The term refers both to the physical suspension (scientific) and the common consumer product (everyday). In environmental contexts, it often refers to atmospheric pollutants.
Dialectal Variation
British vs American Usage
Differences
Usage is nearly identical. 'Aerosol can' is slightly more common in US English; 'aerosol spray' is equally common in both.
Connotations
In scientific/ecological contexts, both varieties carry negative connotations regarding atmospheric pollution. In consumer contexts, it is neutral.
Frequency
Slightly higher frequency in American English due to broader use in marketing and environmental discourse.

All aerosols are sprays, but not all sprays are aerosols in the technical sense. Technically, an aerosol requires the particles to remain suspended in air for a period. Colloquially, they are often used interchangeably.
Some aerosols (e.g., CFCs) damage the ozone layer. Others, like sulfate particles, can reflect sunlight and cool the planet but also contribute to air pollution and acid rain.
Not in standard English. The correct verbs are 'aerosolise' (UK) / 'aerosolize' (US). 'Spray' is the common everyday verb.
