Perfluorinated compounds (PFCs) and organochlorine pesticides (OCPs) were analyzed in surface soils along the Huaihe River. Sixteen target PFCs and nine OCPs were quantified in soils from a region of intensive industrial and agricultural development. Concentrations of PFCs and OCPs ranged from less than the limit of detection (LOD) to 1.22 ng/g and 3.63 to 227 ng/g, respectively. Contamination by OCPs was more serious than that of PFCs, which was consistent with the fact that OCPs were widely used in agriculture of the district while there was no known production or application of PFCs in the study area. The predominant PFCs in soils were PFOA and PFOS with concentrations that ranged from <LOD to 0.20 ng/g and <LOD to 0.21 ng/g, respectively. Among the three groups of OCPs, average concentrations of HCHs, DDTs, and HCB were 4.7, 23.7, and 1.4 ng/g, respectively. Results of principal component analysis revealed relatively weak associations between concentrations of PFCs and those of OCPs, while concentrations of OCPs exhibited similar patterns of distributions. Among the mainstream and five tributaries, the highest concentrations of PFCs were observed along the Pihe River, while the highest concentrations of OCPs occurred along the Xifeihe River. In general, concentrations of PFCs were evenly distributed, while those of OCPs exhibited relatively greater spatial differences.
沿淮河流域表层土壤中多氟化合物（PFCs）和有机氯农药（OCPs）的分析。在一个工业和农业发达地区的土壤中定量分析了 16 种目标 PFCs 和 9 种 OCPs。PFCs 和 OCPs 的浓度范围分别为检测限以下至 1.22ng/g 和 3.63 至 227ng/g。OCPs 的污染比 PFCs 更严重，这与 OCPs 在该地区农业中广泛使用而研究区域内没有已知的 PFCs 生产或应用的事实一致。土壤中主要的 PFCs 是 PFOA 和 PFOS，浓度范围分别为<LOD 至 0.20ng/g 和<LOD 至 0.21ng/g。在这三组 OCPs 中，HCHs、DDTs 和 HCB 的平均浓度分别为 4.7ng/g、23.7ng/g 和 1.4ng/g。主成分分析的结果表明，PFCs 浓度与 OCPs 浓度之间的相关性较弱，而 OCPs 浓度表现出相似的分布模式。在主流和五条支流中，皮河的 PFCs 浓度最高，而西废河的 OCPs 浓度最高。总的来说，PFCs 的浓度分布均匀，而 OCPs 的浓度则表现出较大的空间差异。
