ClearA review on cigarette butts: Environmental abundance, characterization, and toxic pollutants released into water from cigarette butts
This review examines the environmental impact of discarded cigarette butts, which number in the trillions worldwide each year and are among the most common litter items. Researchers found that cigarette filters release harmful substances including heavy metals, nicotine, and cellulose acetate microplastic fibers when they enter water. The study highlights that cigarette butt pollution represents a significant but often overlooked source of both chemical contamination and microplastic pollution in aquatic environments.
A Review of Environmental Pollution from the Use and Disposal of Cigarettes and Electronic Cigarettes: Contaminants, Sources, and Impacts
Researchers reviewed the environmental pollution caused by the use and disposal of cigarettes and electronic cigarettes, including their role as a source of microplastic contamination. Cigarette butts made of cellulose acetate are minimally degradable and represent a major source of both bulk plastic and microplastic pollution, particularly in aquatic ecosystems. The study documents that cigarette butt leachate and nicotine are toxic to a wide range of organisms from microbes to mammals.
Cigarette filters as a major source of microfibers in aquatic environments.
This study found that discarded cigarette butts persistently release cellulose acetate microfibers into aquatic environments, identifying cigarette filters as a major and underappreciated source of microfiber pollution. The research quantified microfiber release rates under simulated environmental conditions.
Different faces of cigarette butts, the most abundant beach litter worldwide.
Cigarette butts collected from an urban beach were characterized at different stages of physical and chemical degradation, revealing they shed cellulose acetate microplastic fibers and leach toxic chemicals as they break down. As the most abundant beach litter worldwide, cigarette butts represent a significant but often overlooked source of plastic fibers and chemical contamination in marine environments.
Smoked cigarette butts: Unignorable source for environmental microplastic fibers
Researchers highlight that discarded cigarette butts, made of cellulose acetate plastic, are an overlooked but major source of environmental microplastic fibers, with each butt containing over 15,000 detachable plastic strands. They estimate that approximately 300,000 tons of potential microplastic fibers from cigarette butts may enter aquatic environments annually. The study notes that these fibers also carry toxic substances like nicotine and carcinogenic compounds that can harm aquatic organisms.
Tiny but Deadly: a Threat to Environment
This study quantified toxic metals leaching from discarded cigarette butts — the most common form of plastic litter — finding that both the filter and the whole butt release metals into water. Cigarette filters are made from cellulose acetate plastic and represent a poorly recognized source of chemical pollution in the environment.
Cigarette butts as a microfiber source with a microplastic level of concern
Researchers investigated whether cigarette butts are a significant source of microfiber pollution by analyzing smoked and unsmoked filters. They found that cigarette filters release large quantities of cellulose acetate microfibers, with smoked filters releasing even more than unsmoked ones due to degradation during use. The study identifies discarded cigarette butts as an overlooked but substantial contributor to microplastic pollution in the environment.
Microplastic fibers and leachates from cigarette butts: environmental impacts, toxicological concerns, and circular economy-driven solutions
This review of existing research shows that cigarette butts are the world's most common plastic trash, slowly breaking down into tiny plastic fibers that spread harmful chemicals like nicotine and heavy metals into water and soil. These microplastics hurt fish and other animals by changing their behavior and building up in their bodies, which could affect the entire food chain. Since humans eat fish and use water from these contaminated environments, cigarette butt pollution may pose health risks that need more research and better cleanup solutions.
Quantitative assessment and spatial distribution of macroplastic and cigarette butt contamination in Bushehr's stormwater system near the sensitive Persian Gulf coast
This study assessed the abundance and spatial distribution of macroplastics and cigarette butts across multiple sites, quantifying their contribution to environmental microplastic pollution as cellulose acetate filters degrade. Cigarette butts emerged as a significant and underappreciated source of plastic contamination in terrestrial and aquatic environments.
Microplastics from cigarette filters: Comparative effects on selected terrestrial and aquatic invertebrates
Researchers compared the effects of microplastics from smoked and unsmoked cigarette filters on both land and water invertebrates. Smoked filter microplastics were more toxic due to the added chemicals from tobacco smoke, causing reduced survival and reproduction in the test organisms. Since cigarette butts are one of the most littered items worldwide, this study shows they are a significant and underappreciated source of toxic microplastic pollution in the environment.
Research on the presence of cigarette butts and their leaching of chemical pollutants and microparticles: the case of Dalian, China
This study quantified toxic substances (heavy metals, PAHs, and microplastics) leached from littered cigarette butts from major Chinese brands, providing data on the pollution contribution of cigarette butt litter in urban Chinese environments.
The unignorable ecological impact of cigarette butts in the ocean: an underestimated and under-researched concern
This opinion piece argues that cigarette butts — which contain plastic cellulose acetate filters that fragment into microplastics — are a significantly underestimated source of ocean plastic pollution. Billions of cigarette butts are discarded each year, and recognizing them as a major microplastic source is important for designing more effective litter-reduction policies.
The impacts of littered cigarette butts on the common periwinkle (Littorina littorea)
This study assessed how littered cigarette butts, estimated at 4.5 trillion discarded annually, affect the common periwinkle snail after entering waterways, where cellulose acetate filters leach toxic chemicals. Cigarette butt exposure caused measurable harm to periwinkles, demonstrating that this overlooked litter type poses a genuine ecotoxicological risk.
A review of occurrence and concentrations of cellulose acetate and other artificial cellulose microfibers in aquatic environmental matrices: an indicator of cigarette butts’ contamination?
This review examines the occurrence of cellulose acetate microfibers in aquatic environments, primarily originating from discarded cigarette butts, which are among the most littered items worldwide. The authors found that cellulose acetate is one of the most frequently detected microfiber types in water, sediment, and marine organisms, with higher accumulations in sediment and bottom-dwelling animals. The study suggests that cellulose acetate levels could serve as an indicator of cigarette butt contamination in the environment.
A preliminary investigation of associated chemicals in cigarette butt waste from the tourist beach area of North Jakarta, Indonesia
Cigarette butts collected from a tourist beach in North Jakarta were found to contain a complex mixture of aliphatic and aromatic chemicals, despite the beach receiving regular cleaning. Because cigarette filters are made of cellulose acetate — a persistent plastic-like material — this study highlights that cigarette butt litter is both a significant form of beach plastic pollution and a chemical contamination source in coastal environments.
Fate of nanoplastics in the environment: Implication of the cigarette butts
This study investigated cigarette butts as an underrecognized source of nanoplastic pollution, finding that cellulose acetate filters can fragment into nanoscale particles that disperse in the environment. Given the enormous volume of cigarette litter worldwide, butts may represent a significant and overlooked nanoplastic pathway.
Global cigarette butt contamination: a review
This review of 130 studies found that cigarette butts are everywhere in our environment—averaging about 1 butt for every 4 square meters globally—and they're especially common on beaches and in water where people swim and fish. These toxic cigarette filters break down into harmful chemicals and microplastics that can contaminate our water and food supply. The good news is that well-protected areas like national parks have nearly 10 times fewer cigarette butts, showing that proper management can reduce this health threat.
