Aerosols and Aerosol Propellants in Asthma
JAMA: The Journal of the American Medical Association, 1971To the Editor.— In my practice of diseases of the chest, I have at least 1,000 patients who use and rely on a pressured aerosol device containing isoproterenol. Depending on the extent of their respiratory embarrassment, they use this device from 1 to 20 times a day.

Clinical aerosols II. Therapeutic aerosols
Archives of Internal Medicine, 1982The current uses of clinical aerosols such as water, saline, mucolytics, bronchodilators, cromolyn sodium, corticosteroids, and antimicrobials have been reviewed. The benefits of water, saline, and detergent aerosols continue to be surrounded by uncertainty and controversy.

Atmospheric aerosols: composition, transformation, climate and health effects.
Angewandte Chemie, 2005Aerosols are of central importance for atmospheric chemistry and physics, the biosphere, climate, and public health. The airborne solid and liquid particles in the nanometer to micrometer size range influence the energy balance of the Earth, the ...

Science, 1974
To determine the effects of atmospheric aerosols on the radiative heating of the earth-atmosphere system, the radiative transfer equation is solved analytically in the two-stream approximation. It is found that the sign of the heating is independent of optical thickness of an aerosol layer and the amount of heating approaches a finite limit with ...

Respiratory Care Clinics of North America, 2001
The success of aerosol therapy depends upon the delivery of ample amounts of the drug to appropriate sites in the lung with minimal side effects. Successful aerosol therapy delivery systems must provide sufficient respirable particles or droplets, with minimal loss of the drug. Ultimately, the patient must be able to use the device easily, maintain it,

Aerosol sampler for analysis of fine and ultrafine aerosols
Analytica Chimica Acta, 2018A new aerosol sampler based on the original version of Aerosol Counterflow Two-Jets Unit (ACTJU) is described. The ACTJU collector, connected with a water-based Condensation Growth Unit (CGU) placed upstream of the ACTJU, accomplished the quantitative collection of fine and ultrafine aerosol particles down to a few nanometers in diameter.
