The study was taken to evaluate the pollution status of the industrial park and establish a database for pollutant source. A total of 398 soil samples from seven different industry types were collected in a typical industrial park in Ningxia.The contents of heavy metals and polycyclic aromatic hydrocarbons in the samples were detected

and the pollutant chemical fingerprint database was established. The results showed that except for dibenzo [a

h] anthracene in industrial land for comprehensive utilization of abandoned resources

the contents of heavy metals and polycyclic aromatic hydrocarbons in the samples did not exceed the second type of land use screening value. However

some pollutants contents exceeded the soil background value in Ningxia and the first level standard value

indicating the pollution phenomenon existed. By defining four pollution fingerprint levels

an industry-based fingerprint database of chemical pollutant was successfully established

which can provide a reference for pollution control and pollutant source identification.
