Poor air quality is globally the largest environmental health risk. Epidemiological studies have uncovered clear relationships of gaseous pollutants and particulate matter (PM) with adverse outcomes, including mortality by cardiovascular respiratory diseases. Studies impacts aerosols are highly multidisciplinary a broad range scales in space time. We assess recent advances future challenges regarding aerosol effects on from molecular to global through epidemiological studies, field measurements, health-related properties PM, multiphase interactions oxidants PM upon deposition.

Atmospheric new particle formation and growth: review of field observations

Environmental Research Letters, Journal Year: 2018, Volume and Issue: 13(10), P. 103003 - 103003

Published: Sept. 6, 2018

This review focuses on the observed characteristics of atmospheric new particle formation (NPF) in different environments global troposphere. After a short introduction, we will present theoretical background that discusses methods used to analyze measurement data NPF and associated terminology. We update our current understanding regional NPF, i.e. taking simultaneously place over large spatial scales, complement with full reported growth rates during events. shortly at sub-regional scales. Since newly-formed particles into larger sizes is great interest, briefly discuss observation-based which gaseous compounds contribute particles, what implications this have cloud condensation nuclei formation. finish summary main findings future outlook outlines remaining research questions needs for additional measurements.

Production of extremely low volatile organic compounds from biogenic emissions: Measured yields and atmospheric implications

Proceedings of the National Academy of Sciences, Journal Year: 2015, Volume and Issue: 112(23), P. 7123 - 7128

Published: May 26, 2015

Significance Extremely low volatility organic compounds (ELVOC) are suggested to promote aerosol particle formation and cloud condensation nuclei (CCN) production in the atmosphere. We show that capability of biogenic VOC (BVOC) produce ELVOC depends strongly on their chemical structure relative oxidant levels. BVOC with an endocyclic double bond, representative emissions from, e.g., boreal forests, efficiently from ozonolysis. Compounds exocyclic bonds or acyclic including isoprene, emission tropics, minor quantities ELVOC, role OH radical oxidation is relatively larger. Implementing these findings into a global modeling framework shows detailed assessment pathways crucial for understanding secondary atmospheric CCN formation.

Resonance-stabilized hydrocarbon-radical chain reactions may explain soot inception and growth

Science, Journal Year: 2018, Volume and Issue: 361(6406), P. 997 - 1000

Published: Sept. 6, 2018

Mystery surrounds the transition from gas-phase hydrocarbon precursors to terrestrial soot and interstellar dust, which are carbonaceous particles formed under similar conditions. Although polycyclic aromatic hydrocarbons (PAHs) known high-temperature carbonaceous-particle formation, molecular pathways that initiate particle formation unknown. We present experimental theoretical evidence for rapid clustering-reaction involving radicals with extended conjugation. These react other species form covalently bound complexes promote further growth clustering by regenerating resonance-stabilized through low-barrier hydrogen-abstraction hydrogen-ejection reactions. Such radical-chain reaction may lead clusters of PAHs would otherwise be too small condense at high temperatures, thus providing key mechanistic steps surface chemisorption.

New particle formation in the free troposphere: A question of chemistry and timing

Science, Journal Year: 2016, Volume and Issue: 352(6289), P. 1109 - 1112

Published: May 26, 2016

From neutral to new Many of the particles in troposphere are formed situ, but what fraction all tropospheric do they constitute and how exactly made? Bianchi et al. report results from a high-altitude research station. Roughly half were newly by condensation highly oxygenated multifunctional compounds. A combination laboratory results, field measurements, model calculations revealed that nucleation is more than 10 times faster ion-induced nucleation, particle growth rates size-dependent, formation occurs during limited time window.

Influence of vapor wall loss in laboratory chambers on yields of secondary organic aerosol

Proceedings of the National Academy of Sciences, Journal Year: 2014, Volume and Issue: 111(16), P. 5802 - 5807

Published: April 7, 2014

Secondary organic aerosol (SOA) constitutes a major fraction of submicrometer atmospheric particulate matter. Quantitative simulation SOA within air-quality and climate models--and its resulting impacts--depends on the translation formation observed in laboratory chambers into robust parameterizations. Worldwide data have been accumulating indicating that model predictions are substantially lower than ambient observations. Although possible explanations for this mismatch advanced, none has addressed chamber themselves. Losses particles to walls routinely accounted for, but there little evaluation effects losses semivolatile vapors walls. Here, we experimentally demonstrate such vapor can lead underestimated formation, by factors as much 4. Accounting clear potential bring observations levels closer agreement.
