Dirty rains in Moscow account for no more than 3% of precipitation and mostly fall after a long drought. This was told socialbites.ca by a candidate of chemical sciences, a former employee of the Department of Meteorology and Climatology of the Faculty of Geography of Moscow State University. Lomonosov Irina Eremina.
“Overall, rain is the purest water in the world. Especially if they get frequent and heavy rainfall. When they say, “It will rain for a month,” it becomes the purest of rains. If it has not rained for a long time, and then it has fallen, and it is not yet strong, this will be the dirtiest rain, ”explained Eremin socialbites.ca.
The pharmacist cited the year 2010, when there was smoke and no rain in July, as an example. Eremina noted that the rains that fell after that were very dirty. Such precipitates differ from ordinary ones both in the concentration of substances and in their composition.
“Any natural water, including rain, has approximately the same composition. Components are the most common. Cations – calcium, sodium, potassium, magnesium, ammonium. Anions – sulfates, chlorides, nitrates, bicarbonates. Anions include both fluorides and phosphates, but in very small amounts. And they are not in every rain, only in the dirty ones, ”the chemist concluded.
Formerly chemist Eremina announcedIs it possible to drink rainwater?
