The Polycyclic Aromatic Hydrocarbons, such as naphthalene, are considered priority organic pollutants in environmental studies. Some have high potential for toxicity and can be precursors of mutagenic and carcinogenic effects. The micronucleus test is a sensitive assay to detect aneugenic and clastogenic events caused by xenobiotics. The aim of this study was to assess the mutagenicity of naphthalene after acute exposure in an animal and vegetable model. The sentinels were the fish species Astyanax altiparanae and the plant Tradescantia pallid purpurea. Piscine micronucleus test (fish's erythrocyte) showed no significant difference with the negative control. In the test using pollen mother-cell of Tradescantia the concentration of 0.3 mg L-1 of naphthalene showed a higher micronuclei frequency compared to the negative control. The Trad-MCN demonstrated greater sensitivity for the detection of chromosomal breakage and loss caused by naphthalene.
