Protecting human health from fine particulate matter (PM) pollution is the ambitious goal of clean air actions, but current control strategies largely ignore role source-specific PM toxicity. Here, we proposed health-oriented by integrating unequal toxic potencies most polluting industrial PMs. Iron and steel industry (ISI)-emitted PM2.5 exhibit about one order magnitude higher potency than those cement power industries. Compared with mass-based strategy (prioritizing implementation ultralow...

Cooking emission is known to be a significant anthropogenic source of air pollution in urban areas, but its toxicities are still unclear. This study addressed the fine particulate matter (PM2.5) and gaseous organics by combining chemical fingerprinting analysis with cellular assessments. The cytotoxicity reactive oxygen species activity were ∼1.9 ∼8.3 times higher than those PM2.5, respectively. Moreover, these values per unit mass PM2.5 ∼7.1 ∼15.7 collected from ambient Shanghai. total...

Magnetic particulate matter (PM) has raised increasing concern due to its abundant presence in ambient air and negative health impact. However, there is still a lack of comprehensive understanding their emission sources toxicities. We here report the observation high magnetic property toxicity PM generated during typical welding cutting processes. Magnetite, formed high-temperature operation with less oxygen pressure, was revealed be major contributor. The averaged saturation magnetization...

Environmentally persistent free radicals (EPFRs) have been linked to the generation of reactive oxygen species (ROS) and adverse health effects. However, there remains a knowledge gap regarding dynamic changes in reactivity toxicity during decay process EPFRs emitted from incomplete solid fuel burning, which are identified as primary source EPFRs. Here, we report behavior particulate matter (PM) typical burning associated ROS cytotoxic The freshly produced PM first undergo rapid exponential...

Exposure to atmospheric aerosols threatens human health and is yet be effectively addressed globally. Aerosol toxicity strongly depends upon components whose chemical profiles concentrations can constantly evolve throughout transformation, inhalation, distribution, metabolism, excretion. Despite the abundant studies on aerosol their toxic effects, dynamics in component related biological effects from air body remain unclear. Here, we propose a conceptual toxicokinetic framework...

Abstract Volatile organic compounds (VOCs) emitted from anthropogenic sources are critical precursors to ozone and secondary aerosol (SOA), potential contributors health risks. However, quantitatively estimating the impact of these source‐derived VOCs on air quality is limited by their diverse chemical compositions, resulting in nonselective mass‐based VOC control strategies. To address this issue, we conducted a comprehensive study typical samples freshly various flue gases via field‐based...
