Assessment of Soil Environmental Quality in Huangguoshu Waterfalls Scenic Area
This paper concentrates on five major heavy metal pollutants as soil environmental quality evaluation factors,respectively Lead(Pb),Cadmium(Cd),Mercury(Hg),Arsenic(As),Chromium(Cr),based on the National Soil Environmental Quality Standards(GB15618-1995),we used single factor index evaluation model of soil environmental quality and comprehensive index evaluation model to analyze surface soil environmental quality in the Huangguoshu Waterfalls scenic area.Based on surface soil analysis,our results showed that the individual contamination index,Pb,Hg,As and Cr in the Huangguoshu Waterfalls scenic area met class Ⅰaccording to requirements of National Soil Environmental Quality Standards,which indicated that Pb,Hg,As and Cr were not main heavy metal pollutants in this area,but the individual contamination index of Cd in soil was seriously exceeded National Soil Environmental Quality Standards requirement.Soil environmental quality in Shitouzhai,Luoshitan,Langgong Hongyan Power Plant have exceeded the requirement of National Soil Environmental Quality Standards 0.7< Pc≤ 1.0(Alert Level),these soils had been slightly polluted; the classification of soil environmental quality assessment in Longgong downstream area was above Alert Level,it indicated that soil in this area was not polluted.Above all,relevant measures for soil remediation are put forward.
