New direct contact approach to evaluate soil genotoxicity using the Vicia faba micronucleus test. [PDF]

open access: yes, 2009
A method to assess micronucleus (MN) induction in Vicia faba roots by direct contact exposure to a solid matrix was developed. The procedure comprised a 5-d germination period, as in the well-known method using aqueous extracts.
