Performance Characteristics of Personal Samplers in Still and Moving Air
Personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. This work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. Velocity profiles have been measured around and within typical cylindrical sampling devices, ...
متن کاملCollection efficiency and capacity of three samplers for acidic and basic gases.
This paper compares the collection efficiency and capacity of a coated porous metal disk with those of a silica gel tube and an impinger at the acid or basic aerosol concentration of two times the permissible exposure limitation (Taiwan IOSH, Institute of Occupational Safety and Health), relative humidity of 80 +/- 5%, and temperature of 30 +/- 3 degrees C in the laboratory. Using 5% sodium car...
متن کاملNew samplers for collection of sea mud.
To obtain specimens from marine environment, water sampling devices such as Nansen's sampler and sediment sampling device such as a gravity-core sampler are used for geological or ecological examinations in oceanic or aquatic fields. Those samplers are able tocollect a reasonable amount of specimens for the above studies. These devices are all considerably heavy and operated by means of a rope ...
متن کاملEvaluation of Car Air Filters’ Efficiency as Active Samplers for Polycyclic Aromatic Hydrocarbons and Heavy Metals
In this study, an innovative and inexpensive approach, based on car engine air filters (CAFs), was used to monitor polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs). CAFs were collected from two taxi garages in Guangzhou and analyzed for PAHs and heavy metals. The total concentrations of eight high molecular weight PAHs (ΣPAHs) ranged from 923 to 11378 μg/CAF. The average ΣPAHs con...
