The combined influences of species selection (Avicennia marina, Kandelia obovata) and site elevation (BSL site, below local mean sea level; ASL site, above local mean sea level) on the greenhouse gas fluxes (nitrous oxide (NO), methane (CH) and carbon dioxide (CO)) from restored mangrove soils are investigated in this study. Compared with the A. marina forest, soils in the K. obovata forest at ASL site have higher CO fluxes, while higher NO fluxes in the K. obovata forest are found at BSL site. The highest CH fluxes are found at BSL site in the A. marina forest. At each elevation site, the A. marina forest has lower CO-equivalent fluxes and carbon release in the form of carbon-containing gases. The results suggest that A. marina should be selected for mangrove restoration to minimize carbon release and reduce influence of greenhouse gas fluxes on the global greenhouse effect.

Versatile nitrate-respiring heterotrophs are previously concealed contributors to sulfur cycle.

Heterotrophic denitrifiers play crucial roles in global carbon and nitrogen cycling. However, their inability to oxidize sulfide renders them vulnerable to this toxic molecule, which inhibits the key enzymatic reaction responsible for reducing nitrous oxide (NO), thereby raising greenhouse gas emissions. Here, we applied microcosm incubations, community-isotope-corrected DNA stable-isotope probing, and metagenomics to characterize a cohort of heterotrophic denitrifiers in estuarine sediments that thrive by coupling sulfur oxidation with denitrification through chemolithoheterotrophic metabolism.

Assessing sub-Saharan Africa's GHG emissions from croplands: environmental impacts and sustainable mitigation strategies.

Globally, agricultural lands are among the top emitters of greenhouse gases (GHGs), responsible for over 20% of total greenhouse gas (GHG) emissions. Climatic conditions, an acute challenge in sub-Saharan Africa (SSA), where access to mitigation technologies remains limited, have heavily influenced these lands. This study explores GHG contributions from crop production and their devastating and deteriorating impacts on the economy and environment and proposes a sustainable solution.

Delivery of health care, including medical imaging, generates substantial global greenhouse gas emissions. The cardiovascular magnetic resonance (CMR) community has an opportunity to decrease our carbon footprint, mitigate the effects of the climate crisis, and develop resiliency to current and future impacts of climate change. The goal of this document is to review and recommend actions and strategies to allow for CMR operation with improved sustainability, including efficient CMR protocols and CMR imaging workflow strategies for reducing greenhouse gas emissions, energy, and waste, and to decrease reliance on finite resources, including helium and waterbody contamination by gadolinium-based contrast agents.

Floating photovoltaics strongly reduce water temperature: A whole-lake experiment.

Floating photovoltaics (FPVs), solar panels installed on floating structures in freshwater ecosystems such as lakes, represent a growing renewable technology aimed at decarbonizing the energy sector. However, robust empirical assessments of its environmental effects are still lacking. We used a Before-After-Control-Impact design replicated at the ecosystem level (n = 6 lakes: three lakes with FPV compared to three non-FPV lakes) to determine the global effects of FPV on water temperature over three years and allowing to isolate FPV effects from natural variability.

Sustainable removal of gaseous Hg using sulfur functionalized biochar: Adsorption experiment and life cycle assessment.

Chemosphere

Department of Environmental Engineering, Korea University Sejong Campus, 2511 Sejong-ro, Sejong City, 30019, Republic of Korea. Electronic address:

Maximizing the sorption capacity of gaseous Hg by sulfur-functionalized biochar can lead to increased energy consumption and the production of secondary environmental pollutants such as greenhouse gases. This study evaluates the environmental impact of producing sulfurized biochar through a life cycle assessment (LCA), weighing these impacts against the benefits of enhanced Hg removal efficiencies. The biochar's Hg adsorption capacity, which ranges between 3 and 22 μg-Hg/g-biochar, is influenced by several factors: it increases with higher sulfur loading (0-15 %), higher O levels (0-21 %), and longer pyrolysis times (1-5 h).
