The aim of the present work was to evaluate the potential cyto- and genotoxicity of TBZ in the aquatic macrophyte Bidens laevis, exposed to a range of concentrations of 0.1\u2013100 \u03bcg\/L. Mitosis in root tips were analyzed showing decreased mitotic index and an increase of chromosomal aberrations at 10 and 100 \u03bcg\/L. The regression of TBZ concentration vs. aneugenic aberrations was significant, indicating the mechanism of genotoxicity. The specific growth rate (Gr) for total length decreased in plants exposed to 0.1, 10 and 100 \u03bcg\/L. Gr for root decreased in plants exposed at 0.1 and 10 \u03bcg\/L, reaching a maximum percent inhibition root growth rate (Ir) of 68.8%. These results show that TBZ resulted cyto- and genotoxic to B. laevis at environmentally relevant levels."],"dc:format":["application\/vnd.openxmlformats-officedocument.spreadsheetml.sheet"],"dc:language":["eng"],"dc:type":"dataset","dc:rights":["info:eu-repo\/semantics\/restrictedAccess","Protecci\u00f3n de datos personales (Ley 25.326)"],"dc:relation":["info:eu-repo\/grantAgreement\/Ministerio de Ciencia, Tecnolog\u00eda e Innovaci\u00f3n Productiva.
