When food or drink is brought into an environment where harmful chemicals are unsealed there is the possibility of those chemical vapors or particles contaminating the food or the drink.
The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Aerosol photometers utilize light scattering as a detection method, and generally are lighter, more rugged, and have continuous readout relative to other direct-reading aerosol monitors. Photometers generally cannot discriminate between different types of aerosol, and background dust and water droplets can overwhelm readings for the target aerosol.

The aerosol spray canister invented by USDA researchers, Lyle Goodhue and William Sullivan. The concepts of aerosol probably go as far back as 1790.
