摘要

The Xiao River sewage irrigation area in Luancheng where wastewater from Shijiazhuang flows through was taken as the research area. Five groundwater monitoring wells were set perpendicular to Xiao River, the research reveals the migration law and distribution characteristics of poisonous metal lead, through collecting and analyzing soil samples at different depths, investigating lithologic structure and pollution. The result shows that soil type has great impact on vertical lead distribution in aeration zone, which means that lead concentrates more in clay than in sand. Lead migrates fast in silty soil and silty clay, but slow in sand. The content of lead soil adsorbed decreases with grain size increasing. The most important factor influencing the distribution of lead is the soil type.
