Masquerading as soil carbon storage, microplastics can distort assessments of the soil carbon pool by introducing plastic-carbon and associated leachates, influencing soil organic matter (SOM) turnover through priming effects (e.g., dilution, substrate switching, and co-metabolisms). Additionally, microplastics can …

Mycorrhizal fungi are a major global carbon pool, drawing an average of ∼3–13% but up to ∼50% of a plant partner''s NPP belowground when hosts are associated with the main mycorrhizal types. We estimate a flux of ∼13 Gt of CO 2 e moves through plants into carbon that is allocated to mycorrhizal mycelium every year.

The objective of this study is to propose a framework for optimizing LULC, …
Note that the carbon sources from Group A converge to the node (G6P/F6P) before entering various pools, while the carbon sources from Group B can take other routes (Fig. 1).
Introduction Carbon (C) circulates globally among three distinct pools: the atmosphere, the ocean, and the land biosphere. The atmosphere pool carries 762 petagrams (1 Pg = 10 15 g) of C, chiefly in the form of CO 2 [Citation 1] .The atmospheric concentration of CO 2 reached a record of 417.1 ppm in 2020 or 147% of the pre …
The total amount of carbon in the world''s soils is estimated to be 1500 PgC. Measuring soil. carbon can be challenging, but a few basic assumptions can make estimating it much easier. First, the most prevalent form of carbon in the soil is organic carbon derived from dead plant materials and microorganisms.
The 14th Five-year Plan is an important new window for the development of the energy storage industry, in which energy storage will become a key supporting …

carbon pools accounting for changes in growth, mortality and decomposition. Products were ex-ported from the forest module to the product module, which then calculated carbon pools in products, as well as the carbon associated with energy use in theirsembly.
The carbon pool includes carbon sources that produce and release carbon and carbon sinks that store carbon (Zhang et al., 2013a). For the vegetation carbon pool, photosynthesis is the main input process, and produces, wastes and biological energy utilization are the main output processes ( Fig. 2 ).
In 2023, announced capture capacity for 2030 increased by 35%, while announced storage capacity rose by 70%. This brings the total amount of CO2 that could be captured in 2030 to around 435 million tonnes (Mt) per year and announced storage capacity to around 615 Mt of CO2 per year. While this momentum from announcements is positive, it still ...

Carbon is transported in various forms through the atmosphere, the hydrosphere, and geologic formations. One of the primary pathways for the exchange of carbon dioxide (CO 2) takes place between the atmosphere and the oceans; there a fraction of the CO 2 combines with water, forming carbonic acid (H 2 CO 3) that subsequently …
