Isocyanates can present respiratory hazards as particulates, vapors or aerosols. Sulfates occur as microscopic particles (aerosols) resulting from fossil fuel and biomass combustion. Nuclear meteorology investigates the distribution of radioactive aerosols and gases in the atmosphere. Inhalants are gases, aerosols, or solvents that are breathed in and absorbed through the lungs. Proposed methods include increasing the planetary albedo, for example using stratospheric sulfate aerosols. Furthermore, it is highly reactive and interacts with other greenhouse gases and aerosols. The compressed air aerosols the fluid, dispersing fine droplets. It does not include other forcings, such as aerosols and changes in solar activity. Lidars can determine atmospheric profiles of aerosols, clouds, and other constituents of the atmosphere. The composition of aerosols and particles depends on their source. Dermal dosage forms include&colon; liniments, braces, lotions, ointments, creams, dusting powders, aerosols, and transdermal patches. The propylene glycol-containing liquids produced the most amounts of carbonyls in e-cigarette aerosols. Human-made sulfate aerosols, primarily from burning oil and coal, affect the behavior of clouds. Direct attribution of the stratospheric aerosols to pyroCbs only occurred in the last decade. For atmospheric aerosols the values available are scattered and limited.
