This was a project conducted by a Master's of Science degree student, Nazila Shakibaei, in the Department of Environmental and Occupational Health Sciences, in collaboration with the Field Research and Consultation Group. The goals of this study were to evaluate four local exhaust ventilation (LEV) systems to determine their effectiveness at eliminating vapors and dust from the breathing zone of nail salon technicians and their clients and to assess the overall efficiency of the systems in an isolated static exposure chamber. The work was presented and recorded as a webinar for the National Healthy Nail and Beauty Salon Alliance on February 3, 2105. The webinar can be viewed below. The project was funded by the Local Hazardous Waste Management Program in King County, WA. For more information on this project, please email email@example.com.
