Genotoxicity and phytotoxicity comparison of cigarette butt with cigarette ash.

Genotoxicity and phytotoxicity comparison of cigarette butt with cigarette ash. Environ Sci Pollut Res Int. 2020 Jul 14;: Authors: Mansouri N, Etebari M, Ebrahimi A, Ebrahimpour K, Rahimi B, Hassanzadeh A Abstract The damage potential of cigarette butt and cigarette ash was determined and compared using genotoxicity and phytotoxicity assessments. The concentrations of five heavy metals, As, Cr, Cd, Pb, and Ni, were determined in both cigarette butt and ash leachates to find out if the results of heavy metals are in parallel with toxicity findings. Cigarette ashes and cigarette butts were soaked in distilled water for 7 days. Six leachate butt concentrations, including 200, 100, 50, 25, 12.5, and 6.25 piece/L, were examined. HUVEC cells (human umbilical vein endothelial cells) were exposed to these dilution series for genotoxicity, and Vicia faba seeds were exposed to the same dilution series for phytotoxicity assessments. Three parameters of genotoxicity, including tail length, %DNA in tail, and tail moment, were obtained by the comet assay method, and three parameters of phytotoxicity, including germination rate, root length, and water content percentage, were employed. The results showed that cigarette ash at the concentrations of 50, 25, 12.5, and 6.25 pc/L brings about DNA damage. Meanwhile, cigarette butt causes DNA damage at the concentrations of 100, 50, 25, and 12.5 pc/L. The highest concentrations (200 pc/L for cigarette...
