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):

Some people used the platform to organize ahead of the storming of the U.S. Capitol in January 2021, and last month Senator Mark Warner sent a letter to Durov urging him to curb Russian information operations on Telegram. On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change. At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. There was another possible development: Reuters also reported that Ukraine said that Belarus could soon join the invasion of Ukraine. However, the AFP, citing a Pentagon official, said the U.S. hasn’t yet seen evidence that Belarusian troops are in Ukraine.
