The opposite means of degradation is photodegradation, that is each time a molecular bond is damaged by the absorption of photon radiation (i.e. light). As a consequence of cellulose acetate carbonyl groups, the molecule By natural means absorbs gentle at 260 nm,[186] nevertheless it includes some impurities which often can take up light. These impurities are recognized to absorb mild inside the far UV light region (< 280 nm).[187] The ambiance filters radiation within the sun and allows radiation of > 300 nm only to reach the area. Hence, the principal photodegradation of cellulose acetate is taken into account insignificant to the whole degradation method, considering the fact that cellulose acetate and its impurities absorb light-weight at shorter wavelengths. Investigation is centered on the secondary mechanisms of photodegradation of cellulose acetate to help make up for a few of the restrictions of biodegradation.

Cigarettes include numerous chemical additives to preserve flavor and increase nicotine absorption. Numerous of these chemical substances could cause cancer.
