Title Occupational exposure to 4,4'-bipyridyl vapor and aerosol during paraquat manufacturing
Bibliographic information Aug. 1993, Vol.54, No.8, p.440-445. Illus. 11 ref.
Abstract The concentrations of 4,4'-bipyridyl both as vapour and as aerosol were determined in a paraquat factory. The aerosols were the major source of exposure for the workers. The major mass fraction of aerosols had aerodynamic diameters of 3.3-5.8Ám. An enclosure hood had an efficiency of 88% and 82% for aerosols and vapour respectively.
