This chemical substance was tested to determine micronucleus(MN) frequencies in peripheral erythrocytes of the fish Cypnnus c e i o treated in vivo.The concentrations tested were 1.25,2.50,5.00 and 7.50 ppm. Fish were killed after 24 or48 h of treatment. There was a significant increase in the frequency of micronuclei in theanimals treated with 2.50 and 5.00 ppm after 24 h. At higher dosages this effect disappeared probably due to the increased cell lethality. The frequency of MN induction waslower at 48 than at 24 h after treatment. There was a dosedependent increase in MN frequencywhich, however, was significant only at the highest concentration (7.50 ppm)compared to control. 1995 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37011102 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.1 Vol.11 |
