Abstract This study evaluates airborne microorganisms and aerosols from soluble metalworking fluids (MWFs) in the working environment. Air quality parameters (endotoxin levels, culturable airborne microorganisms, fluid mist, inhalable dust and air exchange rates) were evaluated at 44 sites in 25 shops in Quebec, Canada. Microorganism concentrations were also measured in MWF. Most workplaces respected the recommended maximum values for fluid mist and showed low concentrations of airborne endotoxin, culturable microorganisms and inhalable dust despite fluid contamination, even when air exchange rates were below the recommendations. Airborne Pseudomonas pseudoalcaligenes was recovered from many sites at significant concentrations. Possible health-associated risks from exposure to this microorganism need to be further investigated.
