| 摘 要： | 1INTRODUCTION The ubiquitous distribution and known toxicity of lead pollution in urban environment are posinggreat concern, in term of human health and environment (JULIE and ALEX, 2001). In recent years various human activities, such as automobile exhaust, waste disposal, paint, lead smelting and refining, battery disposal, as well as coal and fuel combustion have implied notable contributions to the increase of environmental lead concentration (SUTHERLAND et al., 2003). Pb is an…

| Abstract: | The horizontal and vertical distribution characteristics of Pb in urban soil of Shenyang City, China were investigated in this study. The range of Pb concentration in the soil was 22.02-2910.60mg/kg. The standard deviation was 443.07mg/kg, and coefficient of variation was 1.64. Tiexi District was seriously contaminated by lead. In general, Pb concentration in the soil decreased with distance from pollution source. Lead concentration varied in different functional areas with the order of industrial area>commercial area>residential area>suburb>reference area. Pb concentration decreased with the depth of soil profile. Both geo-accumulation index and ecological risk index were used to estimate the potential risk of soil Pb pollution in Shenyang City. The results showed that the high potential risk area included Tiexi District and traffic roads. |
