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

These administrators had built substantial positions in these scrips prior to the circulation of recommendations and offloaded their positions subsequent to rise in price of these scrips, making significant profits at the expense of unsuspecting investors, Sebi noted. 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. Telegram has become more interventionist over time, and has steadily increased its efforts to shut down these accounts. But this has also meant that the company has also engaged with lawmakers more generally, although it maintains that it doesn’t do so willingly. For instance, in September 2021, Telegram reportedly blocked a chat bot in support of (Putin critic) Alexei Navalny during Russia’s most recent parliamentary elections. Pavel Durov was quoted at the time saying that the company was obliged to follow a “legitimate” law of the land. He added that as Apple and Google both follow the law, to violate it would give both platforms a reason to boot the messenger from its stores. Despite Telegram's origins, its approach to users' security has privacy advocates worried. NEWS
