Influence of meteorological conditions on PM2.5 concentrations across China: A review of methodology and mechanism

Environment International, Journal Year: 2020, Volume and Issue: 139, P. 105558 - 105558

Published: April 8, 2020

Air pollution over China has attracted wide interest from public and academic community. PM2.5 is the primary air pollutant across China. Quantifying interactions between meteorological conditions concentrations are essential to understand variability of seek methods control PM2.5. Since 2013, measurement been widely made at 1436 stations country more than 300 papers focusing on PM2.5-meteorology have published. This article a comprehensive review impact concentrations. We start with an introduction general China, then seasonal spatial variations influences Next, major used quantify checked compared. find that causality analysis suitable for extracting influence individual factors whilst statistical models good quantifying overall effect multiple Chemical Transport Models (CTMs) potential provide dynamic estimation by considering anthropogenic emissions transport evolution pollutants. comprehensively examine mechanisms how may concentrations, including dispersion, growth, chemical production, photolysis, deposition The feedback effects also carefully examined. Based this review, suggestions future research approaches mitigating finally.

Siberian Arctic black carbon sources constrained by model and observation

Proceedings of the National Academy of Sciences, Journal Year: 2017, Volume and Issue: 114(7)

Published: Jan. 30, 2017

Significance A successful mitigation strategy for climate warming agents such as black carbon (BC) requires reliable source information from bottom-up emission inventory data, which can only be verified by observation. We measured BC in one of the fastest-warming and, at same time, substantially understudied regions on our planet, northeastern Siberian Arctic. Our observations, compared with an atmospheric transport model, imply that quantification and spatial allocation emissions high latitudes, specifically Russian Arctic, need improvement reallocating significantly shifting contributions transport, domestic, power plant, gas flaring sectors. This strong shift reported has potentially considerable implications modeling efforts.

Enrichment of Saccharides and Divalent Cations in Sea Spray Aerosol During Two Phytoplankton Blooms

Environmental Science & Technology, Journal Year: 2016, Volume and Issue: 50(21), P. 11511 - 11520

Published: Oct. 6, 2016

Sea spray aerosol (SSA) is a globally important source of particulate matter. A mesocosm study was performed to determine the relative enrichment saccharides and inorganic ions in nascent fine (PM2.5) coarse (PM10-2.5) SSA sea surface microlayer (SSML) bulk seawater. Saccharides comprise significant fraction organic matter (11 27%, respectively). Relative sodium, individual were enriched 14-1314-fold SSA, 3-138-fold but only up 1.0-16.2-fold SSML. Enrichments SSML attributed rising bubbles that scavenge surface-active species from seawater, while further likely derives bubble films. Mean factors for major demonstrated potassium (1.3), magnesium (1.4), calcium (1.7), because their interactions with Consequently, develops salt profile significantly different Maximal enrichments coincided second two phytoplankton blooms, signifying influence ocean biology on selective mass transfer across ocean-air interface.
