Abstract |
Metalworking fluid mists pose potential respiratory, cancer, and dermatological concerns for machinists and other exposed workers. Thus, measuring mist concentrations accurately for regulatory and health study purposes is important. However, most metalworking fluids are semi-volatile. This leads to the possibilty that collected mist droplets can evaporate from sampling filters after they have been captured. If this evaporation occurs, mist concentrations wil be underestimated. The purpose of this research was to utiize numerical modeling, laboratory experimentation, and field measurements to determine important factors that might influence the extent of evaporative losses of metalworking fluid mist from sampling filters. Numerical models were developed (1) to predict the evaporation of droplets from the point of generation until sampling onto a fiter, and then (2) to predict the amount of the sampled mist that evaporated from the fiters. |
