NTP Report on Carcinogens Background Document for Strong Inorganic Acid Mists Containing Sulfuric Acid.

摘要

Sulfuric acid mist has been the most extensively studied of the acid mists. Its human effects depend on many factors such as particle size, water solubility, free hydrogen ion concentration, and presence of other chemicals in the aerosol particle. Acid aerosols as a group have been designated one of six criteria pollutants by the U.S. Environmental Protection Agency because of their increasing presence from various human activities and their potential to cause or aggravate health effects, particularly within the respiratory tract. Sulfuric acid mist may contain aerosol particles up to a few micrometers in diameter; generally, the smaller the particle, the deeper it may penetrate into the lung. Local corrosive effects on skin and mucous epithelia from sulfuric acid mist may occur upon exposure to adequate levels.
