Abstract
Objective: Formic acid is an ubiquitous chemical constituent in the environment, being produced by sources as diverse as vegetation, ants, soil, vehicles, biomass burning, and photochemical reactions. The present work is focused on in vitro analysis of cytotoxic and genotoxic effects of formic acid, using cytogenetic tests such as the cytokinesis-block micronucleus assay (CBMN) and chromosomal aberration analysis, in human lymphocytes. Method: This study was carried out using blood samples from healthy, non-smoking adults aged 18–22 years, of whom 10 were male and 6 were famale. Different concentrations (0.07, 0.1, 0.2, 0.3, 0.4, 0.5, 0.8 mM) of formic acid was added to the lymphocyte culture test for chromosomal aberration (CA) analysis. Mitomycin-C (0.3 mg/ml) was used as the positive control. Human peripheral blood lymphocyte cells were treated with 20, 40, 60, 80 mM concentrations of formic acid for 48 h. for the CBMN test. Mitomycin-C (0.5 mg/ml) was added to the Lymphocyte culture as a positive control. The present research was carried out to assess the cytotoxic and genotoxic effects of formic acid on human peripheral lymphocytes in vitro using the cytokinesis-block micronucleus assay (CBMN), as well as chromosomal aberration (CA) analysis.
