“…Metals vary in leaching rates, with some (e.g., Pb, Ni, Zn) leaching primarily during the first day and others (e.g., Fe, Mn) continuing to leach over a 34-day period (Moerman and Potts 2011). This rapid leaching of CBs is reflected in the frequent use of a 24-h leaching period to produce effluent for toxicity tests (e.g., Micevska et al 2006;Lee and Lee, 2015;Cardoso, 2018;Micevska et al 2006;Osuala et al 2017;Slaughter et al 2011;Wright et al 2015;this study).…”

Cigarette butt effects on diatom health in a stream ecosystem

Cigarette butts are a prevalent form of litter containing numerous toxic chemicals. Because cigarette butts are frequently deposited on the ground and carried into water bodies, greater understanding of the toxic effects of cigarette butts in aquatic ecosystems is needed. We examined the toxicity of cigarette butts to algal growth and diatom health-especially pertinent because of the strong ecological role of these organisms. We modified the agar-based nutrientdiffusing substrate method by using cigarette butt leachate (at 10, 5, 2.5, and 1.25 butts/l concentrations), a whole cigarette butt, and a plain agar control. After incubating for 10 days in a small stream, the biofilms from the diffusing substrates were assessed for algal biomass and diatom health (chloroplast intactness and size of lipid bodies in two abundant species of Navicula). There were no significant differences among the cigarette butt treatments for algal biomass or diatom health; hence, evidence of toxic effects was not found. Other studies have demonstrated cigarette butt leachate toxicity to fish and aquatic invertebrates, but these studies were done in closed systems. In contrast, in open stream ecosystems, effluent may be quickly diluted and carried away by water flow, and the complex chemical environment of streams likely includes leachate from a variety of riparian leaves that fell into the stream (i.e., algae are naturally exposed to low concentrations of a wide variety of secondary chemicals). Our results do not preclude the finding of toxicity of cigarette butt effluent to algae, including diatoms, in standard toxicity tests.

“…To make cigarette butt effluent, 10 cigarette butts were soaked in 1 L of deionized water for 24 h (Osuala et al 2017), producing an effluent 10 times the lethal concentration for two tested fishes (Slaughter et al 2011). This water was used as the full concentration effluent in making the agar gels.…”

Recent studies have shown that cigarette consumption affects much more than human health. Smoked cigarette butt (SCB) disposal into the environment can bring little-known negative biological consequences to mammals, since it contains many organic and inorganic toxic chemical constituents. Thus, we aim at assessing whether the ingestion of water with leached SCB for 60 days by female Swiss mice changes their defensive behavioral response to potential predators (cats and snakes). We worked with the following groups of animals: control (pollutant-free water), water with environmental concentration of SCB (1.9 μg/L of nicotine), and concentration 1000 times higher (EC1000×). Our data show that the treatments did not cause locomotor, visual, auditory, and olfactory deficit in the animals. However, we observed that the animals exposed to the pollutants did not present behavioral differences in the test session with or without the snake. On the other hand, animals in all groups showed defensive behavior when the test was conducted with the cat in the apparatus. However, female mice presented weaker response than the control. Thus, our data point towards the potential neurotoxic damage caused to mice who have ingested water with SCB residues, even at low concentrations.
