Se hela listan på earthobservatory.nasa.gov Aerosol, a system of liquid or solid particles uniformly distributed in a finely divided state through a gas, usually air. Aerosol particles, such as dust, play an important role in the precipitation process, providing the nuclei upon which condensation and freezing take place. Se hela listan på scienceclarified.com Physical and chemical substances used as medical aerosols include drugs that act as bronchodilators and decongestants, such as epinephrine, ephedrine, isoproterenol, atropine, and the steroids. Wetting agents administered as aerosols to render the bronchial secretions more liquid include tyloxapol and acetylcysteine.
The particulate matter may be in the form of dusts, fumes, or mist. Aerosols in the atmosphere are

Particles less than 0.1 μm, known as Aitken particles, have a short residence time in the troposphere since they are removed quickly by diffusion. Aerosols are also found in a part of the atmosphere just above the troposphere (stratosphere). A severe volcanic eruption, such as Mount Pinatubo in the Philippines in 1991, can put large amounts of aerosol into the stratosphere that remain there for many months, producing beautiful sunsets around the globe, and causing summer temperatures to be cooler than normal. Aerosols are suspensions of fine solid particles or liquid droplets in a gas. Clouds, for example, are aerosols because they consist of water droplets dispersed in the air. Such droplets are produced in a two-step process: first, a condensation nucleus forms, and then volatile molecules condense onto this nucleus, producing a droplet.
All available information shall be considered. An aerosol can be defined as few system could solid the liquid particles suspended in ordinary or other gaseous environment. The mission of OSHA is not ensure accurate safe and healthy workplace for American workers. Probably the most primary form of a fume is smoke. Aerosols are extremely small solid particles, or very small liquid droplets, suspended in the atmosphere. Aerosols consisting of solid particles can be placed in the atmosphere primarily by large dust storms, volcanic eruptions, or the soot particles from large fires.

Some devices for generating aerosols are: Aerosol mass spectrometer (AMS) Differential mobility analyzer (DMA) Electrical aerosol spectrometer (EAS) Aerodynamic particle sizer (APS) Aerodynamic aerosol classifier (AAC) Wide range particle spectrometer (WPS) Micro-Orifice Uniform Deposit Impactor Sea salt, dust, and volcanic ash are three common types of aerosols. (Photograph by Katherine Mann.) The bulk of aerosols—about 90 percent by mass—have natural origins.
