Summary

Researchers exposed aquatic invertebrates (rotifer Brachionus calyciflorus, water flea Daphnia magna) and terrestrial invertebrates (woodlice Porcellio scaber, mealworm Tenebrio molitor) to microplastics derived from both unsmoked and smoked cigarette filters at concentrations ranging from 1 to 100 mg/L and assessed acute toxicity. The study found that cigarette butt-derived microplastics caused measurable adverse effects on multiple invertebrate species across both aquatic and terrestrial exposure routes.

Cigarette butts are one of the most important sources of microplastics (MPs), due to their global occurrence and the significant amounts found in the environment. The aim of this study was to investigate the effects of MPs produced from unsmoked (UCF-MPs; fragments, number mean size ± SD: 12.71 ± 6.82 µm) and smoked cigarette filters (SCF-MPs; fragments, 9.06 ± 4.1 µm) on aquatic (rotifer Brachionus calyciflorus, water flea Daphnia magna) and terrestrial invertebrates (woodlice Porcellio scaber, mealworm Tenebrio molitor). Aquatic organisms were exposed to MPs in a concentration range of 1–100 mg/L in water media for 24 h and 48 h for B. calyciflorus and D. magna, respectively. On the other hand, terrestrial organisms were exposed to MPs in a concentration range of 0.06–1.5 Also see: https://micro2024.sciencesconf.org/558756/document
