Distribution characteristics of soil and groundwater pollutants in a chemical park site
This study takes a typical chemical industry park in the Yangtze River Economic Belt as an example to explore the distribution,risks,and management strategies of soil and groundwater pollution in the park.Through on-site investigation and sampling analysis,the pollution status of soil and groundwater inside and outside the park was systematically monitored,and the spatial distribution and composition characteristics of pollutant concentration levels were evaluated using differential analysis,correlation analysis,etc;The correlation between multi-level deep soil and groundwater pollutants was studied.The results showed that the soil pollutants in the park did not exceed the standard,but the concentrations of Ni(p=0.018)and Cu(p=0.023)were significantly higher than those around the park,and the Hg(p=0.074)around the park was higher than inside;Various indicators such as 1,2-dichloroethane,Mn,Pb,and dichloromethane in groundwater pollutants exceed national standards,and some points have a high degree of exceeding the standard,indicating that groundwater has been severely polluted.At the same time,the overall correlation between groundwater pollutants in the park and multi-level deep soil pollutants is low.This study provides a scientific basis for the environmental risk assessment and restoration plan design of the park,and provides scientific support for the ecological environment protection and sustainable development of the Yangtze River Economic Belt.
