Induction of micronuclei in Vicia faba root tips treated in different soils with the herbicide alachlor.
A study was made of the clastogenic effect of the herbicide alachlor using the micronucleus test on root tips of seeds of Vicia faba that had been placed in 2 soils with different characteristics. No significant increase in micronuclei was observed in the seeds planted in the soil with a high content of organic matter. In those planted in soil with a low content, an increase in micronuclei proportional to dose and exposure time was observed. HPLC analysis of the alachlor residues in the 2 soils showed that they have a different capacity for absorbing the herbicide, which would account for the different genotoxic responses observed.
