Hi all,
I would be very glad if someone could suggest a relatively simple and quick 
method (quantitative or semi-quantitative) to determine microbial activity 
in soils contaminated with heavy metals and phenol. Unfortunately the 
Tetrazolium salt Method does not work for me since most of the heavy metals 
as well as nitrate also compete for electrons and thus reduce the colour 
Many thanks for any contribution,
Dorothea Smith
