“…As seen from a study on 79 surface soil samples from 17 coastal sites in North China, an average concentration of 0.98 ng·g −1 ·dw was reported [22], which was comparable to our value for Liaoning Province, higher than Sichuan Province, and lower than Shandong Province. The concentration of ∑PFAAs in soils around the Koshi River in Nepal ranged from ND (below the detection limit) to 1.78 ng·g −1 ·dw, showing a slightly lower concentration compared to those in China [26].…”

“…Fluorine chemical industries located in Shandong and Liaoning play important roles in terms of point emission sources and PFAA contamination, dominated by PFOA and PFOS [22]. Two agricultural producing areas in the provinces of Liaoning and Shandong were studied, with Sichuan Province considered for comparison.…”

Field investigations on perfluoroalkyl acid (PFAA) levels in various environmental matrixes were reported, but there is still a lack of PFAA level data for agricultural environments, especially agricultural producing areas, so we collected soil, irrigation water and agricultural product samples from agricultural producing areas in the provinces of Liaoning, Shandong and Sichuan in China. The background pollution from instruments was removed and C4–C18 PFAAs were detected by LC-MS/MS. The concentrations of PFAAs in the top and deep layers of soil were compared, and the levels of PFAAs in different agricultural environments (greenhouses and open agriculture) were analyzed. We found the order of PFAA levels by province was Shandong > Liaoning > Sichuan. A descending trend of PFAA levels from top to deep soil and open to greenhouse agriculture was shown and perfluorobutanoic acid (PFBA) was considered as a marker for source analysis. Bean vegetables contribute highly to the overall PFAA load in vegetables. A significant correlation was shown between irrigation water and agricultural products. The EDI (estimated daily intake) from vegetables should be of concern in China.

Quantitative study of urban-rural gradients for persistent organic pollutants (POPs) concentrations is extremely important for understanding POPs behavior and for ecological risk assessment and management. However, little has been studied about quantitative calculation for soil concentrations of POPs from urban to rural areas. In this paper, 153 soil samples were collected in the coastal region of Bohai Sea and Yellow Sea, and the distributions of polychlorinated biphenyls, Polyaromatic hydrocarbons, Perfluoroalkyl and polyfluoroalkyl substances were examined. Urbanrural gradient model (URGM) was derived by using atmospheric point source diffusion model combined with fugacity model to prove potential mathematical relationships among urban and rural soils, and the URGM was proved suitable for simulating urbanrural soil concentrations through validation of measured data. Significantly linear correlation was found between POPs amount in surface soil and city population, between POP concentrations and the artificial surface area. Urban-rural POPs concentrations were simulated by URGM model, and calibrated by urban population and land-cover data. The results showed that it was suitable for simulating urban-rural POPs concentrations at a regional scale. This study could provide a new method for quantifying urban-rural gradients for POPs concentrations, and promote quantitative research on coupling between land cover, socioeconomic data and POPs concentrations.
