DEICING REAGENTS IN URBAN ECOSYSTEMS, USING THE EXAMPLE OF MOSCOW

Deicing reagents have an impact on the environment. The composition of the deicing reagents used in Moscow has undergone certain changes. However, the main components of deicing reagents were chlorides, including calcium chloride and (or) sodium chloride. We also conducted research on the effects of sodium chloride and calcium chloride on some urba...
