Cigareta je cilindrični štapić koji sadrži duvan umotan u tanak papir za pušenje a na jednom kraju filter. Cigareta se zapali na jednom kraju, uzrokujući da tinja; dobijeni dim se udiše oralno preko suprotnog kraja. Pušenje cigareta je najčešći način konzumiranja duvana.

The other process of degradation is photodegradation, which can be any time a molecular bond is damaged via the absorption of photon radiation (i.e. mild). As a result of cellulose acetate carbonyl groups, the molecule Obviously absorbs light at 260 nm,[186] but it includes some impurities which might take in gentle. These impurities are regarded to soak up light-weight during the considerably UV light location (< 280 nm).[187] The environment filters radiation within the Solar and lets radiation of > three hundred nm only to reach the surface. Hence, the main photodegradation of cellulose acetate is considered insignificant to the entire degradation procedure, because cellulose acetate and its impurities absorb light-weight at shorter wavelengths. Exploration is centered on the secondary mechanisms of photodegradation of cellulose acetate to help make up for many of the constraints of biodegradation.
Najnovija verzija plana koji je još uvek podložan promenama – nastoji da se javni prostori očiste od svih aerosola, a ne samo od dima cigareta, odražavajući rastuću zabrinutost u vezi sa zdravstvenim rizicima koje predstavljaju novi duvanski proizvodi, kao što je vaping.
