Genome Response of Model Invertebrates and Vertebrates Species to Stress Agents in the Environment
In both groups of studied species genome instability were found, realized by many structure chromosome rearrangements which can be used as a cost-effective indicator of genotoxicity, and hence suitable markers of potential environmental stress.
Micronucleus Test from Free Living Rodents as a Biomarker for Environmental Stress in Situ
The results obtained demonstrate that the in vivo MN test may be a sensitive end-point for the detection of genotoxity that may result from the simultaneous action of several metals and may be useful as a biomarker of environmental stress in situ.
Assessment of Nuclear Abnormalities in Erythrocytes of Balkan Pond Turtle Mauremys rivulata ( Valenciennes , 1833 ) ( Testudines : Geoemydidae ) from the Biga Stream , Çanakkale , Turkey
Reptilian species are potentially efficient bioindicators of pollution and habitat destruction. Turtles may be especially useful for monitoring the chemical contamination of their habitats. The aim
Assessing effects of chronic heavy metal exposure through a multibiomarker approach: the case of Liomys irroratus (Rodentia: Heteromyidae)
Genetic structure of L. irroratus populations revealed that the main source of genetic variation was located within populations, and multibiomarker studies in environmental settings using sentinel species are valuable for environmental risk assessment and ecological responses in chronic exposed populations.
Small mammals as biomonitors of metal pollution: a case study in Slovenia
The findings indicate that the majority of small mammals trapped in the area of the former lead smelter are at risk of toxic effects due to the very high bioaccumulation of Pb and Cd in the organism and suggests that Apodemus flavicollis and Myodes glareolus are very suitable biomonitors of metal pollution.
Comparative Data of the Chromosome Fragility in Five Wild Small Mammal Species
ABSTRACT Small mammals are widely used as suitable indicators of environmental pollution and genotoxic damage. The present investigation of the karyotype sensitivity to the influence of a strong

Soil ingestion may be a significant route of lead uptake in small mammals at the range and the tendency of lead to concentrate in the bones rather than in more digestible soft tissues may minimize food chain uptake of lead by predators, especially raptors that regurgitate undigestible material.
Cancer risk from inorganics
Views on mechanisms that may be responsible for the carcinogenicity of metals are updated and analysed, and questions are raised as to the effectiveness of conventional dosimetry in accurately measuring risk from radiopharmaccuticals.

Cytogenetic effects in mice after chronic exposure to arsenic followed by a single dose of ethylmethane sulfonate.
The influence of a long-term treatment with arsenic (As2O3 250 mg/l in drinking water for 2-8 weeks) on the frequency of chromosome aberrations induced by a single treatment with ethylmethane
Maternal and fetal chromosomal aberrations in mice following prenatal exposure to subembryotoxic doses of lead nitrate.
Maternal exposure to low levels of lead nitrate, administered on the 9th day of gestation, did not cause embryonic resorption and fetal lethality, but induced chromosomal deletions and other forms of aberrations in fetal liver and maternal bone marrow cells.
