Assessing nitrous oxide emissions from algal-bacterial photobioreactors devoted to biogas upgrading and digestate treatment

Chemosphere, Год журнала: 2024, Номер 361, С. 142528 - 142528

Опубликована: Июнь 3, 2024

Nitrous oxide (N2O) emissions in High Rate Algal Ponds (HRAP) can negatively affect the sustainability of algal-bacterial processes. N2O from a pilot HRAP devoted to biogas upgrading and digestate treatment were herein monitored for 73 days. The influence pH (7.5, 8.5, 9.5), nitrogen sources (100 mg/L N-NO2-, N-NO3-, N-NH4+) illumination on biomass was also assessed batch tests. Significantly higher gas concentrations 311.8 ± 101.1 ppmv recorded dark compared illuminated period (236.9 82.6 ppmv) HRAP. tests revealed that highest emission rates (49.4 mmol g-1 TSS·h-1) occurred at 8.5 presence 100 mg N-NO2-/L under conditions. This study significant HRAPs during darkness.

Tapping Carbon Sequestration Potential of Blooming Macroalgae to Mitigate Climate Change

Ocean-Land-Atmosphere Research, Год журнала: 2023, Номер 2

Опубликована: Янв. 1, 2023

Macroalgal mariculture is gaining global attention to achieve carbon neutrality due its important contribution ocean sequestration. However, some wild macroalgal species (e.g., Sargassum and Ulva prolifera ) exhibit strong environmental adaptability can cause large-scale, recurrent blooms in oceans, fueled by rising atmospheric CO 2 levels coastal eutrophication. Notably, massive green tides have occurred annually the Yellow Sea for past 17 consecutive years. At late blooming stage, millions of tons U. naturally sink shallow seafloor. The subsequent intense microbial aerobic degradation sinking macroalgae results hypoxia acidification, with most returning atmosphere. Preventing or reducing could enable more storage long term alleviate harmful effects tide. Thus, ecological disasters from may be transformed into useful natural platforms increase We propose an integrated strategy using environmentally friendly minerals montmorillonite calcium carbonate) coagulants polyaluminum chloride), along algicidal bacteria substances, induce rapid flocculation sedimentation macroalgae, reduce negative impacts, minimize generation propagules seeds potential risk future tide outbreaks. This approach potentially a promising tap sequestration mitigate climate change.

Spatio-temporal differences and simulation studies of the carbon budget from fisheries in the northern marine economic circle of China

Frontiers in Marine Science, Год журнала: 2024, Номер 11

Опубликована: Июнь 11, 2024

With the proposal of dual carbon goals, enhancing sinks and reducing emissions has become a critical issue. Fisheries, as component agriculture, possess attributes being “carbon sink” (biological fixation) source” (the from fishing vessels). Therefore, it is necessary to assess sink emission levels fisheries. The northern marine economic circle, which includes Liaoning, Hebei, Tianjin, Shandong, an important site for fisheries in China, characterized by abundant aquatic resources. However, comprehensive assessment budget this region still unclear. This study calculated sinks, emissions, net associated with 2013 2020. Additionally, we used sensitivity analysis scenario simulation explore factors influencing emissions. results revealed that circle was deficit amount higher than sinks) downward trend observed, indicating potential achieving neutrality. From perspective provinces, significant differences among provinces (cities) were found terms Shandong having largest Furthermore, production clams use seawater trawl have impact on Increasing while power trawling operations can significantly decrease Based these results, provides relevant suggestions enhance capacity circle.
