Distribution of Perfluorinated Compounds in Surface Water and Soil in Partial Areas of Shandong Province, China

The work investigated the distribution of twelve perfluorinated compounds (PFCs) in surface water and soil in the partial areas of Shandong Province, China. The total concentration of PFCs was in the range of 36.1–1,236.21 ng/L in surface water and 4.23–48.72 ng/g dw (dry weight) in the soil. The concentration of PFOA is higher than that of PFOS in all the surface water and soil. There was a positive correlation between PFOS and PFOA. The ratio method and principal component analysis (PCA) were used to identify the potential source of PFCs in surface water. The results showed that atmospheric precipitation, industrial emissions and domestic sewage were the main reasons for PFCs pollution in the surface water of partial areas of Shandong Province, China.
