Cigarillos v Cigarettes In Vitro Data
<p><span>There has been limited toxicity testing of cigarillos, including comparison to cigarettes. The present study compared the smoke chemistry and the cytotoxic and genotoxic potential of ten conventional cigarettes and ten cigarillos based on the greatest market share. Whole smoke and total particulate matter (TPM) were generated using the Canadian Intense (CI) and International Organization for Standardization (ISO) puffing protocols. Tobacco specific nitrosamines (TSNAs), carbonyls, and polycyclic aromatic hydrocarbons (PAHs) were measured using <a name="_Hlk2839899">GC-MS</a>. TPM smoke extracts were used for the in vitro assays. Cytotoxicity was assessed in HBEC4 cells using the neutral red uptake assay. Genotoxic potential was assessed using the micronucleus (MN; A549 cells), Ames, and thymidine kinase (TK) assays. TPM from all cigarillos tested was more cytotoxic than cigarettes. MN formation was significantly greater for cigarillos compared to cigarettes at the highest dose of TPM, with or without rat liver S9 fraction. In the Ames test +S9, both tobacco products exhibited significant dose-dependent increases in mutation frequency (MF), indicating metabolic activation is required for genotoxicity. In the TK assay +S9, cigarillos showed a significantly enhanced MF although both tobacco products were positive. The levels of all measured PAHs, TSNAs, and carbonyls (except acrolein) were significantly greater in cigarillos than cigarettes. The CI puffing protocol demonstrated increased smoke constituent levels compared to ISO. Even though the gas vapor phase was not tested, the results of this study showed that under the tested conditions the investigated cigarillos showed greater toxicity than comparator cigarettes.</span></p>
Data from: There is no such thing as a free cigarette: lining nests with discarded butts brings short-term benefits, but causes toxic damage
Adaptation to human-modified environments such as cities is poised to be a major component of natural history in the foreseeable future. Birds have been shown to adapt their vocalizations, use of nesting places and activity rhythms to the urban environments, and we have previously reported that some species, including the house finch (Carpodacus mexicanus), use cellulose from smoked cigarette butts as lining material and thus reduce the number of ectoparasites in their nests, probably because the nicotine repels arthropods. Nicotine is only one of hundreds of potentially harmful substances found in cigarette butts. Here, we investigated whether the presence of such chemicals is harmful for house finches adding cigarette butts to their nests. We found that hatching and fledging success and chick immune response were all positively correlated to the proportion of the nest that was made up of butts. However, the signs of genotoxicity in the blood cells also increased with the proportion of butt cellulose in the nests. Although we have not measured the effect of genotoxicity on post-fledging survival and breeding success, it seems that bringing cigarette butts to the nest has negative consequences that may counterbalance the benefits of using them as ectoparasites repellents.
Data from: An experimental demonstration that house finches add cigarette butts in response to ectoparasites
Urban species encounter resources that are uncommon in nature, such as materials found in city waste. Many studies have shown that these can be harmful to wildlife. In Mexico City, house finches bring cigarette butts to their nests, which reduces the amount of ectoparasites, but also induces genotoxic damage in chicks and parents. Yet, the reason for this behaviour is unknown. One possibility is that birds extract the cellulose fibres from discarded butts simply because they resemble feathers. Alternatively, disassembled cigarette butts may be brought to the nests because they repel ectoparasites. Here we tested the latter hypothesis by assessing whether house finches Carpodacus mexicanus increase the amount of cigarette butts in their nests in response to a raise in ectoparasite load. When present, fibres from butts are concentrated in the nest lining. By taking it away, we simultaneously removed most of the butt material and collected the bulk of the tick population infesting each nest, as these parasites cluster in the lining. We removed the bedding of nests when chicks had recently hatched, and randomly assigned each nests to one of the following treatments: 1) addition of live ticks, 2) addition of dead ticks and 3) simulation of tick addition. Females in the live ticks' treatment added more butt fibres to their nests than parents in control treatments. Additionally, the amount of butt fibres in the original lining also predicted the amount of fibres added after the manipulation. It seems that the tendency to bring to the nest cigarette butts is at least partially a response to current, and perhaps also past, parasite load.
