EVALUATION OF CYTOTOXICITY AND GENOTOXICITY OF CHEMICAL MATERIAL IN PM2.5 FILTERS FROM THREE MONITORING STATIONS OF THE AIR QUALITY NETWORK OF THE ABURRÁ VALLEY

The increase in air pollution and its adverse effects has raised concerns about regulatory policies and has encouraged the development of new air quality standards.Environmental toxicants can have various effects ranging from irritation to cell and tissue death; however, some genotoxic compounds produce alterations in the genetic material or its associated components, causing mutations or interfering with some repair or polymerization processes involved in chromosome segregation.The objective of this study was to evaluate the effect on the viability and genotoxic potential of PM 2.5 particulate matter obtained from filters collected from three monitoring stations of the air quality network in the Aburr Valley, Colombia, on the CHO-K1 and Jurkat cell lines.The tests carried out revealed a reduction in cell viability and punctual damage to DNA.The results suggest that PM 2.5 material has genotoxic potential and can induce cancer development, as has been suggested in other studies.
