Spreading a large amount of industrial salt on highway de-icing will have what impact?

Industrial salt snow removal has many hazards. First of all, it has caused great damage to the environment and greening. Due to the extensive use of sodium chloride during snow removal in winter, a large amount of snow water containing chloride ions seeps into the roots of plants, forming reverse osmosis, absorbing a large amount of water in the plants, causing the plants to lose water; at the same time , a large amount of snow containing salt and snow melting agents melts and flows into ditches and farmland, salinizing the soil on both sides of the line, seeping into the ground and contaminating groundwater; secondly, it also causes damage to structures, and large amounts of chlorine in salt and snow melting agents After acidic ions such as ions penetrate into the concrete with salt water, they react chemically with the iron in the steel bars, accelerating the corrosion and expansion of the iron, causing the protective layer to peel off, and ultimately causing structural damage to bridges and roads.
