Fungi are known to be crucial in the formation and stabilization of soil organic matter through their exudates and dead residues (necromass). Yet, it remains unclear how fungi contribute to the persistence of carbon in soils over millennial scales across biomes. Here, this study fills the knowledge gap by linking fungal carbon stocks with minerals-associated carbon stocks across major biomes. A strong correlation between fungal biomass and reactive mineral-associated carbon stocks in soils across six biomes supports the substantial role of fungi in soil carbon persistence at the global level. High spatial resolution nanoscale secondary ion mass spectrometry revealed that fungi may stabilize carbon by forming organo-mineral associations through their close physical connection to reactive minerals and weathered nanoparticles. We propose a conceptual model that emphasizes the dualistic role of hypha-mineral interactions:(i) fungi accelerate organic matter decomposition by producing reactive oxygen species on the hypha-mineral interfaces, and (ii) fungi stabilize their residues on mineral surfaces, leading to millennial scale persistence of soil C. Concluding, fungi play a fundamental role in ecosystems that extends beyond the decomposition of persistent carbon. They are crucial in stabilizing carbon on mineral surfaces, thereby facilitating the long-term removal of carbon from rapid biotic cycling.

A Review of the Distribution Coefficient (K_d) of Some Selected Heavy Metals over the Last Decade (2012-2021)

Journal of Geoscience and Environment Protection 2022年第8期10卷 199-242页

作者： Chabi Dari Seidou Tiejun Wang Mikouendanandi Mouendo Rahmat Brice Espoire Yibin Dai Yutao Zuo Institute of Surface-Earth System Science School of Earth System Science Tianjin University Tianjin China Tianjin bohai Rim coastal Earth critical zone national observation and research station Tianjin University Tianjin China Tianjin Key Laboratory of Earth critical zone Science and Sustainable Development in bohai Rim Tianjin University Tianjin China

This review synthesizes the methods for estimating the distribution coefficient (Kd) and provides a compilation of Kd values for five heavy metals (As, Pb, Cd, Cu, and Zn) based on research published in the last decade (2012-2021). We used the PRISMA method to ensure the transparency of the collected data. For mono-metal systems (MS), the Kd values ranged from 10-2 to 107 L/kg for Pb, from 10-2 to 106 L/kg for Cd, As, and Zn, and from 10-2 to 105 L/kg for Cu. In competitive systems (CS), the Kd values ranged from 10-2 to 105 L/kg for Cu, and 10-2 to 104 L/kg for Pb, Cd, and Zn, while no Kd value for As was reported under CS. It was found that the Kd values of heavy metals are affected not only by soil chemical and physical properties but also by the nature and characteristics of the metal involved along with experimental conditions. The totals references number of Kd data observation per element metal are represented as follows: Cd 35 (50%), Zn 35 (50%), Pb 33 (47.14%), Cu 33 (47.14%), and As 19 (27.14%). Overall, most research was done 1) on MS rather than CS, 2) on sorption rather than desorption, 3) on soil rather than sediments , and 4) most literature have reported the Kd values, derived from batch method than on column method. Despite significant progress over the past decade towards a better understanding of the variation in Kd values and the effect of factors influencing them to provide important parameters for predicting and controlling toxic metals in soils, additional research is still warranted to the complexity of underlying processes.
