Purpose Global climate change (GCC), especially global  warming, has affected the material cycling (e.g., carbon,  nutrients, and organic chemicals) and the energy flows of  terrestrial ecosystems. Persistent organic pollutants (POPs)  were regarded as anthropogenic organic carbon (OC)  source, and be coupled with the natural carbon (C) and  nutrient biogeochemical cycling in ecosystems. The objective  of this work was to review the current literature and  explore potential coupling processes and mechanisms between  POPs and biogeochemical cycles of C and nutrients  in terrestrial ecosystems induced by global warming.  Results and discussion Global warming has caused many  physical, chemical, and biological changes in terrestrial  ecosystems. POPs environmental fate in these ecosystems  is controlled mainly by temperature and biogeochemical  processes. Global warming may accelerate the reemissions  and redistribution of POPs among environmental  compartments via soil-air exchange. Soil-air exchange is a  key process controlling the fate and transportation of POPs  and terrestrial ecosystem C at regional and global scales.  Soil respiration is one of the largest terrestrial C flux induced  by microbe and plant metabolism, which can affect  POPs biotransformation in terrestrial ecosystems. Carbon  flow through food web structure also may have important  consequences for the biomagnification of POPs in the ecosystems  and further lead to biodiversity loss induced by  climate change and POPs pollution stress. Moreover, the  integrated techniques and biological adaptation strategy  help to fully explore the coupling mechanisms, functioning  and trends of POPs and C and nutrient biogeochemical  cycling processes in terrestrial ecosystems.  Conclusions and perspectives There is increasing evidence  that the environmental fate of POPs has been linked with  biogeochemical cycles of C and nutrients in terrestrial ecosystems  under GCC. However, the relationships between  POPs and the biogeochemical cycles of C and nutrients  are still not well understood. Further study is needed to  explore the coupling mechanisms of POP environmental  fate and C biogeochemical cycle by using the integrated  techniques under GCC scenario and develop biological  and ecological management strategies to mitigate GCC  and environmental stressors.Griffith Sciences, Griffith School of EnvironmentFull Tex
