As. Yakovlev et al., Microbial diagnostics of soils polluted by polychlorinated diphenyls and amethod for their detoxification, EURAS SOIL, 33(12), 2000, pp. 1334-1338
The microbial index of soil pollution obtained by the method of enriched mi
crobial cultures characterizes the status of the soils polluted by polychlo
rinated diphenyls. The application of activated humic acids may considerabl
y reduce the content of xenobiotics in strongly polluted soils (with the co
ncentration of diphenyls exceeding the maximum permissible concentration by
60-200 times).
