aerosol
Significado: A suspension of fine solid particles or liquid droplets in a gas; also the pressurised container used to disperse such a suspension as a spray.
Aerosol has both a scientific and an everyday meaning. In atmospheric science and public health, aerosols include dust, pollen, sea salt, and pollutant particles suspended in the air — these play important roles in climate, air quality, and disease transmission (as demonstrated during the Covid-19 pandemic). In everyday British English, 'aerosol' typically refers to the spray can itself — deodorant, paint, or cleaning products. The environmental impact of aerosol propellants (CFCs) was a major issue in the 1980s, leading to the Montreal Protocol. Common collocations include 'aerosol transmission,' 'aerosol spray,' and 'aerosol particles.'

Origen e historia
Coined in the early 20th century from 'aero-' (Greek aēr, air) and 'sol' (short for solution). The term was first used in scientific literature around 1920 and entered popular usage with the development of pressurised spray cans in the 1940s.
