Abstract
Road maintenance chlorides have a negative environmental impact. Chemical solutions of melting snow inevitably get into the soil and change its chemical composition. They also get into ponds. Five water basins in Vilnius city, at 5–80 m from roads, were chosen for investigation. The highest chloride concentrations were established by roads where winter road maintenance is performance at the highest level. The hydrophysical and chemical parameters of the investigated lakes depend on anthropogenic processes. Diatoms were used as indicators for reconstruction of the paleo‐ecological history of the lakes. They respond sensitively to changes in lake water salinity. The total number of 35 indifferentic‐halophilic species from all the 78 diatom taxa were identified in the lake bottom sediments. Fluctuations of their abundance could be caused by the impact of salts in different periods stimulating the productivity of indifferentic‐halophilic specie
Highlights
The roads of the Republic of Lithuania are maintained in winter conditions almost 5 months per year [1]
The highest chloride concentrations of roadside snow were found at a distance of 01 m from a road. It reaches 3120 mg/l, pH of dissolved snow water is between 7,27,4
The highest chloride concentrations are established by roads where winter road maintenance is performed at the highest level
Summary
The roads of the Republic of Lithuania are maintained in winter conditions almost 5 months per year [1]. It is caused by geographical position and climate. During winter road maintenance to avoid road slippery fractional materials (mostly sand), chemical substances (mostly salts) and their blends are used. Salts react with ice and solutions which do not freeze are the result of this chemical process. Chlorides used for road maintenance have a negative environmental impact. Chemical solutions of melting snow inevitably get into the soil and change its chemical composition.
