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

Stocks dropped on Friday afternoon, as gains made earlier in the day on hopes for diplomatic progress between Russia and Ukraine turned to losses. Technology stocks were hit particularly hard by higher bond yields. And indeed, volatility has been a hallmark of the market environment so far in 2022, with the S&P 500 still down more than 10% for the year-to-date after first sliding into a correction last month. The CBOE Volatility Index, or VIX, has held at a lofty level of more than 30. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so. Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations.
