| Abstract/Contents: | SUMMARY: Sodium chloride is used as the standard di-icing agent on motorways in England at annual application rates varying from 2 to 20 tonnes per lane km. the severity of winter weather strongly influences the application rate, which varied from about 4 to about 13 t lane/km as a mean over the whole country, between 1974 and 1979. Similar variations in application rate occurred between southern and northern regions, averaged over a period of several years. Sodium concentration in the 0-50 mm layer of the soil of central reserves fluctuated considerably. Maximum values, usually in January-March, were often several times the minima found in September or October. Soil sodium concentrations in April were correlated with salt usage rates during the previous winter and showed similar regional and altitudinal variability. In the 0-50 mm layer of soil, sodium levels varied from <500 ug g-1 to several thousand ug g-1. Sodium was more persistent in the soil than chloride. In April the highest concentration of sodium, and often also of chloride, was found in the 0-50 mm layer of the soil profile. By October much of the sodium had been transported to greater depth, and much of the chloride had disappeared from the soil. Observations extending over 6 years suggested that there was no consistent annual increase in the salinity of the soils of central resrves. |
