aerosol
エアロゾル
解説 Definition
aerosol は、空気中に細かい液体や固体の粒子が広がっているものを指す名詞です。スプレー缶から出る霧状の物質や、大気中の微粒子を説明するときに使われます。
An aerosol is a suspension of very small solid particles or liquid droplets in a gas, especially in the air. In everyday usage, the word may also refer to a substance dispensed as a fine spray or to its pressurized container.
覚え方のコツ Memory Tip
aerosol は aero-「空気」と sol「ゾル」を組み合わせた科学語で、「空気などの気体中に微粒子が散った系」と形から理解できます。aerosol spray、aerosol can、atmospheric aerosols の組み合わせで覚えましょう。日常語では容器や噴霧製品を指すこともありますが、科学では浮遊粒子の集まりが中心です。
Divide aerosol into aero-, suggesting air, and sol, a chemistry term for a colloidal dispersion. This gives the central scientific picture: tiny solid particles or liquid droplets spread through a gas. Atmospheric aerosols include particles suspended in air, while a household aerosol may be a cleaner or paint released as a fine spray. Learn the common combinations aerosol spray, aerosol can, and atmospheric aerosols. Remember that spray describes the act or pattern of dispersal, whereas aerosol can name the suspended particles, the dispensed substance, or, in everyday usage, the container.
例文
The cleaner comes out of the can as an aerosol.
その洗剤は缶からエアロゾルとして出てきます。
Scientists study aerosols in the atmosphere.
科学者たちは大気中のエアロゾルを研究しています。
Do not spray the aerosol near a flame.
火の近くでそのエアロゾルを噴射しないでください。

aerosol の語源・成り立ち Etymology
aerosol は aero-「空気」+ sol「ゾル、コロイド溶液」からなる近代科学語です。aero はギリシャ語 aer「空気」、sol は solution に通じるため、「空気中に細かく散った粒子」という意味が形から読めます。
Aerosol is a modern scientific formation combining aero-, from Greek aēr, meaning “air,” with sol, a term for a colloidal suspension. Sol was formed in scientific vocabulary in association with solution, although a sol is specifically a type of colloidal dispersion rather than an ordinary solution. Aerosol was modeled to describe a system in which minute particles are dispersed in a gas instead of a liquid. Its meaning later expanded in everyday English to include pressurized spray products and their containers.
