Dust at Various Workplaces-Microbiological and Toxicological Threats.

ABSTRACT: The aim of the present study was to evaluate the relation between the chemical (analysis of elements and pH) and microbiological composition (culture and metagenomics analysis) of the dust at various workplaces (cement plant, composting plant, poultry farm, and cultivated area) and the cytotoxicity effect on the human adenocarcinoma lung epithelial adherent cell line A-549 (MTT assay test). Analysis of the Particulate Matter (PM) fraction showed that the dust concentration in cultivated areas exceeded the OELs. For the remaining workplaces examined, the dust concentration was lower than OELs limits. The number of microorganisms in the dust samples was 3.8 × 10²⁻1.6 × 10⁸ CFU/g bacteria and 1.5 × 10²⁻6.5 × 10⁶ CFU/g fungi. The highest number of microorganisms was noted for dust from cultiva
