Lg. Dubinina, MUTAGENIC ACTIVITY OF SEDIMENTS FROM THE RIVER BOTTOM OF NATURAL AND ARTIFICIAL WATER BODIES IN ASTRAKHANSKAYA OBLAST, Genetika, 32(4), 1996, pp. 584-589
Water and organic extracts (WE and OE, respectively) of environment po
llutants were obtained from sediments from the river bottom in order t
o isolate and concentrate environmental mutagens soluble in water and
in organic solvents (dimethyl sulfoxide), Air-dried seeds and sproutin
gs of Crepis capillaris were treated with WE and OE. In other experime
nts, the seeds and sproutings were treated with native silty sediments
, Environmental mutagens from silty sediments and in native silt (with
out extraction) contained in WE consistently induced chromosomal aberr
ations.
