Particle size distribution of workplace aerosols in manganese alloy smelters applying a personal sampling strategy.
Air samples were collected by personal sampling with five stage Sioutas cascade impactors and respirable cyclones in parallel among tappers and crane operators in two manganese (Mn) alloy smelters in Norway to investigate PM fractions. The mass concentrations of PM collected by using the impactors and the respirable cyclones were critically evaluated by comparing the results of the parallel mea...
متن کاملIs the size distribution of urban aerosols determined by thermodynamic equilibrium? An application to Southern California
A size-resolved equilibrium model, SELIQUID, is presented and used to simulate the size–composition distribution of semi-volatile inorganic aerosol in an urban environment. The model uses the efflorescence branch of aerosol behavior to predict the equilibrium partitioning of the aerosol components between the gas phase and a size-resolved aerosol population over the entire RH domain. Prediction...
متن کاملToxicity of paraquat and diquat aerosols generated by a size-selective cyclone: effect of particle size distribution.
inspection. Paraquat has an irritant action on the lungs, and at lethal concentrations death is delayed and is associated with pulmonary haemorrhage and oedema. After single exposures the LC50 appears to be a function of the duration and of the concentration; in the rat the lethal concentration-time product (CT) is about 6 ,ug./l. hr. Guinea-pigs and male mice are about as sensitive as rats. Fe...

متن کاملParticle Size Analysis of Aerosols from Medicinal Inhalers
Methods currently in use for the in-vitro measurement of the particle size distribution of aerosols from medical inhalers are reviewed with emphasis on their applicability both for product development and quality control testing and for simulation of likely performance in clinical use. Key attributes and limitations of the various techniques are identified, and consideration is also given both ...
