OSPAR, Rake and Flood accumulation zone methods were applied at 29 beaches of the German and Lithuanian Baltic Sea coast (2011-2018) to monitor cigarette butt pollution. Also, butt pollution prevention measure - ballot bin, was tested. The number of cigarette butts was significantly higher in Germany than in Lithuania, but the percent of butts from total litter items was similar. Rake method turned out to be suitable for cigarette butt assessment, while the OSPAR method underestimates the butt pollution. The visitor number on the beach had a significant effect on the cigarette butt number: in remote beaches, without visitors, usually, no butts were observed, while the highest number and the percent of butts were observed in beaches with the highest number of visitors. The ballot bin campaign may have increased the public awareness about pollution, but turned out to be in-efficient in reducing it.

Microplastic is one of the most important environmental challenges of recent decades. Although the abundance of microplastics in water sources and water bodies such as the marine were investigated in many studies, knowing the sources of microplastics requires more studies. In this study, litter was investigated as one of the challenges of urban management and the sources of primary microplastic and secondary microplastic in the urban environment.

Background: Illicit cigarette consumption (ICC) results in cheaper cigarettes and lost tax revenue. Although several methods estimate the ICC proportion, the one based on cigarette butt (CB), the most littered item worldwide, is less common. This study aimed at estimating the ICC proportion of Guarujá, a major Brazilian city, based on littered CBs.

Cigarette butts are classified as plastic waste due to their composition of cellulose acetate fibers and are commonly found in beach sand. Their persistence in the environment, low biodegradability, and potential to interact with metals and metalloids during the aging process make them a significant subject of interest for research on coastal marine ecosystems. The aim of this study is to investigate the presence of metals such as hexavalent chromium Cr (VI), cadmium (Cd), and the metalloid arsenic (As) in cigarette butts (CBs), cigarette butt fibers (CBFs), and sand on a tourist beach in Cartagena, Colombia.

Discarded cigarette butts (CBs) are a significant source of environmental pollution. In areas with large amounts of cigarette waste, environmental hazards may arise due to the leaching of chemicals from filters and smoked tobacco. Accurately estimating the number of CBs on beaches requires a standardized method.

Article Synopsis
- Cigarette butts (CBs) are significant pollutants, and this study investigates their effects on Artemia franciscana in different temperature conditions, highlighting the environmental challenges they pose.
- The research included acute and sub-chronic exposure tests to assess toxicity levels of smoked and non-smoked cigarette butts at temperatures of 25°C and 30°C.
- Findings revealed that higher temperatures increased toxicity, disrupting crucial biological functions like enzyme activity and promoting oxidative damage, underscoring the need to address CB pollution in the context of climate change.
