- Pollutants 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.
