Resumo


The present paper evaluated the toxicity of effluent released into the Tiete River, in Barra Bonita City, São Paulo State, using the test micronucleus with Tradescantia pallida. Young inflorescences of T. pallida (n = 20) were partially immersed in one of three treatments: water containing effluent, a positive control (0.1% formaldehyde), and a negative control (distilled water). The results showed a statistically significant difference (p < 0.05) between groups, indicating the genotoxicity of the effluent.
