[Bogotá paint-industry workers exposure to organic solvents and genotoxic effects].

Objective: Investigating the degree of exposure to organic solvents and related genotoxic consequences in paint-factory workers by using cytogenetic monitoring and determining micronuclei frequency in lymphocytes and DNA damage as assessed by comet assays.

Methodology: Excretion of phenol and hippuric and methylhippuric acids in urine was investigated as biomarkers for benzene, toluene and xylene exposure. Urine samples were taken in two paint-factories in Bogotá and in a non-exposed control group.
