Abstract. Each year, commercial ships emit over 1.2 Tg of particulate matter (PM) pollution into the atmosphere.

Abstract. Each year, commercial ships emit over 1.67 Tg of particulate matter (PM) pollution into the atmosphere. These rely on combustion heavy fuel oil, which contains high levels sulfur, large aromatic organic compounds, and metals. Vanadium is one metals most commonly associated with oil often used as a tracer for PM from ship exhaust. Previous studies have suggested that vanadium-containing has impacts human health climate due to its toxicological cloud-formation properties, respectively; however, distribution in atmosphere not fully understood, limits our ability quantify environmental implications emitted by ships. Here, we present data obtained Particle Analysis Laser Mass Spectrometry (PALMS) instrument NASA DC-8 aircraft during 2016–2018 Atmospheric Tomography Mission (ATom) show ∼ 1 % accumulation mode particles measured marine boundary layer central Pacific Atlantic oceans contain vanadium. measurements, were made without targeting plumes, suggest widespread Furthermore, observed exhaust at altitudes up 13 km, demonstrates all are immediately removed via wet deposition processes.

Abstract Chemicals of emerging concern (CECs), like organophosphate esters (OPEs), are toxic substances threatening human/wildlife health. Yet the atmospheric transformation CECs remains poorly understood. Here we combine field measurements and partitioning models to test hypothesis that secondary formation OPEs could be enhanced by heterogenous processes in aerosols. We found hydrophobic absorbed favorably into organic phase, whereas hydrophilic preferably partition aqueous phase. provide evidence occurs winter, magnitude is strongly dependent on aerosol water content. suggest dissolved inorganic salts transitional metals aerosols impact positively particle-bound OPEs, facilitating their and/or oxidation. Our findings highlight important role oxidation chemistry for fate atmosphere, urging a better consideration products future risk assessment chemicals management.
