Perfluorinated Compounds in Greenhouse and Open Agricultural Producing Areas of Three Provinces of China: Levels, Sources and Risk Assessment.

ABSTRACT: 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.

Project description:Nitrate pollution frequently impacts groundwater quality, particularly in agricultural regions across the world, but identifying the sources of nitrate (NO3 -) pollution remains challenging. The extensive use of nitrogen-containing fertilizers, surpassing crop requirements, and livestock management practices associated with the spreading of manure can lead to the accumulation and transport of NO3 - into groundwater, potentially affecting drinking water sources. We investigated the occurrence and distribution of NO3 - in groundwater in Southern Alberta, Canada, a region characterized by intensive crop cultivation and livestock industry. Over 3500 samples from a provincial-scale groundwater quality database, collated from multiple projects and sources, involving domestic wells, monitoring wells, and springs, coupled with newly obtained samples from monitoring wells provided comprehensive geochemical insights into groundwater quality. While stable isotope compositions of NO3 - (δ15N and δ18O) were exclusively available for groundwater samples obtained from monitoring wells, the stable isotope data were instrumental in constraining NO3 - sources and transformation processes within the aquifers of the study region. Among all samples, 49% (n = 1746) were associated with NO3 - concentrations below the detection limits. Ten percent (n = 369) of all groundwater samples, including samples with concentrations below detection limits, exceed the Canadian drinking water maximum acceptable concentration of 10 mg/L for nitrate as nitrogen (NO3 --N). Elevated NO3 - concentrations (> 10 mg/L as NO3 --N) in groundwater were mainly detected at shallow depths (< 30 m) predominantly in aquifers in surficial sediments and less frequently in bedrock aquifers. Statistical correlations between aqueous geochemical parameters showed positive associations between concentrations of NO3 --N and both potassium (K+) and chloride (Cl-), indicating the influence of synthetic fertilizers on groundwater quality. In addition, isotope analyses of NO3 - (δ15N and δ18O) revealed three NO3 - sources in groundwater, including mineralization of soil organic nitrogen followed by nitrification in soils, nitrification of ammonium or urea-based synthetic fertilizers in soils, and manure. However, manure was identified as the dominant source of NO3 - exceeding the maximum acceptable concentration in groundwater within agriculturally dominated areas. Additionally, this multifaceted approach helped identify denitrification in some groundwater samples, a process that plays a key role in reducing NO3 - concentrations under favorable redox conditions in shallow aquifers. The methodological approach used in this study can be applied to other regions worldwide to identify NO3 - sources and removal processes in contaminated aquifers, provided there are well networks in place to monitor groundwater quality and drinking water sources.Supplementary informationThe online version contains supplementary material available at 10.1007/s10533-025-01209-8.

Project description:This article presents data of 623 children (1156 observations) between 4 and 17 years of age living in floricultural communities of Ecuador from 3 examination periods (2008, Apr 2016, and Jul-Oct 2016) as part of the study of Secondary Exposure to Pesticides among Children and Adolescents (ESPINA).We present geospatial data of residential distance to the nearest greenhouse crop and areas within various buffer sizes around homes of participants which is data used in the original research article: Suarez-Lopez JR, et al. "Residential proximity to greenhouse crops and pesticide exposure (via acetylcholinesterase activity) assessed from childhood through adolescence". These geospatial variables are related but different constructs of the potential for off-target drift of pesticides from crops onto homes nearby (via acetylcholinesterase activity) Understanding the associations between these distance and crop area variables is important as a growing number of investigations are using these constructs of off-target pesticide drift to characterize their associations with both exposure biomarkers and outcome measures. Geographic positioning of greenhouses and homes were obtained using GPS receivers and satellite imagery. Distances between homes and the nearest greenhouse edge, and areas of greenhouse crops within various buffer zones (0-150 m, 151-300 m, 310-500 m, 501-750 m, and 751-1000 m) around homes were calculated using Geographic Information System software. Beyond the dataset, we present demographic and anthropometric characteristics, and indicators of pesticide exposure of participants across categories of areas of greenhouse crops around homes for buffer sizes of 0-150 m around homes. We also present the distribution of areas of flower crops within various buffer zone sizes around children's homes and the correlation coefficients between household proximity to the nearest treated greenhouse crops and areas of flower crops within various buffer zones within 1000 m of homes.
