- Abstract in UndeterminedPollutants in the air can be in gaseous and particle (solid and liquid) phases. Interactions between these phases occur. The components are emitted to the air by different source mechanisms such as evaporation, disintegration of bulk material and chemical reactions. The significance of different transport mechanisms is, for airborne particles, dependent on the aerodynamic properties. Water solubility (for gases) and the aerodynamic properties (for particles) determine the site of deposition in the human airways. In work environments species with different physical, chemical and biological features can be abundant. A variety of methods are used to identify and quantify the pollutants. Remedial actions against health hazards include the substitution of materials and processes; preventing the airborne constituents reaching the environment (enclosures, hoods); local ventilation; general ventilation and respiratory protection.

Personal Aerosol Sampler with Size Fractionation and Time Resolution

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter describes a personal aerosol sampler with size fractionation and time resolution that gives samples for elemental analysis. An impaction stage collects coarse particles and a filtration stage collects finer ones. Sampling in consecutive time intervals is performed on different impaction and filtration surfaces. These sampling surfaces corresponding, for example, to 15-min intervals, may be analyzed with particle-induced X-ray emission analysis (PIXE) for fast, low-cost determination of most of the elements of hygienic interest that are present in aerosols in concentrations far below their current threshold limit values (TLV). The sampler is intended to be used for aerosol measurements in work environments to obtain detailed information on exposures.
