Genotoxic and oxidative effects induced on A549 cells by extract of PM10 collected in an electric steel plant.

The present study was aimed at assessing the carcinogenic risk of occupational exposure to PM10 in electric steel plants. PM10 was collected on cellulose filter respectively outside (site 1) and inside (site 2) the furnace area, was measured, extracted and its metal content was analysed by ICP-MS. Cells were exposed for 30 min, 2 and 4 hours to extract of filter from each site diluted at 0.
