Abstract

This study examines occupational exposure to perchloroethylene among dry cleaning workers in Bogotá, Colombia, where its use remains prevalent despite global trends toward alternatives. A cross-sectional analysis was conducted with 9 workers to measure perchloroethylene exposure levels and blood concentrations. Additionally, a case-control study assessed gamma glutamyl transferase (GGT) and alanine aminotransferase (ALT) as biomarkers for hepatocellular damage. Workers were classified into 3 job categories: dry cleaning operators, ironers, and cold washing operators. Results indicated that dry cleaning operators experienced significantly higher exposure levels (0.72 to 7.22 ppm) compared to ironers and cold washers (0.001 to 3.39 ppm). All exposure levels were below the adjusted threshold limit of 19.58 ppm, and blood perchloroethylene concentrations were below detection limits. No significant differences in GGT and ALT levels were observed between exposed workers and the control group. Given the small sample size, further research is warranted to better understand exposure risks in this sector. Emphasizing a culture of prevention is crucial due to the carcinogenic potential of perchloroethylene, even at low environmental exposure levels.

期刊介绍： About the Journal Annals of Work Exposures and Health is dedicated to presenting advances in exposure science supporting the recognition, quantification, and control of exposures at work, and epidemiological studies on their effects on human health and well-being. A key question we apply to submission is, "Is this paper going to help readers better understand, quantify, and control conditions at work that adversely or positively affect health and well-being?" We are interested in high quality scientific research addressing: the quantification of work exposures, including chemical, biological, physical, biomechanical, and psychosocial, and the elements of work organization giving rise to such exposures; the relationship between these exposures and the acute and chronic health consequences for those exposed and their families and communities; populations at special risk of work-related exposures including women, under-represented minorities, immigrants, and other vulnerable groups such as temporary, contingent and informal sector workers; the effectiveness of interventions addressing exposure and risk including production technologies, work process engineering, and personal protective systems; policies and management approaches to reduce risk and improve health and well-being among workers, their families or communities; methodologies and mechanisms that underlie the quantification and/or control of exposure and risk. There is heavy pressure on space in the journal, and the above interests mean that we do not usually publish papers that simply report local conditions without generalizable results. We are also unlikely to publish reports on human health and well-being without information on the work exposure characteristics giving rise to the effects. We particularly welcome contributions from scientists based in, or addressing conditions in, developing economies that fall within the above scope.
