В воздухе постоянно присутствуют мелкие (менее 50 микрон) частицы – аэрозоли. Аэрозоли могут быть: - естественного происхождения: частицы почвы, дыма лесных и травяных пожаров, морской соли и частиц тумана. - искусственного сажа от выхлопа двигателей внутреннего сгорания, печного и газового отопления, предприятий, пыль карьеров.
Мы используем в наших наблюдениях прибор измеряющий массу аэрозольных частиц РМ10 и PM2,5 приведенную к 1 литру воздуха (мкг/л).
А так же концентрацию частиц в 1 литре воздуха размеров (шт./л):

'Wild West' The perpetrators use various names to carry out the investment scams. They may also impersonate or clone licensed capital market intermediaries by using the names, logos, credentials, websites and other details of the legitimate entities to promote the illegal schemes. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. The company maintains that it cannot act against individual or group chats, which are “private amongst their participants,” but it will respond to requests in relation to sticker sets, channels and bots which are publicly available. During the invasion of Ukraine, Pavel Durov has wrestled with this issue a lot more prominently than he has before. Channels like Donbass Insider and Bellum Acta, as reported by Foreign Policy, started pumping out pro-Russian propaganda as the invasion began. So much so that the Ukrainian National Security and Defense Council issued a statement labeling which accounts are Russian-backed. Ukrainian officials, in potential violation of the Geneva Convention, have shared imagery of dead and captured Russian soldiers on the platform. On Feb. 27, however, he admitted from his Russian-language account that "Telegram channels are increasingly becoming a source of unverified information related to Ukrainian events."
