Please use this identifier to cite or link to this item: In lower concentrations we could observe a high non-linear risk of leukemia, probably due to a greater benzene metabolism and a higher production of its toxic metabolites.
Single-cell gel electrophoresis combined with lesion-specific enzymes to measure oxidative damage to DNA.
Data obtained with both methods were compared and reproducibility of the methylation-sensitive modified version of the comet assay determined. Human biomonitoring ; Biomarkers of exposure ; Environment-wide association studies Source: Throughout the years, this biomarker has undergone several adaptations in their protocol in order to increase its sensitivity and the possible outcomes. Monitoring of gas station attendants exposure to benzene, toluene, xylene BTX using three-color chromosome painting.

Biomarkers of exposure ; Biomonitoring equivalents ; Environment-wide association studies Source: Results obtained contribute to knowledge on the feasibility of this version of the comet assay and its possible usage in human biomonitoring studies as an epigenetic biomarker. By including an additional step of DNA digestion with lesion-specific endonucleases, the comet assay can provide information regarding the type of DNA damage detected in cells.

Until now the influence of risk factors resulting from exposure to biological agents in indoor air has been far less studied than outdoor pollution; therefore the uncertainty of health risks, and how to effectively prevent these, remains.
Air samples were collected in 68 homes, 9 child day-care centres, 20 primary schools and 22 elderly care centres, in a total of rooms with a microbiological air sampler and using tryptic soy agar and malt extract agar culture media for bacteria and fungi growth, respectively.
