In the context of China’s commitment to “double carbon” goal, promoting agricultural carbon emission reduction is currently an important research topic. Assessing sequestration level crops has a positive impact on enhancing sinks and reducing emissions. The budget for planting arid oasis Jinchang, northwest China, quantitatively calculated from 2018 2020. average value total absorption by in Ji...

Our objective in this study was to assess the effect of using two kinds of lead-free gasoline [including 92-lead-free gasoline (92-LFG) and 95-lead-free gasoline (95-LFG), rated according to their octane levels] to replace the use of premium leaded gasoline (PLG) on the emissions of polycyclic aromatic hydrocarbons (PAHs) and their corresponding benzo[a]pyrene equivalent (BaP(eq)) amounts from ...
