Aerosol particles are referred to as dust, fume, mist, or particulates, depending on their generation process. In meteorology, they may also be called fog, mist, haze, or smog based on visibility and color differences. The properties of aerosol particles are represented by many factors, including particle size, chemical composition, shape, and optical and electrical characteristics, making them extremely complex.<\/p>\n\n\n\n<p>For example, regarding particle size, the range can vary widely from approximately 0.001 \u03bcm (1 nm), which is nearly equal to that of molecules or ions, to about 100 \u03bcm, similar to pollen, covering about five orders of magnitude. Additionally, the number concentration can range from about 10 particles\/cm\u00b3 in clean air to around 10<sup>6<\/sup> to 10<sup>10<\/sup> particles\/cm\u00b3 near sources of emission, spanning 7 to 8 orders of magnitude. Furthermore, in recent ultra-clean rooms, requirements have risen to about 10<sup>-5<\/sup> particles\/cm\u00b3.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/sites.google.com\/view\/aerosolpedia\/home\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"201\" src=\"https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-1024x201.png\" alt=\"\" class=\"wp-image-979\" srcset=\"https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-1024x201.png 1024w, https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-300x59.png 300w, https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-768x151.png 768w, https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-1536x302.png 1536w, https:\/\/jaast.jp\/wp-content\/uploads\/2025\/09\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-01-6.37.28-2048x403.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/sites.google.com\/view\/aerosolpedia\/home\">https:\/\/sites.google.com\/view\/aerosolpedia\/home<\/a><\/figcaption><\/figure>\n\n\n\n<p>\u65e5\u672c\u30a8\u30a2\u30ed\u30be\u30eb\u5b66\u4f1a\u304c\u904b\u55b6\u3059\u308b\u30a8\u30a2\u30ed\u30be\u30eb\u7528\u8a9e\u89e3\u8aac\u30b5\u30a4\u30c8\u3000<strong>\u30a8\u30a2\u30ed\u30be\u30eb\u30da\u30c7\u30a3\u30a2\uff08Aerosolpedia\uff09<\/strong>\u304c\u5225\u306e\u30b5\u30a4\u30c8\u306b\u3042\u308a\u307e\u3059\u3002\u7686\u69d8\u306b\u3054\u6d3b\u7528\u3044\u305f\u3060\u3051\u308c\u3070\u5e78\u3044\u3067\u3059\u3002JAAST has initiated the aerosol terminology explanation site, Aerosolpedia.
