Термин TDS расшифровывается как “total dissolved solids” и означает общее количество растворенных в воде частиц, другими словами — общую минерализацию в ppm (parts per million = миллионная доля), что эквивалентно 1 мг/л (миллиграмм на литр), или общему количеству растворенных в воде частиц солей на один миллион частиц воды.
Мы измеряем TDS для оценки переноса и осаждения солей с атмосферными осадками.
Как показали измерения TDS: - талая вода имеет 4 - 5 ppm - дождевая вода 20 ррm - талая вода с проезжей части 1867 ppm

Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report. 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. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. 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. The next bit isn’t clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Fools’ prank. TechCrunch implies that it was a matter of principle, but it’s hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych.
