The new runway deicer on the streets of Moscow is not going to change soil salinity in the first place it is necessary to drastically reduce the amount of technical salt, which has grown by 2.7 times since 2010, RIA Novosti said department head Department of Soil Science, Moscow State University Dmitry Hamsters.
Earlier Tuesday, the head of the Department of Housing and Public Works of Andrew Tsybin said the cleaning of roads this winter city authorities will buy a new agent — based bischofite (magnesium chloride).
"The three known chloride — sodium, magnesium and calcium — melted ice and snow about the same. Therefore, to say that bischofite is a new step forward — wrongly, it is equivalent products. Will there be a better or worse — depending on the volume in which the reactants apply. If we go back to the salt load of the city in 148 tons — it will be the most important health benefits, and if we pour back 420,000 tons of salt in the city, then the negative effects of any salts very quickly affect the soil, people and green areas, "- said the hamsters that is an honorary worker Housing Moscow.
According to him, the salt load in the land of the city has increased by 2.7 times from 2010 until the time the use of salt in the average was 235,000 tons of liquid reactants and only 82,000 tons of solid reactants, and in 2006 stopped using salt sidewalks.
"We were in the city until 2010 salt load of 148 tons. But now, for the second year, we live in a salt stress: the so-called new technology involves the use of the roadway to 200 thousand tons of solid salts and 250 thousand tons of liquid salt, plus salt and marble chips back on the sidewalks of up to 150 thousand tons, "- said Professor MSU.
If this does not change, the city authorities will be faced with repeated salinization and soil degradation, which took place in the capital from 1992 to 2000, when a year on the carriageway spilled 350,000 tons of technical salt.
"Scientists and environmentalists are closely watching the situation closely. Negative effects from the use of high amounts of salt is quite obvious. Them we feel, and our data suggest identify the impact on the soil and green areas", — concluded the scientist.
