Accumulation of Deicing Salts and its Short-Term Effect on Metal Mobility in Urban Roadside Soils
Widespread use of deicing salts on road in cold regions has been shown to mobilize heavy metals in roadside soils putting ground and surface waters at risk.Urban areas are responsible for a large portion of deicing salts use in northeastern China.Examining the accumulation of deicing salts and its short-term effect on metal mobility in urban roadside soils is important for understanding the distribution and movement of heavy metals in the environment.Sodium chloride (NaCl) is the most commonly applied roadway deicer due to its efficacy and economy.The early spring concentration of principal anions (Na+ and Cl-) and heavy metals (Cd and Pb) were monitored in the soils from 41 roadside objects in the central urban area of Shenyang city,the largest heavy industrial base city in Northeastern China.Furthermore,soil column leaching experiments were conducted to evaluate the mobility of heavy metals from the contaminated soils in response to the increased ion concentration resulted from deicing salts input.
