Assessment of a possible genotoxic environmental risk in sheep bred on grounds with strongly elevated contents of mercury, arsenic and antimony.
1996
A part of Northern Palatinate country (Germany) was formerly influenced by mercury mining. Today, in many cases agricultural and housing areas are placed onto or near to former dump grounds of rubble. In the soil of these areas the concentration of mercury, arsenic and antimony was found ranging from basic natural contents up to strongly elevated levels. In a biomonitoring project, sheep bred on grounds contaminated with mercury (range 1-435 mg Hg/kg dry matter), arsenic (range 17-147 mg As/kg dry matter) and antimony (range 2-15 mg Sb/kg dry matter) were taken as example on the uptake of these elements from the environment and for possible effects of this exposure. Significantly elevated m…
Genotoxicity of selected pesticides in the mouse bone-marrow micronucleus test and in the sister-chromatid exchange test with human lymphocytes in vi…
1996
Selected pesticides (aldicarb, 1,3-dichloropropene, methidathion, parathion, triadimefon, vinclozolin) were tested for their clastogenic and aneugenic activities in the mouse bone-marrow micronucleus (MN) test in vivo and for their sister-chromatid exchange-inducing activities in human lymphocytes in vitro in the presence and absence of an exogenous metabolizing system from rat-liver S9. 1,3-Dichloropropene significantly increased the frequencies of micronucleated polychromatic erythrocytes (PCE) in bone-marrow cells of female mice from 3.3 MN/1000 PCE to 15.3 MN/1000 PCE (187 mg per kg body weight). 1,3-Dichloropropene (100 microM) induced 16.0 SCE/metaphase after 24 h of incubation as com…
In vivo genotoxicity of selected herbicides in the mouse bone-marrow micronucleus test
1997
The herbicides alachlor, atrazine, terbuthylazine, gluphosinate-ammonium, isoproturon, pendimethaline and trifluralin were tested for genotoxicity in the mouse bone-marrow micronucleus test (MNT). Both atrazine and trifluraline caused a significant increase in the number of micronuclei at doses of 1,400 mg/kg body weight in female mice only. Alachlor, terbuthylazine, gluphosinate-ammonium, isoproturon and pendimethaline did not have any genotoxic effect in the mouse bone-marrow micronucleus test in either female or male animals.
