Abstract in Portuguese
O objetivo deste estudo foi aumentar o banco de dados em relação a resíduos (cake) e efluentes (licor) industriais e o seu nível de clastogenicidade. Este estudo contribuiu para mostrar: a) que o bioensaio com Tradescantia pallida foi sensível para a avaliação da clastogenicidade em mistura complexa de resíduos catalíticos industriais, nunca testados anteriormente. b) a tendência de uma dose resposta para ambos os resíduos catalíticos c)a pasta (cake) apresenta maior clastogenicidade que o licor nas concentrações estudadas. Provavelmente isto se deve a menor concentração de Ti e Al no licor do que no cake.

Abstract in English
The aim of this study was to increase data concerning liquid effluent (liquor) and solid waste (cake) and their level of clastogenicity using TradMCN. This study contributed to show a) bioassay Trad-MCN with Tradescantia pallida was sensitive to evaluate the clastogenicity in a complex waste mixture, never tested before b) a tendency of a dose response for both catalytic wastes. c) higher clastogenicity of cake comparing to liquor effluent in concentrations evaluated. Probably this is due to the much lower Ti and Al concentrations in the liquor than in the cake
