Abstract

Agriculture is directly related to food security, which is highly dependent on and significantly impacts resources and the environment. Sustainable agriculture development is key to achieving the sustainable development goals. Frontiers, hot topics, and trends of sustainable agriculture development were summarized for scientific research and decision-making by CiteSpace based on 1 174 papers published in the Web of Science and 1 043 papers published in China National Knowledge Infrastructure from 2000 to 2019. Results showed that the frontiers were mainly focused on"food system resilience and food security", "ecological intensification and sustainable intensification", "agricultural muti-functionality and urban agriculture", and"trade-offs and synergies of ecosystem services in agroecosystem". Hotspots included how climate change impacts agricultural systems and its adaptive management, ecosystem services management in agro-ecosystems, and the environmental impact assessment of agricultural activities and integrated sustainability assessment of an agricultural system. It is suggested that the coupling mechanism of the"climate-land-water-energy-food"nexus should be further analyzed, and"influencing factors-action mechanisms-regulation methods"of agro-ecosystem should be systematically studied in the future.

Abstract

As brominated flame retardants (BFRs), tetrabromobisphenol A/S (TBBPA/S) and their derivatives have raised wide concerns owing to their widely usage, distributions and adverse effects on human health, thus monitoring these BFRs was urgently needed. In this study, a rapid and cost-effective method based on thin-layer chromatography (TLC) sample pre-treatment coupled with high performance liquid chromatography-diode array detector (HPLC-DAD) (UV=214nm) was developed for determining TBBPA/S and their derivatives in soils, including TBBPA, TBBPA bis(allyl ether) (TBBPA-BAE), TBBPA bis(2,3-dibromopropyl ether) (TBBPA-BDBPE), TBBPS bis(allyl ether) (TBBPS-BAE) and TBBPS bis(2,3-dibromopropyl ether) (TBBPS-BDBPE). The method detection limits (MDLs) and the method quantification limits (MQLs) for these BFRs ranged from 0.023 to 0.087μgg-1dw and 0.076-0.29μgg-1dw, respectively. The recoveries were 41-108% and both RSD of repeatability and intermediate precision were less than 11%. The developed method presented good performance for analyzing natural soil samples collected from BFRs industrial park, suggesting its great application potential for monitoring environmental TBBPA/S and their derivatives.
