Phosphorus-containing atmospheric aerosols are a substantial source of phosphorus for surface waters in both wet and dry atmospheric deposition. Importance of Phosphorus Containing Atmospheric Aerosols The molecular makeup of biomass-burning organic aerosols is one of the determining variables that influence the climate and the biotic and abiotic entities. Large-scale biomass-burning events, such as wildfire smoke significantly influence the total organic mass loading in the atmosphere. Aerosols are key in maintaining the biogeochemical cycle, air quality, radiative balance, and human health. Effect of Biomass-Burning Organic Aerosol on the EnvironmentĪtmospheric aerosols are planetary variables controlled globally to reduce human impact on the climate and environment. The researchers investigated the molecular makeup of an ambient BBOA sample transformed by wildfire smoke in the Pacific Northwest using Fourier transform-ion cyclotron resonance mass spectrometry, which has extremely high mass accuracy, resolving power, and sensitivity.

Even a slight imbalance in the phosphorus flux significantly impacts water quality by causing algal blooms, eutrophication, and oxygen depletion. A significant source of phosphorus for surface water is biomass-burning organic aerosols. A recent study published in Analytical Chemistry demonstrates the molecular characterization of Organophosphorus compounds in an ambient organic aerosol altered by wildfire smoke.
