Article Abstract
Cigarette butts (CB) are a source of microfibers (MFs) in aquatic environments, posing a risk to the health of aquatic organisms. Research has been focused on examining the toxicity of CBs on ecological receptors, including invertebrates. More focus has been on death, growth, or movement inhibition of but less on exoskeletal effects in malacostracans. We evaluated the alteration in the carapace structure of whiteleg shrimp (Penaeus vannamei Boone, 1931) caused by MFs derived from CBs (CB-MF). Exposure to CB-MF damaged the gills, the main organs adsorbing calcium in shrimps to generate a hard carapace, disturbing calcium uptake via respiration. Rapid ecdysis caused on CB-MF exposure reduced the environmental adaptation capacity of crustaceans in the absence of normal pigments in the chromatophore of the carapace. These findings indicate that MFs released from CBs released into the aquatic environment can adversely affect exoskeletal alteration within the overall ecosystem.
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.
Anthropogenic litter is one of the most important factors that influence recreation users and their activities because of its correlation to the river and environmental health. We monitored pollution levels on the Illinois river, near Tahlequah, OK for three months and surveyed the publics opinion on the issue. Our goal was to get this data to local and state management agencies to management practices to keep the scenic Illinois River clean.
* A total of 161,293 litter items were collected, with cigarette butts making up the largest portion at 36.3%, along with significant amounts of metal (16.2%) and glass (13.0%); surprisingly, face masks represented only 0.2% of the waste in 2022.
* The study found no significant correlation between waste levels and city population or density, although a slight trend showed a decrease in plastic bottles over time and identified 19 different polymers, including

Discarded cigarette waste may leach toxic elements and can contaminate different environments. In this study, the levels of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in cigarette butts (CBs) leachates were determined, and the release rate of these pollutants from three CBs types such as smoked CBs with and without tobacco (SCBs and SFs) and unsmoked filters (USFs) were examined. The mean concentration levels of PCBs compounds were View Article and Find Full Text PDF
