Cardiovascular Emergency Hospitalization Risks of PM_2.5 Transition Metals: A Time-Stratified Case-Crossover Study

Environment & Health, Journal Year: 2025, Volume and Issue: 3(4), P. 402 - 413

Published: Jan. 7, 2025

PM2.5 pollution poses significant health risks in urban areas, yet the specific cardiovascular impacts of its hazardous components, especially transition metals, remain insufficiently understood. This study evaluated associations components on acute myocardial infarction (AMI) and aortic dissections (AAD) emergency hospitalizations (n = 9985) using a time-stratified case-crossover between 2017 2023 Xiamen, China. We collected comprehensive data daily air pollutants, (water-soluble ions, carbon other elements), meteorological variables. Conditional logistic regressions were used to estimate odds ratios (OR) per interquartile range (IQR) exposures. Our finding reveals short-term exposures pollutants with increased hospitalizations. The strongest observed cumulative 3-day lagged (lag 0–3) metals including Mn [odds ratio, OR 1.106 (95% CI: 1.032–1.186)], Fe [OR 1.078, 1.015–1.145)], V 1.117 1.024–1.219)], Zn 1.08, 1.005–1.161)] exposure AMI.

Aerosol Toxicokinetics: A Framework for Unraveling Toxicological Dynamics from Air to the Body

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

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 mathematically deduce bioavailable concentration changing bulk of constituents atmosphere. The single or multiple are further predicted via toxicodynamic modeling according concentrations. Atmospheric composition turn regulated by risk-based guidelines, aiming alleviate vivo effects. This perspective demonstrates how serial toxicokinetic-toxicodynamic equations bridge knowledge gap between ambient associated bodies. prediction an inhalation also allows connecting with exposomes aggregate exposure pathways. We call for development model validity integrate quantitative adverse outcome pathways apply exposure-disease modeling, providing novel insights into quality policymaking public management.

Elucidating Decade-Long Trends and Diurnal Patterns in Aerosol Acidity in Shanghai

Atmosphere, Journal Year: 2024, Volume and Issue: 15(8), P. 1004 - 1004

Published: Aug. 20, 2024

Aerosol acidity is a critical factor affecting atmospheric chemistry. Here, we present study on annual, monthly, and daily variations in PM2.5 pH Shanghai during 2010–2020. With the effective control of SO2 emissions, NO2/SO2 ratio increased from 1.26 2010 to 5.07 2020 NO3−/SO42− 0.68 1.49. decreased 3.27 2.93 2020, regardless great achievement reducing industrial NOx emissions. These findings suggest that aerosol might not be significantly reduced response The monthly variation values exhibited V-shape trend, mainly attributable compositions temperature. Atmospheric NH3 plays decisive role buffering particle acidity, whereas Ca2+ K+ are important buffers, distinct decline 2010–2016 was associated with reduction while both temperature SO42− were drivers winter. Sensitivity tests show increases increasing relative humidity summer it sensitive winter due proportional Hair+ liquid water content (ALWC). Our results emissions will affect

Absence of a Causal Link between Elemental Carbon Exposure and Short-Term Respiratory Toxicity in Human-Derived Organoids and Cellular Models

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Black carbon or elemental (EC) in the atmosphere plays an ambiguous role acute respiratory toxic effects. Here, we evaluate contribution of EC to short-term toxicity (including cytotoxicity and oxidative stress potency) fine particulate matter (PM2.5) on human tract using vitro airway organoids cell lines. The potency per unit mass, including char soot, is more than 2 orders magnitude lower that polycyclic aromatic hydrocarbons (PAHs), which are coemitted from incomplete combustion. contributes approximately 1 order less PM2.5 PAHs, despite its positive associations with PM2.5-induced (p < 0.0001). Furthermore, PAHs contribute 71.9 ± 12.2% 61.9 32.8% overall emitted typical burning solid liquid fuels, respectively, while significantly correlates content (r = 0.94, p 0.002). Hence, not a cause inducing toxicity, likely attributed PAHs. These findings provide causal evidence for understanding health risks associated exposure further benefit establishing efficient air pollution control policies.
